Complex carbohydrates that serve as energy storage molecules in animals and plants must be easily digestible so that the molecul
e can release monomers which contain stored energy. Enzymes responsible for catalyzing they hydrolysis reactions that release carbohydrate monomers are only able to break alpha bonds. Based on this knowledge, which of the carbohydrate polymers below would you expect to be made from alpha bonds? A. cellulose B. peptidoglycan C. starch D. chitin
starch is a polysacharride made up of amylose (unbranched molecule) and amylopectin (branched molecule) both of alpha glucose.
Alpha glucose have OH -hydroxyl group below the first carbon in the ring structure.
these alpha carbons of the amylose and amylopectinc are fused by condensation reaction to form alpha glycosidic bonds.
for example the 1,4, alpha glycosidic bonds in starch is formed between the alpha cabon 1 on one ring structure of glucose and carbon 4 of the next carbon in amylose .it is long coiled to give a compact structute to starch. While the shorter 1, 6 alpha glycosidic bond added to the relatively large grains of starch.
Our bodies produce an enzyme called lactase. This enzyme helps our bodies digest lactose (a sugar found in milk). As we age, the amount of lactase our bodies produce decreases. Some people don’t produce as much as others. If you are lactose intolerant, it means your body doesn’t produce a lot of lactase. One option is to drink milk with lactase added to it. Example: Lactaid
