Chapter 10

fatty acids

-building blocks for many lipids -generally contain an even number of carbon atoms and an unbranched hydrocarbon chain

steriods

-compounds that contained a fused ring system -have three 6-membered rings and one 5-membered ring -some of these compounds are found in biological membrane

glycolipids

-formed when a carbohydrate is glycosdically linked to a hydroxyl group of a lipid -ex. gangliosides and cerebrosides

sphingolipids

-made up of a long-chain amino alcohol joined, either by a glycosidic linkage or a phosphodiester linkage to a fatty acids

triacylglycerols

-storage form of lipids, accumulating in adipose tissue -can be used as metabolic fuel -has a polar part, made of 3 ester groups and a nonpolar fatty acid tail

sphingolipids do not contain

glycerol

when glycerol is esterified to two fatty acids and a phosphoric acid molecule a ________ is formed. these are found in biological membrane

phosphoacylglycerol
