Document Summary
Cholesterol: mostly associated with problems with cardiovascular disease. Lots of ch bonds nonpolar but has polar parts. Loses the hydrogen and has a double bonded o instead of a oh. Amino acids are monomers, polypeptides are polymers. Amino group no one side, carboxyl group, and functional group (r) This functional group is extremely important (more influencing than the other monosaccharide ones) Require nitrogen to break down amino acids. Nonessential amino acids: do not need to get them from diet. 8 amino acids must come from food (essential) Need to look at side chains to figure out. If you see oh, sh, nh most likely going to be polar. Peptide bond (dehydration reaction will make the new peptide bond) At one end there is a amino group, the other has a carboxyl. Come into play when thinking about orientation. B-subunit: the part of the amino acid sequence.
