Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Lipids can be digested into what smaller subunits?
A
nucleic acids
B
amino acids
C
fatty acids
D
glucose
Explanation: 

Detailed explanation-1: -Pancreatic enzymes called lipases then hydrolyze the dispersed fats to give monoglycerides and free fatty acids. These products are absorbed into the cells lining the small intestine, where they are resynthesized into triglycerides.

Detailed explanation-2: -Final answer:-Glycerol and fatty acids are the sub-units of lipids.

Detailed explanation-3: -There are three important families of lipids: fats, phospholipids and steroids. Fats are large molecules made of two types of molecules, glycerol and some type of fatty acid. The fatty acid has a long chain of carbon and hydrogen, usually referred to as the hydrocarbon tail, with a carboxyl group head.

Detailed explanation-4: -As the smallest unit of lipids is a glycerol, whereas, the amino acid is the smallest unit for protein, there are two questions (1) identify which molecule connects together two amino acids and (2) explain if there is a need to connect two different lipids, explain why.

Detailed explanation-5: -The human fatty acid synthase (FAS; EC 2.3. 1.85), like other animal synthases, catalyzes the synthesis of long-chain fatty acids from acetyl-CoA, malonyl-CoA, and NADPH. The native enzyme has a molecular weight of 544, 000 and is composed of two identical subunit proteins (1, 2).
