c. a widley used inhibiotr of protein synthesis
d. a byproduct formed during the degradation of proline
e. an amino acid found in most proteins.
Which of the following amino acids contains a secondary amine?
a. histidine
b. serine
c. glutamate
d. arginine
e. proline
Which amino acid is most likely to have a net positive chare at pH 7?
a. aspartic acid
b. glutamine
c. histidine
d. lysine
Solution
1. a. formed by the post-translational modification of a protein
Hydroxyproline formed by hydroxylation of proline that happens after translation in lumen of endoplasmic reticulum.
2. proline
Proline is the amino acid containing secondary amine
3. Lysine : as it has basic sided chains
