ANATOMY

Detailed explanation-1: -Lipids are broken down into fatty acids, proteins into amino acids, and carbohydrates into glucose.

Detailed explanation-2: -Lipids are hydrolysed by lipases. Lipases break down lipids into fatty acids and glycerol. They are made in the pancreas and secreted into the small intestine.

Detailed explanation-3: -The amino acid-containing phosphatidylserine is a major lipid in eukaryotic membranes but in most bacteria it occurs only as a minor biosynthetic intermediate. In some bacteria, the anionic glycerophospholipids phosphatidylglycerol and cardiolipin can be decorated with aminoacyl residues.

Detailed explanation-4: -During digestion, proteins are broken down into amino acids through hydrolysis. The amino acids dissolve in our blood and are carried to tissues and organs.
