F nce kino and okumura 1987 estimated nitrogen balance in 1421 day old chickens as 029 gday. Using amino acid tracers we can measure protein synthesis breakdown oxidation and net balance. 1981 etude de la synthse protrique in vivo dans le muscle de la truite arc en ciel salmo gairdneri r. Again do not mistake it for muscle protein synthesis which is protein synthesis specifically of muscle protein. These studies were undertaken to determine to what extent constant infusion measurements and plasma sampling could provide sensible answers for rates of whole body protein turnover and also which amino acid would be the most representative probe of whole body protein turnover. Furthermore measurement of the rate of whole body protein synthesis from the specific activity of tissue amino acids at the end of the infusion may not provide a more reliable estima.

Whole body protein synthesis and breakdown were determined using repeated oral administration of 15 n glycine for 6072 h and 15 n enrichment in urinary urea was measured. Rates of whole body protein synthesis and breakdown expressed as g proteinkg body weightday were significantly p less than 005 and positiviely correlated with per cent body surface area total burn per cent third degree burn and per cent open wound. The aim of this study was to evaluate whole body protein synthesis and plasma and muscle amino acid concentrations in response to graded levels of lysine intake in yearling horses. Whole body net protein synthesis can be estimated by nitrogen balance. Note that protein synthesis refers to protein synthesis of any protein in the body whole body protein synthesis. The mean postabsorptive total body protein synthesis rate in three normal controls was 25 g proteinkgday.

Plateau enrichment of 15n ammonia following 24 hour continuous intravenous infusion of 15n glycine was used to measure total body protein turnover and synthesis in normal volunteers and malnourished patients with and without cancer. Six thoroughbred colts 358 5 kg were fed each of six treatment lysine intakes ranging from 76 to 136 mgkg body weightday. If negative whole body protein net synthesis accretion is whole body protein net degradation. Influence of environmental tem perature in press. Fauconneau b arnal m. Whole body protein synthesis rates were estimated in 70 g rats with.

Where whole body protein losses includes in proteins in eggs or molted feathers. In vivo protein synthesis in different tissues and the whole body of rainbow trout salmo gaidneri r. Measurement of whole body protein turnover protein synthesis breakdown and net balance enables quantification of the response to a variety of circumstances including the response to meal feeding. Underestimate whole body protein turnover to a variable extent with different amino acids 12 36.
