Glucose and Proline Metabolism in Nautilus

Abstract

The rates of incorporation of [U-14C]proline and [U-14C]glucose into CO2 and glycogen were assessed in Nautilus pompilius under both in vitro and in vivo conditions. Both substrates exhibited tissue-specific rates of metabolism. However, overall higher rates of incorporation into CO2 and glycogen were observed with glucose, both with tissue slices and in the intact, catheterized organism.
