Question

1. It is your job to design hydrophobic a-amino acids subject to the rules for the R groups (not Ca nor carbonyl C) of (1) no more than 4 carbons, (2) any number of hydrogens, (3) no N, S, O or other non-carbon or non-hydrogen atoms, and (4) all saturated bonds. Four of the possible a-amino acids (not a-imino acids) are already found among the common amino acids. Give their common names and structural formulas. (0.25 pt/per AA) 2. Subject to these rules what other a-amino acids are possible? Give the proper IUPAC names and structural formulas for up to 8 of these. I have found 17 possible a-amino acids. (0.25 pt/per AA)

Explanation / Answer

1) Hydrophobic amino acids with 4 carbons and saturated bonds are - Alanine, valine, leucine and isoleucine
