Detailed explanation-1: -Sulfur is a component of heparin, chondroitin in bones and cartilage, thiamin, biotin, pantothenic acid, and S-adenosyl methionine (SAM-e). It also is a part of glutathione, an important antioxidant. Sources of sulfur include animal proteins, legumes, broccoli, and nuts.

Detailed explanation-2: -Methionine and cysteine are the two primary sulfur-containing amino acids in mammals. Methionine is an essential amino acid, obtained by dietary intake while cysteine is non-essential and a metabolite of methionine metabolism.

Detailed explanation-3: -Sulfur is the third most abundant mineral in your body. It is present in methionine and cysteine, which are two of the amino acids you use to make proteins. Both of these amino acids are present in your skin, hair, and nails where they help to make these tissues strong and flexible.

Detailed explanation-4: -In plants and animals, the amino acids cysteine and methionine contain most of the sulfur, and the element is present in all polypeptides, proteins, and enzymes that contain these amino acids.

Detailed explanation-5: -In fact, sulfur occurs in all the major classes of biomolecules, including proteins, sugars, nucleic acids, vitamin cofactors and metabolites, and is required by all living organisms.
