Document Summary

Lipids usually have a fatty acid attached to them. Unsaturated fatty acids have a kink or bend in the structure, do not pack tightly together, have a double bond somewhere in them. A triglyceride is also known as fat, is a nontoxic way to store fatty acids, and has three fatty acids attached. During digestion, fat droplets in food or solubilized and made smaller by secretion of bile acids and salts into the small intestine. Enzymes that hydrolyze sized lipids= pancreatic lipase, phospholipase a2, cholesterol. What is found in a typical chylomicron or very low-density lipoprotein particle in blood: phospholipids, apob protein, cholesteryl ester, triglycerides. Chylomicron is the lipoprotein particle that is assembled in the enterocyte and delivers dietary fat throughout the body. Album carries a following around the body: free fatty acids. Excess and unused fatty acids carried by albumin are taken up by the liver an reassembled into triglycerides.
