Question

In human body, the role of bile salts in digestion is to
a. Act as coenzyme during the digestion of carbohydrates
b. Emulsify fats and facilities that their absorption
c. Aid in the breakup of protein into the amino acid and their absorption
d. Stimulate the pancreas to released its enzyme

Answer 1

Hint: In the small intestine including cholesterol, bile acid, phospholipids that flows through the biliary tract, and bile is a complex fluid containing electrolytes, battery of organic molecules and water. The presence of bile acids which is critical for absorption food and digestion in the small intestine. On the second side numerous waste products such as bilirubin are eliminated from the body.

Complete answer:
In the liver production of the yellowish brown fluid, and bitter in tasting known as bile. In the small intestine lipid digestion occurred by the bile and stored in the gallbladder and after digestion discharged into the duodenum. 85% water, 3% pigments and 10% bile salts, 0.7% inorganic salt and 1% fats composed in it.

In the micelles bile acids are able to solubilize many lipids such as cholesterol, monoglycerides and fatty acids. That remains suspended in the water. Cholesterol breakdown in the body occurred by hepatic synthesis of bile acids and in the human body 500 mg of cholesterol converted to the bile acids and elimination of the bile in every day. And in the secretion of bile products enteric hormones play a very important role and name after the effect on the biliary system.

Bile acid is an amphipathic in nature and contains both hydrophilic and hydrophobic faces. In the hydrophilic portion amino acids are derived and in the hydrophobic region bile acids are formed.

Hence, the correct answer is option (B).

Note: On the dietary fats bile acids act as a detergent, and emulsification causes the fat globules to break down into microscopic droplets, and are emulsified into minutes. Cholesterol and potentially toxic compounds such as drug metabolites and bilirubin excrete with the help of bile salts.
