Enzymes for carbohydrate digestion -

Digestion and absorption of carbohydrates in the small intestine. Fructose and galactose are converted to glucose in the liver.

Once absorbed carbohydrates pass through the liver, glucose is the main form of carbohydrate circulating in the bloodstream. Instead, bacteria living in the large intestine, sometimes called our gut microbiota, ferment these carbohydrates to feed themselves. Fermentation also produces short-chain fatty acids, which our large intestine cells can use as an energy source.

Over the last decade or so, more and more research has shown that our gut microbiota are incredibly important to our health, playing important roles in the function of our immune response, nutrition, and risk of disease. A diet high in whole food sources of fiber helps to maintain a population of healthy gut microbes.

The primary goal of carbohydrate digestion is to break polysaccharides and disaccharides into monosaccharides, which can be absorbed into the bloodstream.

After eating, nothing needs to happen in the digestive tract to the monosaccharides in a food like grapes, because they are already small enough to be absorbed as is. Disaccharides in that grape or in a food like milk are broken down enzymatically digested in the digestive tract to monosaccharides glucose, galactose, and fructose.

Starch in food is broken down enzymatically digested in the digestive tract to glucose molecules. However, some dietary fiber is fermented in the large intestine by gut microbes. Is this carbohydrate enzymatically digested?

enzyme name. It is then transported to the liver where it is converted to glucose. This video will help you identify carbohydrates in foods, what carbohydrates need to be enzymatically digested, and what is absorbed. A digestive enzyme produced by the salivary glands; starts the chemical breakdown of starch or amylose.

An enzyme secreted from the pancreas into the small intestine; continues the chemical breakdown of starch to smaller glucose chains and maltose. An enzyme produced by the enterocytes; breaks lactose into its building blocks, glucose and galactose.

An enzyme produced by the enterocytes; breaks sucrose into its building blocks, glucose and fructose. Nutrition: Science and Everyday Application, v. Skip to content Imagine taking a bite of pizza. What types of carbohydrates would you find in that bite?

Lactose from the cheese Sucrose, glucose, and fructose from the naturally-occurring sugars in the tomatoes, as well as sugar that may have been added to the sauce Starch in the flour used to make the crust Fiber in the flour, tomatoes, and basil In order to use these food carbohydrates in your body, you first need to digest them.

Carbohydrate Digestion In the image below, follow the numbers to see what happens to carbohydrates at each site of digestion. The enzyme pepsin plays an important role in the digestion of proteins by breaking down the intact protein to peptides, which are short chains of four to nine amino acids.

In the duodenum, other enzymes— trypsin , elastase , and chymotrypsin —act on the peptides reducing them to smaller peptides. Trypsin elastase, carboxypeptidase, and chymotrypsin are produced by the pancreas and released into the duodenum where they act on the chyme. Further breakdown of peptides to single amino acids is aided by enzymes called peptidases those that break down peptides.

Specifically, carboxypeptidase , dipeptidase , and aminopeptidase play important roles in reducing the peptides to free amino acids. The amino acids are absorbed into the bloodstream through the small intestines. The steps in protein digestion are summarized in Figure 2 and Table 2. Figure 2.

Protein digestion is a multistep process that begins in the stomach and continues through the intestines. Lipid digestion begins in the stomach with the aid of lingual lipase and gastric lipase.

However, the bulk of lipid digestion occurs in the small intestine due to pancreatic lipase. When chyme enters the duodenum, the hormonal responses trigger the release of bile, which is produced in the liver and stored in the gallbladder.

Bile aids in the digestion of lipids, primarily triglycerides by emulsification. Emulsification is a process in which large lipid globules are broken down into several small lipid globules. These small globules are more widely distributed in the chyme rather than forming large aggregates.

Lipids are hydrophobic substances: in the presence of water, they will aggregate to form globules to minimize exposure to water. Bile contains bile salts, which are amphipathic, meaning they contain hydrophobic and hydrophilic parts. Thus, the bile salts hydrophilic side can interface with water on one side and the hydrophobic side interfaces with lipids on the other.

By doing so, bile salts emulsify large lipid globules into small lipid globules. Why is emulsification important for digestion of lipids?

Pancreatic juices contain enzymes called lipases enzymes that break down lipids. If the lipid in the chyme aggregates into large globules, very little surface area of the lipids is available for the lipases to act on, leaving lipid digestion incomplete.

By forming an emulsion, bile salts increase the available surface area of the lipids many fold. The pancreatic lipases can then act on the lipids more efficiently and digest them, as detailed in Figure 3. Lipases break down the lipids into fatty acids and glycerides.

These molecules can pass through the plasma membrane of the cell and enter the epithelial cells of the intestinal lining. The bile salts surround long-chain fatty acids and monoglycerides forming tiny spheres called micelles.

The micelles move into the brush border of the small intestine absorptive cells where the long-chain fatty acids and monoglycerides diffuse out of the micelles into the absorptive cells leaving the micelles behind in the chyme.

The long-chain fatty acids and monoglycerides recombine in the absorptive cells to form triglycerides, which aggregate into globules and become coated with proteins. These large spheres are called chylomicrons.

Chylomicrons contain triglycerides, cholesterol, and other lipids and have proteins on their surface. Together, they enable the chylomicron to move in an aqueous environment without exposing the lipids to water. Chylomicrons leave the absorptive cells via exocytosis. Chylomicrons enter the lymphatic vessels, and then enter the blood in the subclavian vein.

Vitamins can be either water-soluble or lipid-soluble. Fat soluble vitamins are absorbed in the same manner as lipids. It is important to consume some amount of dietary lipid to aid the absorption of lipid-soluble vitamins.

Foods with a high GI are more quickly digested, and cause a larger increase in blood glucose level compared to foods with a low GI. Foods with a low GI are digested more slowly and do not raise blood glucose as high, or as quickly, as high GI foods.

Examples of factors that affect carbohydrate absorption are described in the table below:. Less processed foods, such as slow cooking oats or brown rice, have a lower GI than more processed foods such as instant oats or instant rice.

Pasta cooked 'al dente' tender yet firm has a lower GI than pasta cooked until very tender. David Kitts Faculty of Land and Food Systems, University of British Columbia Dietary carbohydrates include starches, sugars, and fibre. Use of Dietary Carbohydrates as Energy. Glucose is the primary energy source of the body.

Major dietary sources of glucose include starches and sugars. Digestion of Carbohydrates. The digestion and absorption of dietary carbohydrates can be influenced by many factors. Absorption of Carbohydrates.

Absorbed carbohydrate molecules are used immediately for energy or stored in various forms in the muscles, liver or adipose tissue for future use.

Use of Dietary Carbohydrates as Energy Dietary carbohydrates include starches, sugars and fibre that are mostly found in grain products, vegetables and fruit, milk products, and meat alternatives such as nuts, seeds, and legumes 1, 2.

Muscles use glucose for energy, especially during high-intensity exercise. Absorption of Carbohydrates The end products of sugars and starches digestion are the monosaccharides glucose, fructose, and galactose. Absorption of Fructose There are two major pathways for the metabolism of fructose 5, 6 : the more prominent pathway is in the liver and the other occurs in skeletal muscle.

Ofr liver takes them up and converts galactose to carbohgdrate, breaks fructose into even smaller carbon-containing units, and either stores glucose as glycogen or exports it back to the blood.

How much glucose the liver exports to the blood is under hormonal control and you will soon discover that even the glucose itself regulates its concentrations in the blood. If needed for energy, glucose is released from the liver to the bloodstream, and on to cells that need it.

Excess glucose is converted to glycogen in the liver and muscles and stored in those organs. The glycogen stored in the liver maintains blood glucose between meals; muscle glycogen provides immediate energy to the muscle during exercise. Enzymes in the liver and muscles combine glucose molecules to form glycogen through a process known as glycogenesis.

Once the storage capacity of the liver and muscles is reached, excess glucose is stored as fat. Glucose levels in the blood are tightly controlled, as having either too much or too little glucose in the blood can have health consequences.

Glucose regulates its levels in the blood via a process called negative feedback. An everyday example of negative feedback is in your oven because it contains a thermostat.

When you set the temperature to bake a dessert at °F the thermostat senses the temperature and sends an electrical signal to turn the elements on and heat up the oven.

When the temperature reaches °F the thermostat senses the temperature and sends a signal to turn the element off. The glucose thermostat is located within the cells of the pancreas.

After eating a meal containing carbohydrates, glucose levels rise in the blood. Beta cells in the pancreas sense the increase in blood glucose and release a hormone, insulin, into the blood.

Glucose can be stored only in muscle and liver tissues. In these tissues it is stored as glycogen, a highly branched macromolecule consisting of thousands of glucose molecules. Glycogen levels do not take long to reach their physiological limit and when this happens excess glucose will be converted to fat.

Insulin has an opposing hormone called glucagon. As the time after a meal increases, glucose levels decrease in the blood. Alpha cells in the pancreas sense the drop in glucose and, in response, release glucagon into the blood.

Glucagon communicates to the cells in the body to stop using all the glucose. More specifically, it signals the liver to begin glycogenolysis the break down of glycogen into glucose and release the stored glucose into the blood, so that glucose levels stay within the target range and all cells get the needed fuel to function properly.

If additional glucose is needed, glucagon will stimulate the production of new glucose from amino acids a process known as gluconeogenesis. Almost all of the carbohydrates, except for dietary fiber and resistant starches, are efficiently digested and absorbed into the body.

Some of these remaining indigestible carbohydrates are broken down by enzymes released by bacteria in the large intestine. The products of bacterial digestion of these complex carbohydrates are short-chain fatty acids and some gases. The short-chain fatty acids are either used by the bacteria to make energy and grow, are eliminated in the feces, or are absorbed into cells of the colon, with a small amount being transported to the liver.

Colonic cells use the short-chain fatty acids to support some of their functions. The liver can also metabolize the short-chain fatty acids into cellular energy. The yield of energy from dietary fiber is about 2 calories per gram for humans, but is highly dependent upon the fiber type, with soluble fibers and resistant starches yielding more energy than insoluble fibers.

Since dietary fiber is digested much less in the gastrointestinal tract than other carbohydrate types simple sugars, many starches the rise in blood glucose after eating them is less, and slower. These physiological attributes of high-fiber foods i. whole grains are linked to a decrease in weight gain and reduced risk of chronic diseases, such as Type 2 diabetes and cardiovascular disease.

Water-soluble vitamins can be directly absorbed into the bloodstream from the intestine. Figure 4. Mechanical and chemical digestion of food takes place in many steps, beginning in the mouth and ending in the rectum. The final step in digestion is the elimination of undigested food content and waste products. The undigested food material enters the colon, where most of the water is reabsorbed. The semi-solid waste is moved through the colon by peristaltic movements of the muscle and is stored in the rectum. As the rectum expands in response to storage of fecal matter, it triggers the neural signals required to set up the urge to eliminate. The solid waste is eliminated through the anus using peristaltic movements of the rectum. Diarrhea and constipation are some of the most common health concerns that affect digestion. Constipation is a condition where the feces are hardened because of excess water removal in the colon. In contrast, if enough water is not removed from the feces, it results in diarrhea. Many bacteria, including the ones that cause cholera, affect the proteins involved in water reabsorption in the colon and result in excessive diarrhea. Emesis, or vomiting, is elimination of food by forceful expulsion through the mouth. It is often in response to an irritant that affects the digestive tract, including but not limited to viruses, bacteria, emotions, sights, and food poisoning. This forceful expulsion of the food is due to the strong contractions produced by the stomach muscles. The process of emesis is regulated by the medulla. Digestion begins with ingestion, where the food is taken in the mouth. Digestion and absorption take place in a series of steps with special enzymes playing important roles in digesting carbohydrates, proteins, and lipids. Elimination describes removal of undigested food contents and waste products from the body. Symptoms may begin as early as infancy. They include:. The body needs carbohydrates to function properly.
