Question

What percentage of amino acids is absorbed in the small intestine?

• A. 15%
• B. 30%
• C. 100%
• D. 90-95%

Answer 1

The correct option is D 90-95%

Initiation of protein digestion starts in the stomach by pepsin but around 90-95% of protein is digested and absorbed in duodenum and jejunum of the small intestine in the form of amino acids by the action of enzymes trypsin, chymotrypsin and carboxypeptidases.

So the correct option is '90-95%'
