Heptoses experiments

In the same way, condensation experiments have been performed with v-glycero-D-gulo-heptose and ethyl acetoacetate, and a crystalline product has been isolated this also gave the aldehyde V16 when oxidized with periodate. Hence, in this case also, the reaction is analogous to that with the hexoses, although the yield is lower. 

Roe and Hudson demonstrated that D-mannoheptulose is physiologically available to the rabbit, which has a high tolerance for this heptose. This prompted Hiatt and coworkers to study the capacity of the corresponding polyol, D-volemitol, which occurs in mushrooms and Primula species, as a precursor of glycogen in the liver of the white rat. Through a series of feeding experiments, Hiatt et al. concluded that...
