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: -Like sugars and amino acids, the catabolic pathways of lipids are also connected to the glucose catabolism pathways. The lipids that are connected to the glucose pathways are cholesterol and triglycerides.

Detailed explanation-4: -Lipids are large molecules and generally are not water-soluble. Like carbohydrates and protein, lipids are broken into small components for absorption.
