Amino Acids

Gly
Glycine. nonpolar. hydrophobic. only non-chiral amino acid.
Ala
Alanine. nonpolar. hydrophobic. R=methyl
Pro
Proline. nonpolar. hydrophobic. aliphatic. cyclic “imino acid.” no free hydrogen on N for bonding.
Val
Valine. nonpolar. hydrophobic. Think V!
Leu
Leucine. nonpolar. hydrophobic
Iso
Isoleucine. nonpolar. hydrophobic. 2 chiral carbons.
Met
Methionine. nonpolar. Very hydrophobic. Sulfer containing.
Phe
Phenylalanine. nonpolar. hydrophobic. aromatic.
Tyr
Tyrosine. polar. both hydrophobic and hydrophillic but mostly hydrophilic. aromatic. H-Bonding
Try
Tryptophan. nonpolar. hydrophobic. aromatic. H-bonding
Asp
Aspartate. acid. (-) present as conjugate base. Carboxyl group sometimes act as nucleophiles
Glu
Glutamate. acid. hydrophilic. (-) present as conjugate base. Carboxyl group sometimes act as nucleophiles
Lys
Lysine. basic. hydrophilic nitrogenous base. (+). diamino acid
Arg
Arginine. most basic amino acid. hydrophilic nitrogeneous base. (+). guianidinium ion always protonated.
His
Histadine. basic. hydrophilic nitrogenous base. (+). imidazole ring. only amino acid that can function as buffer.
Ser
Serine. polar. (neutral).
Thr
Threonine. polar. (neutral).
Cys
Cysteine. polar. hydrophilic. sulfer containing – sulfhydryl.
Asn
Asparagine. polar. (neutral)
Gln
Glutamine. polar. (neutral)
zwitterion
Amino Acid in water has (+)N and (-)C ends. Charge depends on R groups.
