Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which enzyme acts on fats? What are the final products from digestion of fats?
A
Protease/amino acids
B
Amylase/polypeptide
C
Maltase/glucose and maltose
D
Lipase/fatty acids and glycerol
Explanation: 

Detailed explanation-1: -lipase, any of a group of fat-splitting enzymes found in the blood, gastric juices, pancreatic secretions, intestinal juices, and adipose tissues. Lipases hydrolyze triglycerides (fats) into their component fatty acid and glycerol molecules.

Detailed explanation-2: -The end products of fat digestion are fatty acids and glycerol. Bile is a green fluid secreted by the liver that helps in the digestion of fats.

Detailed explanation-3: -Lipases are known to carry out the breakdown of fat molecules within the food. These act on the emulsified or fragmented fat to break them down into simpler substances for proper absorption. The end product formed due to the digestion of fat is fatty acids and glycerol.

Detailed explanation-4: -Lipase is an enzyme the body uses to break down fats in food so they can be absorbed in the intestines. Lipase is produced in the pancreas, mouth, and stomach.

Detailed explanation-5: -Lipases (triacylglycerol hydrolases E.C. 3.1. 1.3) are enzymes that catalyze the hydrolysis of triacylglycerols (TAGs) to glycerol and fatty acids (FAs). Lipases, together with amylases and proteases, constitute the three major known digestive enzymes.
