Features
- Single letter code = D
- Three letter code = Asp
- Codons = GAU, GAC
- Has a negatively charged hydrophilic side chain.
Name the Amino Acid shown below:
Cysteine
Features
- Single letter code = C
- Three letter code = Cys
- Codons = UGU, UGC
- It is a special case amino acid
Name the Amino Acid shown below:
Glutamic Acid
Features
- Single letter code = E
- Three letter code = Glu
- Codons = GAG, GAA
- Has a negatively charged hydrophilic side chain.
Name the Amino Acid shown below:
Glutamine
Features
- Single letter code = Q
- Three letter code = Gln
- Codons = CAA, CAG
- It has a polar but uncharged side chain.
Name the Amino Acid shown below:
Glycine
Features
- Single letter code = G
- Three letter code = Gly
- Codons = GGU, GGC, GGA, GGG
- It is the simplest amino acid of the 20 amino acids since its side chain only contains a single H atom.
- Since it’s side chain only contains a single H atom, it is the only amino acid with a central carbon that is not a chiral carbon.
- It is a special case amino acid.
Name the Amino Acid shown below:
Histidine
Features
- Single letter code = H
- Three letter code = His
- Codons = CAC, CAU
- Has a positively charged hydrophilic side chain
Name the Amino Acid shown below:
Isoleucine
Features
- Single letter code = I
- Three letter code = Ile
- Codons = AUA, AUC, AUU
- Has a non-polar hydrophobic side chain.
Name the Amino Acid shown below:
Leucine
Features
- Single letter code = L
- Three letter code = Leu
- Codons = CUU, CUC, CUA, CUG
- Has a non-polar hydrophobic side chain.
Name the Amino Acid shown below:
Lysine
Features
- Single letter code = K
- Three letter code = Lys
- Codons = AAA, AAG
- Has a positively charged hydrophilic side chain.
Name the Amino Acid shown below:
Methionine
Features
- Single letter code = M
- Three letter code = Met
- Codons = AUG
- Has a non-polar hydrophobic side chain.
Name the Amino Acid shown below:
Phenylalanine
Features
- Single letter code = F
- Three letter code = Phe

Name the Amino Acid shown below:
Proline
Features
- Single letter code = P
- Three letter code = Pro
- Codons = CCU, CCC, CCA, CCG
- It is a special case amino acid.
- Ignore the negative charge next to the H2 N group because that negative charge belongs to the COOH group of glycine.
