title: Hepatic protein and amino-acid metabolism in poultry.
abstract: Two subjects are discussed: first, the regulation of hepatic protein synthesis; and second, the intermediary metabolism of methionine, particularly with respect to the role of 2-hydroxy-4-(methylthio)-butanoic acid (HMB, Alimet). In the first section, the regulation of albumin synthesis is reviewed in terms of molecular events associated with the changes in albumin synthesis during fasting and refeeding. The effect of infection or of inflammatory stress on both albumin and total protein synthesis in the liver is also discussed. In the second part, research results are presented which indicate that HMB is a naturally occurring compound in methionine intermediary metabolism. The HMB synthesis by chick liver enzymes is demonstrated, and its role in normal avian methionine metabolism is discussed.
