Abstract

Investigation of the ascorbic acid (AsA) status of the blue crab, Callinectes sapidus, and the grass shrimp, Palaemonetes pugio. indicated that both organisms possess significant quantities of AsA and ascorbate 2-sulfate (AAS), but have only limited synthetic abilities. High concentrations of AsA were found in crab hepatopancreas and shrimp cephalothorax, whereas gill and muscle tissue had low quantities of AsA. AsA concentrations were influenced by molt-cycle, seasonal, dietary, and ontogenetic variations. Both organisms were able to utilize AAS reserves to fulfill AsA requirements during dietary or pollutant stress.
