Distribution of Choline Acetylase in Insect Conductive Tissue

IT has been clearly shown that insects contain acetylcholine, cholinesterase and choline acetylase, and the work of Smallman1–3 has done much to evaluate these. Since then, a more specific study of the substrate and enzymes in the conductive tissue of the American cockroach, Periplaneta americana L., has shown that acetylcholine occurs most abundantly in… CONTINUE READING
