BSC 2010C Lecture Notes - Lecture 4: Coronary Artery Disease, Dehydration Reaction, Covalent Bond
Document Summary
Macromolecules- a giant molecule formed by the joining of smaller molecules, usually by a dehydration reaction. Varies in # of carbons & in position of carbonyl. Depending on location of carbonyl group, a sugar is either an aldose or a ketose. Glycoside linkage - a covalent bond formed b/w two monosaccharides by a dehydration reaction. Polysaccharides- a polymer of many monosaccharides formed by dehydration reactions. Starch- a storage polysaccharide in plants, consisting entirely of glucose monomers joined by glycosidic linkages. Glycogen- an extensively branched glucose storage polysaccharide found in the liver and muscle of animals; the animal equivalent of starch. Others serve as building material for structures that protect the cell or the whole organism. Cellulose- a structural polysaccharide of plant cell walls, consisting of glucose monomers joined by glycosidic linkages. Carbohydrate macromolecules are polymers called polysaccharides, composed of many sugar building blocks. Glycerol molecule + 3 fatty acids; also called a triacylglycerol or triglyceride.
