Document Summary

Hydroxyl: -oh (may be written ho-) *alcohols* (their specific names usually end in ol. : ec. Carbonyls: > c = o ketones- carbonyl group is within a carbon skeleton. Aldehydes- carbonyl group is at the end of the carbon skeleton. Isomers are molecules with the same molecular formula but different chemical structure: ex. Glycine, acts as a base and can pick up h+ ions from a surrounding solution (water, in living organisms). These are found in cells in ionized form: ex. Cysteine, two sulfhydryl groups can react, forming a covalent bond, s- . Lots of energy is needed to break it down: dehydration removes a water molecule to form a new bond.

Cows use microbes to help metabolize cellulose to glucose: modified and complex cho, carbohydrate with amino acid, n-acetyl glucosamine, tough because of h bonding, ex. Exoskeleton: carbohydrate with protein units, glycoproteins, ex.
