Document Summary
Bc1502 introduction to cell and molecular biology. Isoforms same formula, but distinct configurations (different molecule: structural isomers. Carbon that a functional group is attached to differs: stereoisomers. The order of attachment of different molecules to a given carbon: monosaccharide rings. Ring form is the monomer of the carbohydrate polymer b, disaccharides. Made through a dehydration reaction between 1 carbon of a monosaccharide and the 4 carbon with another monosaccharide. Maltose (1 2, 1 6, 1 3 linkages also common: polysaccharides. Linear or branched chain of monosaccharides in a polymer. Used for energy storage and structural molecules a. i. Has the classic alpha 1-4 linkage a. ii. Branches being formed via beta 1-6 linkages a. iii. Linear, but has a beta 1-4 linkage. Animals can"t break down cellulose: they don"t have the enzymatic ability to do so. Plants can build cellulose and break them down: has to do with the stereoisomer nature a. iv.
