BIOMOLECULES AND ENZYMES

Detailed explanation-1: -To obtain energy from fat, triglycerides must first be broken down by hydrolysis into their two principal components, fatty acids and glycerol. This process, called lipolysis, takes place in the cytoplasm.

Detailed explanation-2: -Because one triglyceride molecule yields three fatty acid molecules with as much as 16 or more carbons in each one, fat molecules yield more energy than carbohydrates and are an important source of energy for the human body.

Detailed explanation-3: -Lipids are used as energy storage via fatty acids. Fatty acids are composed of carboxylic acids attached to long chains of hydrocarbons. These are carbons that can range from 4 to 36 carbons.

Detailed explanation-4: -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.
