Abstract: | 1. Significant differences were detected by 31P NMR spectroscopic techniques in the intrinsic rate of ATP hydrolysis by crystalline lenses from adult Macaca mulatta, Saimiri sciureus, Felis catus, Sus, Canis familiaris, Cavia rodentia and Oryctalagis cuniculus during exogenous glucose deprivation. 2. These differences were not attributable to differences in endogenous glycogen stores, and appear instead to emanate from comparative species differences in lenticular enzyme activities. |
