In vivo control of hemolymph alpha glucosidase kinetics by glycemic components according to the developmental stages of worker bees apis mellifica mellifica



In vivo control of hemolymph alpha glucosidase kinetics by glycemic components according to the developmental stages of worker bees apis mellifica mellifica



Comparative Biochemistry & Physiology B 66(3): 335-342



The main following correlations were found between the .alpha.-glucosidase kinetics and the glycemia as determined in worker bee hemolymph. The maximum velocity (Vm) is positively correlated with the trehalosemia (T) within each stage, but negatively from one stage to another. The affinity constant (K) is positively correlated with the glucosemia (G) within each stage, and negatively again over the entire development range. The Hill coefficient (nH) is only negatively correlated with the glucosemia within each stage. These enzymic mechanisms allow an auto-control of the (T)/(G) ratio, as a complement to other (hormonal) ways of glycemic regulation.
