biosen.

Brit.

/ˈbʌɪəʊz/,

/ˈbʌɪəʊs/, U.S.

/ˈbaɪˌoʊs/,

/ˈbaɪˌoʊz/

Origin: Formed within English, by derivation. Etymons: bi- comb. form, -ose suffix².

Etymology: < bi- comb. form + -ose suffix²; in sense 1 after French biose (B. Rayman 1887, in Bull. de la Soc. Chim. 47 676); in sense 2 after German Biose ( E. O. von Lippmann Chem. der Zuckerarten (1895) (ed. 2) i. 1).C. Scheibler (1885, in Berichte der Deutsch. Chem. Ges. 18 647) earlier proposed the use of the suffix -biose for disaccharides; compare:1886 Jrnl. Amer. Chem. Soc. 8 118 The recent suggestion of Scheibler..in regard to the terminations -ose and -biose in the nomenclature of sugars of the glucose and saccharose classes respectively, is a step in the direction of the above suggestion.

1. = disaccharide n.

1887 Jrnl. Amer. Chem. Soc. 9 111 Products of condensation of groups 2 and 3, bioses and trioses.

1948 R. J. McIlroy Chem. Polysaccharides iii. 22 Doubts..have been expressed of the validity of cellobiose and maltose as units of cellulose and starch respectively. It has been suggested that these bioses are merely reversion products produced by chemical action upon the ultimate glucose units.

1982 Carbohydrate Res. 107 263 A comparison is also made between ¹³C-n.m.r. characteristics of the bioses and those of structurally related d-glucans.

2. A sugar with only two carbon atoms in its molecule. Cf. diose n.The only such compound known is glycolaldehyde or 2-hydroxyethanal (C₂H₄O₂).
