In human body, the role of bile salts in digestion is to

• B. emulsify fats and facilitate their absorption.
• C. aid in the break-up of proteins into amino acids and their absorption.
• D. stimulate the pancreas to release its enzymes.

Answer 1

Answer: (B)

Bile secreted by the liver is an alkaline, yellowish-green, juice that has no enzyme. It is formed of water, sodium bicarbonates, bile pigments (bilirubin and biliverdin), and two bile salts (sodium glycocholates and sodium taurocholate). Fats are finally emulsified in small intestine by action of bile salts.
