BACKGROUND Although there are several published estimates of the endogenous amino acid composition of ileal digesta in humans, to our knowledge, there are no systematic studies of ileal digesta endogenous proteins. OBJECTIVES We determined the nature and composition of endogenous nitrogen-containing substances lost from the upper digestive tract of humans. DESIGN Digesta were collected from...
A study was undertaken of patients on a regimen of total parenteral nutrition comparing the nitrogen balance, energy substrates, blood amino acids, immunoreactive insulin, and immunoreactive glucagon levels during the sequential infusion of nonprotein calories as either glucose alone (glucose system) or 83% as Intralipid (Pharmacia Fine Chemicals, Montreal, Canada) and 17% glucose (lipid system...
A simple procedure for the estimation of plasmaamino nitrogen basedon the reaction of amino groupswith 2,4-dinitrofluorobenzene (DNFB) and subsequentmeasurement of the dinitrophenyl (DNP) amino derivatives at 420 m is presented. Elevated concentrations of bilirubin, hemoglobin, and the major nonprotein and nonamino acid nitrogen components of plasma do not seriously interfere. The proposed proc...
