title: [Effect of nicotinic acid on chicken liver protein kinase activity and cAMP content].
abstract: The biosynthesis of fatty acids in the chicken liver was stimulated by feeding up chickens with high-carbon products. After fasting the cAMP content and protein kinase activity in chicken fall considerably as compared to the control. After administration of nicotinic acid to chicken under experiment the content of cAMP and the protein kinase activity in the liver tissue rise to the highest extent, returning to initial values by the end of the day. The maximal increase in the cAMP content and protein kinase activity coincides in time with the maximum of the acetyl-CoA-carboxylase activity decrease. An assumption is advanced that biosynthesis of fatty acids in the liver tissue of chickens is regulated by a change in the degree of acetyl-CoA-carboxylase phosphorylation with the participation of adenylate cyclase system.
