Question Answer
Full Name: Glycine 3 letter code: Gly 1 Letter Code: G -Simplest amino acid, nonpolar - Side Chain = H = Hydrophobic R group
Full Name: Alanine 3 letter code: Ala 1 Letter code: A Side chain = Methyl group = Hydrophobic R group
Full name: Phenylalanine 3 letter code: Phe 1 letter code: F -includes a phenyl ring on an Ala residue - Hydrophobic R group
Full name: Valine 3 letter code: Val 1 letter code: V -hydrophobic R group
Full Name: Leucine 3 letter code: Leu 1 letter code: L -has an extra methylene (-CH2-) group than Val -has the same formula as Ile but arranged differently. -Hydrophobic R group
Full name: Isoleucine 3 letter code: Ile 1 letter code: I - has the same formula as Leu but arranged differently -Hydrophobic R group
Full name: Methionine 3 letter code: Met 1 letter code: M - 1 of 2 amino acids with sulfur in its R group - Hydrophobic R group
Full Name: Tryptophan 3 letter code: Trp 1 letter code: W - only amino acid with a fused ring system -hydrophobic R group -Absorbs UV light at 280nm (can use Beer's law)
Full name: Proline 3 letter code: Pro 1 letter code: P - only amino acid whose side-chain loops back onto its backbone --induces kinks in a polypeptide sequence -Hydrophobic R group
Full name: Cysteine 3 letter code: Cys 1 letter code: C -2 of 2 with sulfur in the side chain. the Cys residues can form a disulfide bond - disulfide bonds facilitate crosslinking -Polar uncharged, hydrophilic R goup
Full name: Serine 3 letter code: Ser 1 letter code: S - Has a hydroxyl group in the R, side chain -(-OH-) groups are prominent nucleophiles in biochemical reactions -Other proteins can covalently bond to proteins via -OH group - Polar uncharged, Hydrophilic R, side group
Full name: Threonine 3 letter code: Thr 1 letter code: T -Has a hydroxyl group in the R, side chain -(-OH-) groups are prominent nucleophiles in biochemical reactions -Other proteins can covalently bond to proteins via -OH group - Polar uncharge, RHydrophilic R, Side group
Full name: Tyrosine 3 letter code: Tyr 1 letter code: Y -a derivative of Phe; differs by an -OH group -Phe and Tyr are precursors of amino acid derivative that are neurotransmitters - Polar uncharged, hydrophilic R, side group
Full name: Asparagine 3 letter code: Asn 1 letter code: N -Has 1 methylene groups -polar uncharged, Hydrophilic R, Side group
Full name: Glutamine 3 letter code: Gln 1 letter code: Q - has 2 methylene group -polar uncharged, Hydrophilic R, side group
Full name: Histidine 3 letter code: His 1 letter code: H -has a 5 membered ring system with N's. -can be charged at certain (low pH) values
Full name: Lysine 3 letter code: Lys 1 letter code: K - has a long side chain with a positively charged amine group -hydrophilic R, side group
Full name: Arginine 3 letter code: Arg 1 letter code: R - Long side chain with a positively charged amine group - hydrophilic R, side group
Full name: Aspartate 3 letter code: Asp 1 letter code: D - in the side chain there a carboxylate group -negatively charged, hydrophilic R, side group -analogous to Asn And Gln (both have amine groups)
Full name: Glutamate 3 letter code: Glu 1 letter code: E in the side chain there a carboxylate group -negatively charged, hydrophilic R, side group -analogous to Asn And Gln (both have amine groups) - has 1 more methylene than Asp.
