disulphidedisulfiden.

Brit.

/dʌɪˈsʌlfʌɪd/, U.S.

/daɪˈsəlˌfaɪd/

Etymology: < di- comb. form + sulphide n.

Chemistry.

A compound in which two atoms of sulphur are united with another element or a radical, as carbon disulphide, CS₂. †Formerly, a compound having one atom of sulphur united to two of another element, as disulphide of copper = cuprous sulphide, Cu₂S.

ΚΠ

1864 H. Watts Dict. Chem. II. 74 Hemisulphide of Copper, or Cuprous Sulphide, Cu⁴=Ccu²S, or Cu²S, also called Disulphide of copper.—Found native as Copper-glance.

1866 H. E. Roscoe Lessons Elem. Chem. xii. 109 When deposited from solution in carbonic di-sulphide, sulphur crystallizes in the ordinary natural or octahedral form.

1895 Edinb. Rev. Oct. 409 Carbon disulphide took it up more freely.

Draft additions March 2020

disulphide bond n. a covalent linkage between two sulphur atoms, —S—S—, which cross-links polypeptide chains in the three-dimensional structures of some proteins; also called disulphide bridge.The sulphur atoms are provided by the thiol groups of the amino acid cysteine.

ΚΠ

1934 Jrnl. Amer. Chem. Soc. 56 937/2 Cystine is reduced by sodium, in part, by sodium acting directly upon the disulfide bond.

2009 T. Shibamoto & L. Bjeldanes Introd. Food Toxicol. (ed. 2) vi. 140 Ricin is composed of two protein chains, A and B, linked by a disulfide bond.

Draft additions March 2020

disulphide bridge n. = disulphide bond n. at Additions.

ΚΠ

1932 Jrnl. Amer. Chem. Soc. 54 4396 It is thought also that where sulfhydryl groups do exist in a unit they combine with similar groups of other units to form aggregates held together by disulfide bridges and perhaps by other means.

1990 EMBO Jrnl. 9 2361/1 Hirudin consists of a polypeptide chain of 65 or 66 residues with three disulphide bridges.
