A non-essential amino acid in mammals. It contains a highly reactive hydrophobic sulfhydryl group as its sidechain. [ see schematic diagram
A nonessential amino acid but may be essential for individuals with certain diseases or nutritional concerns. Cysteine is a sulfur-bearing amino acid with antioxidant properties. It is important for keratin synthesis, a protein found in skin, hair and nails and is a component of coenzyme A and glutathione.

an amino acid that contains sulfur and is found in the protein of the hair; the bond it forms strengthens the hair.
has something to do with sulfur. NOT the same as cystine. Andy recommends a plasma cysteine test to find out if a child/adult is "high sulfur" or "low sulfur". (see http://home.earthlink.net/~moriam/ANDY_INDEX.html for further details. Look for the section about sulfur and thiols.)
amino acid that can cross link peptide chains.
amino acid which can confer stability upon a protein through sulfide bridging.
amino acid by-product of homocysteine metabolism.
A nonessential amino acid, one of the few that contains sulfur. The body uses cysteine to produce taurine, another amino acid.
Cysteine is a non-essential amino acid. As a flour improver it makes doughs more extensible and less elastic. Cysteine is made from feathers and also by synthetic means.
a sulfur-bearing amino acid that makes up part of the compound glutathione.
(as in cysteine hydrochloride) a sulfur-containing amino acid found in many proteins. Valuable as a source of sulfur in metabolism.
A nonessential, sulfur-containing amino acid converted within the body to cystine, an important constituent of hair.
A sulfur-containing nonessential amino acid.
maintains the structure of proteins in the body and can also be converted into glucose and used as a source of energy.
an amino acid, or protein building block, that is part of glutathione.
A sulphur-bearing, essential amino acid that supports activity in the catecholamine biosynthetic pathway. Cysteine also has anti-oxidant activity, directly aids in glutathione synthesis and supports both detoxification and methylation pathways.
And amino acid that is needed to produce pheomelanin.
an amino acid found in proteins that has sulfur as one of its constituent atoms.
A semi-essential amino acid.
A sulfur containing amino acid that is important for healthy skin functioning. Cysteine aids in the production of collagen and promotes proper skin elasticity and texture. Cysteine is also a powerful detoxifier of alcohol, smoke and environmental pollutants.
Cysteine is a naturally occurring, sulfur-containing amino acid that is found in most proteins, although only in small quantities. Cysteine is unique amongst the twenty natural amino acids as it contains a thiol group. Thiol groups can undergo oxidation/reduction (redox) reactions; when cysteine is oxidised it can form cystine, which is two cysteine residues joined by a disulfide bond.
