Document Summary

Food lectures : carbs ~sugar, lipids, proteins, amino acids. Single unit form covalent bonds with monomers and form polymers. Monomer 1 + monomer 2 = dehydration reaction = polymer. Condensation reaction occur because they are catalyzed by enzymes (enzymes. The enzyme will hold in activation site and lower the activation energy (activation energy= energy required to break bonds and re-create them) Enzymes can carry out opposite reactions as well- they break down long polymers into smaller monomers, the reaction requires the input of water. Long polymer +h2o= shorter polymer and monomer. That reaction is called a hydrolysis (this also happens in the lysomes (intracellular digestion)) Monomers of cards are called monosacrides-(single unit) Polysacride- hundreds or thousands of monosacrides linked together. Can form alpha ring or beta ring. Alpha is in starch, beta is in cellulose. * we don"t have enzymes to break down cellulose.
