Cyclic
Proline
Aromatics
Phenylalanine, Tyrosine, Tryptophan
Aliphatic hydroxyl
Serine, Threonine
Carboxamides
Asparagine, Glutamine
Sulfhydryl
Cysteine
Basic
Lysine, Arginine, Histidine, Guanadinium, Imidazole
Acidic carboxylates
Aspartate, Glutamate
Characts of Alaphatics:
-fold with hydrophobics on inside
-Insides of proteins
-valine, leucine, isoleucine, and methionine
Glycine characts
-R group of "H"
-Only achiral amino acid, and therefore there is no D/L configs
Cyclic characts
often found in bends in DNA
proline
Aromatic characters
-rings
-all have benzene-like structures
bulky
encroach on the space of other amino acids
phenylalanine, tyrosine, tryptophan
Aliphatic hydroxyl characts
hydrophilic
outside of protein
amino acid to which phosphates get linked
Sulfhydryl characts
cysteine forms a disulfide bond, which is covalent
Basic characts
lose protons off of side chains only at high pHs
exception: Histidine, which loses proton at about 6
Acidic characteristics
R groups lose protons at low pH
Carboxamide characts
related to the acidic
do not ionize under certain conditions
