A glucocerebroside was isolated from the n-alkane-assimilating yeast Candida deformans MIL 4041 and named "Deformin". The cerebroside contained only a single sugar, glucose, attached to ceramide in a beta- configuration, and only a single fatty acid, 2-hydroxypalmitic acid. The long-chain base was identified as (5E, 9Z)-C-19-sphinga-5,9-diene. Therefore, the structure of the cerebroside was determined to be (5E, 9Z)-N-2’-hydroxypalmitoyl-1-O-beta-glucopyranosyl-2-amino-5,9-nonadecadiene-1,3-diol. Deformin showed the fruiting-inducing activity of fungi.
