HUMAN NUTRITION

Detailed explanation-1: -Dietary lipids are hydrolyzed in the intestinal lumen and products are taken up by enterocytes . Enterocytes re-synthesize lipids and package them into chylomicrons for secretion. These lipoproteins are hydrolyzed during circulation and products are taken by peripheral tissues.

Detailed explanation-2: -Lipids are available to the body from three sources. They can be ingested in the diet, stored in the adipose tissue of the body, or synthesized in the liver. Fats ingested in the diet are digested in the small intestine.

Detailed explanation-3: -Nearly all dietary lipid is absorbed by the enterocytes of the small intestine, packaged in triglyceride-carrying particles known as chylomicrons, and transported from the intestine to the blood stream via the lymphatic system [3].

Detailed explanation-4: -Once inside the intestinal cell, short-and medium-chain fatty acids and glycerol can be directly absorbed into the bloodstream, but larger lipids such as long-chain fatty acids, monoglycerides, fat-soluble vitamins, and cholesterol need help with absorption and transport to the bloodstream.
