Unformatted text preview: PB Part B. Biological Molecules – Structure and Function Biological Molecule What is/are their function(s)? Monosaccharide Elemental formula of simple monosaccharides is CxH2xOx, where x≥3. In other words monosaccharides are made of C, H & O in 1:2:1 ratio and with at least 3 carbons. Hydroxyl and carbonyl (C=O) functional groups Major source of energy for cells. e.g., glucose & fructose Disaccharide Two monosaccharides combined through glycosidic (either α-1,4 or β-1,4) linkages/ Two mono sachharides held together by a covalent bond. glycosidic linkage: C-O-C. Hydroxyl functional group. Nutritional source of monosaccharides. Source of energy. Glycerol A three carbon alcohol with the molecular formula: C3H8O3 Combines with fatty acids to make fat, the structural backbone of mono-, di-, and triglycerides and phospholipids Saturated Fatty Acid A long hydrocarbon...
