Threonine requirement of parenterally fed postsurgical human neonates.
BACKGROUND The threonine requirement of human neonates who receive parenteral nutrition (PN) has not been determined experimentally. OBJECTIVE The objective was to determine the parenteral threonine requirement for human neonates by using the minimally invasive indicator amino acid oxidation technique with L-[1-(13)C]phenylalanine as the indicator amino acid. DESIGN Nine postsurgical neonat...
متن کاملPlasma amino acid concentrations in parenterally fed preterm infants.
One hundred and nine sick preterm infants were studied, and the data obtained show that hyperphenylalaninaemia is an extremely rare occurrence as long as an adequate source of energy is provided. High concentrations of the other aromatic amino acid (tyrosine) on the other hand, were often encountered and seem to be due to immaturity of an isolated hepatic enzyme as there was no correlation betw...
متن کاملExperimental injury and sulfur amino acid metabolism.
It has been reported that methionine and cystine are capable of accelerating the healing rate of wounds in injured rats to the same extent when present in the diet in equivalent amounts (1). This response was elicited in both the presence and the absence of dietary protein (2). Lysine, tryptophan, and valine do not appear to alter the healing process to a significant degree (3). Because methion...
متن کاملIntestinal amino acid metabolism in neonates.
The portal-drained viscera (stomach, intestine, pancreas and spleen) have a much higher rate of both energy expenditure and protein synthesis than can be estimated on the basis of their weight. A high utilization rate of dietary nutrients by the portal-drained viscera might result in a low systemic availability which determines whole-body growth. From studies in our multiple catheterized piglet...
متن کاملEstimation of the total sulfur amino acid requirement and the effect of betaine in diets deficient in total sulfur amino acids for the weanling pig.
Four experiments were conducted to determine whether betaine (BET) could replace dietary methionine (MET) in diets for weanling pigs. Pigs in each experiment were allotted to treatments on the basis of weight in a randomized complete block design. Each treatment was replicated four (Exp. 4), five (Exp. 1 and 2), or six (Exp. 3) times with five or six pigs per replicate. In Exp. 1, pigs were fed...
