homocystine (ho·mo·cys·tine) (hoČmo-sisąt[emacr]n) a disulfide homologous with cystine and formed by oxidation and subsequent condensation of two molecules of homocysteine. It is a source of sulfur in the body.
homocysteine (ho·mo·cys·te·ine) (hoČmo-sisąte-[emacr]n) a sulfur-containing amino acid homologous with cysteine and produced by demethylation of methionine. It can serve as an intermediate in the biosynthesis of cysteine from methionine via cystathionine or can be remethylated to methionine.
