1Describe the general structure of an amino acid?
2Are L or D isomers used in proteins?Only L-isomers are used in protein chains.
3Name 5 non-polar neutral amino acids:Glycine, Alanine, Cysteine, Proline, Phenylalanine
4Name the 1 polar-neutral amino acid:Serine which contains the OH R-group
5Name two polar charged (acidic and basic) amino acids:Aspartic acid (acid - COOH)
Lysine (basic - C4H8NH2)
6What is hydroxylation?This is the process where an OH group is added to an amino acid
7What is phosphorylation?When a phosphate group (PO43- is esterified to the hydroxyl group)
8Which 3 amino acids can be phosphorylated?Serine, tyrosine and threonine.
Phosphorylation of these 3 amino acids can have a dramatic effect on protein function.
9What amino acids are hydrophilic and which ones are hydrophobic?Polar = Hydrophilic
Non-polar = Hydrophobic
(Think of it as like dissolves like)
10What bond links amino acids together?Peptide bonds
They are covalent bonds which hold amino acid residues together and are a type of condensation reaction.
11Peptides contain less than...50 amino acids
12BackboneRepeating part of polypeptide –
N-C-C-N-C-C-N-C-C-
