Document Summary

Pentoses (c5 h10 o6: xylose and arabinose, fructose, mannose. Most important vehicle for carbohydrate transport in body fluids and intracellular metabolism in animals. Composes of two monosaccharides with an or linkages depending on the isometric form of the monosaccaride constituents. Cellobiose: consists of two glucose units with a beta linkage, product of hydrolysis of cellulose does not occur naturally in free form. Lactose: consists of glucose and galactose with beta linkage, principle carbohydrate in milk; unique product of mammary gland. Lecture 13: carbohydrates (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) Polymers consisting of large number of pentose or hextose (usually glucose) units. Consists of large chains of glucose units with repeating alpha linkages. Different chemical forms include amylose (mainly linear structure) and amylopectin (branching structure) Major carbohydrate storage in many plants, especially in seeds (e. g. cereal grains: glycogen, cellulose. Highly branched chains of glucose units with alpha linkages. Major carbohydrate storage form in animal tissues, especially in liver and muscle.
