Detailed explanation-1: -Triglycerides are broken down to fatty acids, monoglycerides (glycerol backbone with one fatty acid still attached), and some free glycerol. Cholesterol and fat-soluble vitamins do not need to be enzymatically digested (see Fig. 5.22 below).

Detailed explanation-2: -Triglycerides are esters in which three molecules of one or more different fatty acids are linked to the alcohol glycerol; they are named according to the fatty acid components; e.g., tristearin contains three molecules of stearic acid, and oleodistearin, one of oleic acid and two of stearic acid.

Detailed explanation-3: -The stomach, liver, biliary tract, pancreas, and small intestine all participate in normal triglyceride digestion and absorption.

Detailed explanation-4: -Lipases in the cells of adipose tissues break down the triglycerides so that fatty acids can reenter the bloodstream for transport to energy-requiring tissues.

Detailed explanation-5: -Triglycerides is a fat that is made up of glycerol backbone and fatty acids units. Thus, the end product of fat digestion include fatty acid and glycerol.
