MED Lecture Notes - Lecture 1: Smokeless Powder, Sphingolipid, Monounsaturated Fat
Document Summary
Lipids any substance that is water insoluble. e. g. triacylglycerol (tag), cholesteryl ester, etc. Intro/review of lipid chem: amphipathic has both polar and nonpolar components, not all lipids are non-polar; some are amphipathic in nature e. g. phospholipids and sphingolipids. In terms of structure: linear/open chain: fatty. Leukotrienes, and thromboxanes). (e. g. prostaglandins, and: cyclic: cholesterol, steroid, bile acids, Fatty acids (fa) has a non-polar hydrocarbon chain and a polar carboxylic carbon which makes them amphipathic and are classified based on the presence or absence of double bond: saturated fa: if there is no double bond present. Classified as short, medium, and long chain fa. o short chain: 2 to 4 carbons o e. g. monounsaturated fa o medium chain: Short and medium chains differ from long chain based on metabolism. Short a nd medium chain: directly absorbed in the small intestine. Long chain: transported to the lymphatic system via chylomicrons. Unsaturated fa if there is a presence of double bond;
