Document Summary

Properties of water: cohesion: holds the molecules of water together clings to polar molecules through hydrogen bonds. Macromolecules (polymers): carbohydrates: consist of c, h and o in the 1:2:1 ratio. Lipids have a higher ratio of c and h atoms to o than carbs more bonds = more energy. Consist of oh and coh functional groups. Monomers of carbs are monosaccharides (glucose, fructose, galactose, ribose, deoxyribose) 2 monomers (disaccharides maltose, sucrose, lactose) Glycosidic linkages are found between monomers of a carbohydrate. 3-10 chains of carbs are called ogliosaccharides 3-20 chains of carbs are called polysaccharides (starch, cellulose structural support in plants, glycogen, chitin structural support in animals) Glycogen is energy storage in adipose tissue (animal fat) yields glucose after hydrolysis insoluble in water. Amylose and amylopectin is an immediate source (polysaccharide) of energy in plants. Glycogen is an immediate source of energy in animals.
