What is Isobemisiose?

Plain description, key identifiers and synonyms

Isobemisiose is a glucotriose that is alpha-D-glucopyranosyl-(16)-alpha-D-glucopyranoside in which the anomeric hydroxy group has been converted into the corresponding alpha-D-glucopyranoside. An unusual trisaccharide abundant in the silverleaf whitefly, Bemisia argentifolii. It is a glucotriose and a glycosyl glycoside derivative.
