DISTRIBUTION OF PHOSPHORYLASE IN SOME FISH AND SHELL FISH.

Abstract

Phosphorylase content m the muscle of some fish and
shell fish were estimated. Jew fish (Johnius duss~uneri) and 'sea
naran' (Penaeus indicus) recorded the highest enzyme content
among the fish and shell fish studied. As phosphorylase is the
key enzyme in glycogenolysis, which is the energy source of
fish for muscular activity, the possible role of phosphorylase
content as an index of muscular capacity and post-mortem
autolysis is discussed.
