Extract

It has been observed that the pH in the different parts of the alimentary canal of Corophium is nearer neutrality; while the medium in the ventral hepatopancreatic caeca is more acidic, being in the neighbourhood of 6.2.

Investigations on the qualitative estimation of enzymes indicate that none of the enzymes are secreted by the gut proper. However, the ventral caeca only secrete many of the carbohydrate splitting enzymes; proteases and lipase are also secreted by the caecal cells of Corophium

It has also been estimated that the optimum pH for the activity of the caecal amylase lies in the neighbourhood of 5.8.
