Application

Erlose, a triose sugar (trisaccharide), is used in studies on dietary preference and utilization of triose sugars from aphid honeydew by various insects, such as honey bees and ants. Erlose may be used as a reference compound in assays that analyze the sugars of foods such as royal jelly and honey.

Caution

moisture sensitive

Little is known about the structure and function of oligosaccharides in cyanobacteria. In this study, a new class of saccharides from Nostoc was identified by MS and NMR techniques, consisting of alpha-D-glucopyranosyl-(1-->2)-[alpha-D-glucopyranosyl-(1-->2)]n-beta-D-fructofuranosides ranging from the trisaccharide (n = 1) to

Like honey bees (Apis mellifera), non-Apis bees could exploit honeydew as a carbohydrate source. In addition to providing carbohydrates, this may expose them to potentially harmful plant products secreted in honeydew. However, knowledge on honeydew feeding by solitary bees is

Resting-cell suspensions of oral microorganisms grown in sucrose were studied for the production of acid from glucosylsucrose and maltosylsucrose. Most oral microorganisms fermented these sugars to only a limited extent. Streptococcus salivarius, however, metabolized glucosylsucrose as well as sucrose. We
