Document Summary
* properties of water: excellent solvent: dipoles of h2o break up charged ionic molecules, high heat capacity: heat capacity is the degree in which a substance changes temp in response to gain/loss of heat. Starch: a polymer of -glucose molecules; store energy in plant cells. Glycogen: a polymer of -glucose molecules; store energy in animal cells. (differ in polymer branching). Cellulose: a polymer of -glucose; structural molecules for walls of plant cells and wood. Chitin: polymer similar to cellulose; but each -glucose has a nitrogen-containing group attached to ring. Storage protein: casein in milk, ovalbumin in egg whites, and zein in corn seeds. * enzymes: atp contains ribose instead of deoxy-ribose. Amylase catalyzes the rxn that breaks the -glycosidic bonds in starch. Catalyzes a reaction in both forward and reverse directions based on [substrate]. Efficiency is determined by temp and ph. Cofactors are nonprotein molecules that assist enzymes.
