Which of the following describes the function of the enzyme Phospholipase A2?

  1. It digests dietary cholesterol esters into free fatty acid chains
  2. It cleaves the fatty acid from the second position of a phospholipid
  3. It breaks down dietary starch into the trisaccharide maltotriose
  4. It converts the inactive zymogen pepsinogen into active pepsin in the duodenum
Show answer and explanation

Correct answer: It cleaves the fatty acid from the second position of a phospholipid

Phospholipase A2 is a pancreatic enzyme activated by trypsin. It targets phospholipids such as lecithin, removing a fatty acid to produce lysophospholipids, which are important components of micelles.
