Intestinal and hepatic nitrogen balance in the rat after the administration of an oral protein load Fernández López, José Antonio Casado, Javier (Casado Merediz) Rafecas Jorba, Immaculada Esteve Ràfols, Montserrat Argilés Huguet, Josep Ma. Remesar Betlloch, Xavier Alemany, Marià, 1946- Fetge Intestins Nitrogen en l'organisme Proteïnes Liver Intestines Nitrogen in the body Proteins The fate of a small oral dose of protein given to overnight-starved rats was studied. After 3 h, 62 per cent of the protein amino acids had been absorbed. Most of the absorbed N went into the bloodstream through the portal in the form of amino acids, but urea and ammonia were also present. About one-quarter of all absorbed N was carried as lymph amino acids. The liver was able to take all portal free ammonia and a large proportion of portal amino acids, releasing urea. The hepatic N balance was negative, indicating active proteolysis and net loss of liver protein. 2012-02-17T09:05:27Z 2012-02-17T09:05:27Z 1993 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Reproducció del document publicat a: http://dx.doi.org/10.1079/BJN19930074 British Journal of Nutrition, 1993, vol. 69, p. 733-742 http://dx.doi.org/10.1079/BJN19930074 (c) The Nutrition Society, 1993 info:eu-repo/semantics/openAccess Cambridge University Press, 1993 Articles publicats en revistes (Nutrició, Ciències de l'Alimentació i Gastronomia)
