Co-ordinated synthesis of gentiobiitol and sorbitol, evidence of sorbitol glycosylation in transgenic sugarcane

Metabolite profiling of sugarcane (a Saccharum spp. interspecific hybrid) that was engineered to accumulate sorbitol revealed that the sugar alcohol 6-O-β-d-glucopyranosyl-d-glucitol (gentiobiitol) was a major by-product.
