Q: Example for sulphur containing amino acids
  • A. Tryptophan
  • B. Cysteine
  • C. Proline
  • D. Histidine
Correct Answer: Option B - Methionine, cysteine, homocysteine and taurine are the 4 common sulfur containing amino acids, But only the first 2 are incorporate into proteins sulfur belongs to the same group in the periodic table as oxygen but is much less electronegative mainly in the liver from homocysteine derived from the transmethylation of methionine, cysteine can be endogenously synthesized our body cysteine is created from methionine, an essential amino acid.
