Abstract

The exceptionally high lipid levels in the muscle and liver of Geotria australis, at the completion of the marine trophic phase, are both accompanied by a very high activity of acetyl-CoA carboxylase (ACC). ACC activity declines markedly during the subsequent protracted, nontrophic spawning run. The above and other data suggest that, in lampreys, the muscle tissue, as well as the liver, is lipogenic. Carnitine palmitoyl transferase I of lamprey muscle is extremely sensitive to malonyl-CoA, a feature which would enable fatty acid oxidation to be inhibited during any period of lipogenesis in this tissue.
