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: -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-3: -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-4: -Sulfur is essential to all living things. It is taken up as sulfate from the soil (or seawater) by plants and algae. It is used to make two of the essential amino acids needed to make proteins. It is also needed in some co-enzymes.
