Document Summary
Lomoar cpsd| 987298: humans can break down plant starch via hydrolysis, high starch content in: potatoes & grains (wheat/corn/rice) Glycogen = storage polysaccharide in animals, made of glucose: more branched than starch , most glycogen is stored in liver and muscles cells (hydrolyze glycogen into glucose when needed) Cellulase = enzyme found in some microorganisms that hydrolyzes cellulose. Found in cows and termites (termites can produce it) . Chitin = structural polysaccharide, used by insects & crustaceans to build their exoskeleton . Humans use it to make surgical thread that decomposes after a wound heals. Almost all carbohydrates are hydrophilic (due to many hydroxyl groups) . Proteins are made from amino acids linked by peptide bonds. Diversity of proteins made up of arrangements of a common set of 20 amino acids . Amino acids = contain an amino group and a carboxyl group, both of which are covalently bonded to a central carbon atom .
