Homework Answers
1] Gel filtration chromatography is a technique used to isolate proteins, peptides on the premise of molecular weights.
2] amphiphilic or amphipathic. Phospholipids and glycolipids have both hydrophilic and hydrophobic regions.
3] Aspartic acid has least pKa value with side chain group. the value is 3.65
4] disulfide bonding between side chains of cysteines. otherwise, it is a covalent sulfur-sulfur bond.
5] mevalonate
6] the mitochondrial matrix.
7] hydrolysis.
