Cysteine (symbol Cys or C; [5] / ˈ s ɪ s t ɪ iː n /) [6] is a semiessential [7] proteinogenic amino acid with the formula HOOC−CH(−NH 2)−CH 2 −SH. The thiol side chain in cysteine enables the formation of disulfide bonds, and often participates in enzymatic reactions as a nucleophile. Cysteine is chiral, but both D and L-cysteine ...

Cystine is the oxidized derivative of the amino acid cysteine and has the formula (SCH 2 CH(NH 2)CO 2 H) 2.It is a white solid that is poorly soluble in water. As a residue in proteins, cystine serves two functions: a site of redox reactions and a mechanical linkage that allows proteins to retain their three-dimensional structure.
It is a homologue of the amino acid cysteine, differing by an additional methylene bridge (-CH 2-). It is biosynthesized from methionine by the removal of its terminal C ε methyl group . In the body, homocysteine can be recycled into methionine or converted into cysteine with the aid of vitamin B 6 , B 9 , and B 12 .

This Jennifer Aniston-fave serum stick is the ideal delivery system for softening fine lines, prepping skin for makeup and targeting dry patches (I've tried it — it actually blurred my wrinkles).
Cysteic acid also known as 3-sulfo-l-alanine is the organic compound with the formula HO 3 SCH 2 CH(NH 2)CO 2 H. It is often referred to as cysteate, which near neutral pH takes the form − O 3 SCH 2 CH(NH 3 +)CO 2 −. It is an amino acid generated by oxidation of cysteine, whereby a thiol group is fully oxidized to a sulfonic acid/sulfonate ...
