Abstract
The distribution of carbohydrates, lipids and proteins including enzymes in the alimentary canal of Chalcides levitani are described. Both neutral and acidic mucosubstances are identified in the epithelial cells. Neutral mucosubstances are most evident in the stomach and acid mucosubstances are more abundant in the intestine. Sulfomucins as well as sialomucins show different patterns of distribution. The present investigation shows that the principal digestive enzymes: acid phosphatase, alkaline phosphatase, non·speciflc ester. ases, arninopeptidases, endopeptidases, trypsin-like enzyme, beta-galactosidase and beta-glucuronidase are revealed histochemically. Lipases and alphaglucosidase do not appear to be produced anywhere in the alimentary tract epithelium.
