Quantitative estimation of glycogen phosphorylase in Neokrimia singhia (cestode) parasitic in Perdicula asiatica

Abstract

Glycogen phosphorylase presence indicated that the parasite utilized glucose through glycolsis for energy turn over in preference to glycogen. Glycogen was important substrate in the initial phase of HMP pathway. The glucose residues in glycogen were mobilized by the enzyme glycogen phosphorylase. The amount of ‘a’ and ‘ab’ glycogen phosphorylase was estimated biochemically in Neo krimia singhia. The phosphorylase content of mature proglottid was higher followed by gravid and immature. A similar gradient as that of glycogen was found along the strobila.
