Question

Fill in the blanks using (fatty acids, glycerol, sphingolipids, steriods, glycolipids, glycerophospholipid, triacylglycerols.)

Compounds that contain a fused ring system are called __________. These have three 6-membered rings and one 5-membered ring. Some of these compounds are found in biological membranes. _________ are the building blocks for many lipids, and they generally contain an even number of carbon atoms and an unbranched hydrocarbon chain. ________ are formed when a carbohydrate is glycosidically linked to a hydroxyl group of a lipid. Examples include gangliosides and cerebrosides. These are found in biological membranes. ________ are the storage form of lipids, accumulating in adipose tissue, and they can be used as metabolic fuel. These compounds have a polar part, made of three ester groups, and a nonpolar fatty acid tail. They behave as all nonpolar. ________ are made up of a long-chain amino alcohol joined, either by a glycosidic linkage and a phosphodiester linkage, to a fatty acid. These do not contain ______. They are abundant in the nervous system. When glycerol is esterfied to two fatty acids and a phosphoric acid molecule a _____ is formed. These are found in biological membranes.

Answer 1

Compounds that contain a fused ring system are called steriods. These have three 6-membered rings and one 5-membered ring. Some of these compounds are found in biological membranes. fatty acids are the building blocks for many lipids, and they generally contain an even number of carbon atoms and an unbranched hydrocarbon chain. glycolipids are formed when a carbohydrate is glycosidically linked to a hydroxyl group of a lipid. Examples include gangliosides and cerebrosides. These are found in biological membranes. triacylglycerols are the storage form of lipids, accumulating in adipose tissue, and they can be used as metabolic fuel. These compounds have a polar part, made of three ester groups, and a nonpolar fatty acid tail. They behave as all nonpolar. sphingolipids are made up of a long-chain amino alcohol joined, either by a glycosidic linkage and a phosphodiester linkage, to a fatty acid. These do not contain glycerol. They are abundant in the nervous system. When glycerol is esterfied to two fatty acids and a phosphoric acid molecule a glycerophospholipid is formed. These are found in biological membranes.
