A chemical compound that consists of two cysteine molecules joined by a disulphide bond. 10, record 1, English, - cystine
Record number: 1, Textual support number: 1 CONT
Cystine, the oxidized form of cysteine, plays a special role in protein structure since its disulfide group serves as a covalent cross-link between two polypeptide chains or between two points in a single chain. Disulfide cross-links can be cleaved by the action of reducing agents, e.g., mercaptoethanol, which yields two molecules of cysteine from cystine. Cystine can also be oxidized by such agents as performic acid, to yield two molecules of cysteic acid. 11, record 1, English, - cystine

Record number: 1, Textual support number: 1 DEF
Acide aminé, comportant un pont disulfure, formé par l'union de deux molécules de cystéine, sous l'effet d'une oxydation. Elle joue un rôle d'agent de réticulation dans la structure protéique. 5, record 1, French, - cystine
Record number: 1, Textual support number: 1 CONT
Il y a 3 aminoacides soufrés, la méthionine, la cystéine et la cystine; mais les deux derniers sont très facilement interconvertibles par oxydation-réduction et on peut considérer qu'ils n'en forment qu'un. La méthionine est - pour le rat comme pour l'homme - un aminoacide indispensable, alors qu'il n'est pas indispensable de fournir la cystéine. Cependant, lorsqu'on donne de la cystéine, les besoins en méthionine diminuent, ce qui suggère qu'une partie de la méthionine est utilisée à former la cystéine; ceci devait être confirmé par les études faites à l'aide d'isotopes radioactifs. 6, record 1, French, - cystine
