Document Summary
Biol 2960 exam 1 study guide: relationship between alcohol, aldehyde (ketone) & organic acid. Not alphabetical order = bad = reduction: lactose intolerance. As babies, we can synthesize lactase, but as we grow older, some of us lose that ability. The buildup of undigested lactose provides for the growth of a type of bacteria that possesses the enzyme b-galactosidase. This enzyme produces gas as it digests lactose, so this leads to discomfort: cellulosic ethanol. To produce glucose, cellulose can be broken down through hydrolysis by certain enzymes found the in the gut tissue and/or mircroorganisms living in the guts of wood/grass eating animals: modern hair perm. Hair is made of a protein called alpha-keratin, which is stabilized by disulfide bonds. To perm hair, one can use a reducing agent to break the disulfide bonds and enable the hair stylist to shape the hair. Afterwards, the disulfide bonds can be reconstructed using oxidizing agents such as hydrogen peroxide: scurvy.
