Digestion Of Nutrients Flashcards

Lipids are organic compounds comprising fatty acids, which are insoluble in water. The insoluble property of lipids makes the digestion and absorption of fats a complicated process. The first thing it does is detoxify the amino acids. There could be toxins that came in with the protein when it was first consumed.

Diets high in animal proteins cause increased excretion of calcium which can lead to osteoporosis. People who consume high levels of dietary protein may be preventing adequate dietary intake of other essential nutrients. A.) Carbohydrate absorption occurs primarily in the large intestine. B.) Carbohydrate digestion begins in the mouth with salivary amylase. C.) Carbohydrates are fully digested after passage through the stomach . D.) Bile salts from the gall bladder are essential to the digestion of carbohydrates.

For protein digestion, most of proteases are secreted in inactive forms called pro-enzymes. If they were synthesized in active forms, they would have hydrolysed cellular and extracellular proteins of the organism itself. Inactive pro-enzymes are activated at the sites of their actions by specific proteases or by optimal pH changes. Lipids, or fat, go undigested in your digestive tract until they reach your small intestine, where they meet bile. Bile contains bile salts, which act as an emulsifier of lipids.

Nutrients that the small intestine often has trouble absorbing can be macronutrients , micronutrients , or both.

C.) Bile salts from the pancreas are essential to the digestion of fats d.) Free fatty acid absorption occurs in the small intestine. The amino acids that leave the small intestine cannot go directly into the body’s circulation without a stop by the liver first. Instead, capillaries are all around the small intestine. As those amino acids cross through the small intestine, they enter the capillaries. The capillaries turn into venules and then the hepatic portal vein.

Maltase is an enzyme that breaks down maltose into glucose. Once proteins are denatured in the stomach, the peptide bonds linking amino acids together are more accessible for enzymatic digestion. That process is started by pepsin, an enzyme that is secreted by the cells that line the stomach and is activated by hydrochloric acid. Pepsin begins breaking peptide bonds, creating shorter polypeptides.

Rennin is secreted in an inactive form, prorennin,which is transformed into active rennin in the acidic medium. Rennin converts casein into paracasein, leading to milk coagulation. To break a protein down into its amino acids you will need enzymes.

Which of the following enzymes is important for breaking down protein? It is secreted by the pancreas and works in the small intestine. Carbohydrate digestion starts in mouth by the enzyme amylase present in the saliva. Food enters into the stomach where the complex protein is digested into the simple protein of dipeptides by pepsin.

This allows for maximum absorption of amino acids and other nutrients. People who cannot produce enzymes will often consume commercial preparations of proteases, lipases, and amylase. These products are available as liquids or powders and are taken by mouth or inserted into the skin. There have been reports of people who misuse protease inhibitors showing up on drug tests positive for drugs other than those they took. Be sure to read labels and follow directions carefully when using any product containing enzymes. Unless you are eating it raw, the first step in digesting an egg is chewing.

Dietary proteins are, with very few exceptions, not absorbed. Rather, they must be digested into amino acids or di- and tripeptides first. The stomach muscles churn and mix the food with digestive juices that have acids and enzymes, breaking it into much smaller, digestible pieces. An acidic environment is needed for the digestion that takes place in the stomach. Protein digestion and fermentation in the large intestine.
