Write a general formula for a-amino acids and draw the actual formulas for any two named amino acids you choose. What is a peptide bond? Show, with formulas, how such a bond forms a link between two amino acids. Distinguish between L- and D-amino acids. Note: You must draw the actual formula, not just write them.
1. a physical structure representing a general amino acid;
2. the drawn structures of two different amino acids;
3. a drawing of the reaction of the formation of a peptide bond;
4. a D-and-L amino acids and how they are named as such.
