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.10 p.application/pdfeng(c) The Nutrition Society, 1993FetgeIntestinsNitrogen en l'organismeProteïnesLiverIntestinesNitrogen in the bodyProteinsIntestinal and hepatic nitrogen balance in the rat after the administration of an oral protein loadinfo:eu-repo/semantics/article79720info:eu-repo/semantics/openAccess
