Amino acids Flashcards
Histidine
Basic (N+)
Lysine
Basic (N+)
Arginine
Basic (N+)
Aspartate
Acidic (COO- in R group)
Glutamate
Acidic (COO- in R group)
Threonine
Polar but uncharged (OH group)
Serine
Polar but uncharged (OH group)
Cysteine
Polar but uncharged (SH group) Makes disulfide bonds
Asparagine
Polar but uncharged (Amide, or NH2 and O group)
Glycine
Nonpolar (R = Hydrogen)
Glutamine
Polar but uncharged (Amide, or NH2 and O group)
Alanine
Nonpolar (R = CxHx)
Proline
Nonpolar (R = CxHx, R bonded to Amino group)
Valine
Nonpolar (R = CxHx)
Leucine
Nonpolar (R = CxHx)
Isoleucine
Nonpolar (R = CxHx)
Methionine
Nonpolar (Has a S in a CxHx chain)
Phenylalanine
Nonpolar (Aromatic ring)
Tyrosine
Nonpolar (Aromatic ring)
Tryptophan
Nonpolar (Aromatic ring)
How do you add an amino acid onto a polypeptide chain or onto a MET?
Add onto the C-terminus of the chain
Which amino acids have an OH group, and why is that important?
Serine, Threonine, Tyrosine
Hydroxyl groups are a common target for the addition of other molecules (phosphorylation or adding phosphates)
How to remember basic amino acids
His LiAr is basic (Hystidine, Lysine, Arginine)
How to remember acidic amino acids
Acids ate (Glutamate, Aspartate)
