Amylose is a glucose polymer with a(14) linkages. The end of the polysaccharide with an anomeric C1 not involved in a glycosidic bond is called the reducing end Slide 10: Amylopectin is a glucose polymer with mainly a(14) linkages, but it also has branches formed by a(16) linkages. Branches are generally longer than shown above. The branches produce a compact structure & provide multiple chain ends at which enzymatic cleavage can occur AMYLOPECTIN : AMYLOPECTIN GLYCOGEN : GLYCOGEN GLYCOGEN : GLYCOGEN ANIMAL STARCH PRESENT IN LIVER, MUSCLES, BRAIN FOUND IN YEAST AND FUNGI The role of cellulose is to impart strength and rigidity to plant cell walls : The role of cellulose is to impart strength and rigidity to plant cell walls ß-GLUCOSE UNITS IMPORTANCE OF CARBOHYDRATES : IMPORTANCE OF CARBOHYDRATES IMPORTANCE : IMPORTANCE ESSENTIAL FOR LIFE MAJOR PORTION OF OUR FOOD HONEY- INSTANT SOURCE OF ENERGY STORAGE- STARCH(PLANTS) AND GLYCOGEN(ANIMALS) CELL WALL OF BACTERIA AND PLANTS-PROTECTION IMPORTANCE : IMPORTANCE FURNITURE FROM CELLULOSE CLOTHES (COTTON FIBRES)—CELLULOSE RAW MATERIAL FOR TEXTILE INDUSTRIES,BREWERIES D-RIBOSE AND 2-DEOXY-D-RIBOSE---PRESENT IN NUCLEIC ACIDS FOUND IN ECOSYSTEM IN COMBINATION WITH MANY PROTEINS AND LIPIDS.
