|
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 |
