Homeostatic regulation of plasma amino acid concentrations.
One major goal of nutrition is to maximize the rate of muscle protein gain via provision of amino acids (AAs) through blood plasma. Comparing the plasma AA concentrations with the growth performance data can help to elucidate the metabolic mechanisms regulating plasma AA homeostasis, nutrient utilization, and intracellular protein turnover. Knowledge about the homeostatic regulation of plasma A...
متن کاملNormal Range of Total Plasma Homocysteine Concentrations in Southern Iran
The distribution of total plasma homocysteine concentrations in relation to the sex and age is described, in a population of Shiraz, South West of Iran and compared to those reported in other populations. Two hundred and one healthy males and 201 healthy females aged >15 y were randomly selected. Total Plasma homocysteine concentrations were measured using high performance liquid chromatograp...
متن کاملrapid and simple determination of plasma amino acid ratio
in recent years considerable interest has been focused on the plasma amino acid patterns as a possible index of protein malnutrition, in children. thus a change in the ratio of non-essential to essential amino acids is considered to be significant in the development of protein malnutrition. the present paper reports a simplified and rapid chromatographic procedure for the determination of this ...
متن کاملMeasuring total plasma amino acid concentrations as a test of exocrine pancreatic function.
Endogenous and exogenous stimulation of the pancreas was studied to determine whether changes in protein output could be linked to decreased total plasma amino acid concentrations. In fasted rats, diversion of pancreatic juice resulted in a transient increase in protein output and a linked fall in total plasma amino acid. In fed animals, however, diversion of juice did not result in any change ...
متن کاملPlasma amino acid concentrations in healthy elderly men and women.
Postabsorptive plasma concentrations of the large neutral amino acids (LNAAs) were measured in 74 elderly (age 71 +/- 8 y) and 138 young (age 26 +/- 5 y) healthy subjects. Plasma concentrations of valine, leucine, and isoleucine were significantly lower in young females than in young males. This gender-related difference was not observed among elderly subjects because aging was associated with ...
