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.

Attention

moisture sensitive

The saccharide profiles of 5 different botanical species in 86 Italian honey samples were investigated by ¹H and ¹H-¹³C NMR spectroscopy. Nineteen saccharides were identified in the aqueous extracts, namely, fructose, glucose, gentiobiose, isomaltose, kojibiose, maltose, maltulose, melibiose, nigerose, palatinose

The purification and characterisation of the alpha-glucosidase from the marine mollusc Aplysia fasciata are reported. Overall substrate specificity of the pure enzyme for both hydrolytic and transglycosylation reactions was studied. Remarkable characteristics of this enzyme are indicated by the results

An isomelezitose synthase was redesigned out of the sucrose isomerase from Protaminobacter rubrum for the synthesis of isomelezitose (6-O(F)-glucosylsucrose), a potential nutraceutical. The variants F297A, F297P, R333K, F321A_F319A and E428D catalyze the formation of isomelezitose in up to 70 %
