Detailed explanation-1: -Methionine and cysteine are the two primary sulfur-containing amino acids in mammals.

Detailed explanation-2: -General description. Cysteine is a non-essential amino acid important for making protein, and for other metabolic functions. It’s found in beta-keratin. This is the main protein in nails, skin, and hair.

Detailed explanation-3: -Methionine and cysteine are the sulphur containing amino acids.

Detailed explanation-4: -The four sulphur-containing amino acids are methionine, cysteine, homocysteine, and taurine, but only the first two are absorbed into proteins.

Detailed explanation-5: -Cysteine is one of two sulfur-containing amino acids; the other is methionine. Cysteine differs from serine in a single atom–the sulfur of the thiol replaces the oxygen of the alcohol. The amino acids are, however, much more different in their physical and chemical properties than their similarity might suggest.
