Free amino acid excretion in tetraplegic patients

Amino acid excretion in primary hyperuricaemia.

Oxoproline kinetics and oxoproline urinary excretion during glycine- or sulfur amino acid-free diets in humans.

L-5-oxoproline (L-5-OP) is an intermediate in glutathione synthesis, possibly limited by cysteine availability. Urinary 5-OP excretion has been proposed as a measure of glycine availability. We investigated whether 5 days of dietary sulfur amino acid (SAA-free) or glycine (Gly-free) restriction affects plasma kinetics of 5-OP and urinary excretion of L- and D-5-OP in 6 healthy men. On day 6, L-...

Vitamin D and urinary amino acid excretion in the rabbit.

There is ample evidence that vitamin D deficiency rickets in man is associated with hyperaminoaciduria (1). Further studies (2) on renal clearance have de monstrated that elevated urinary amino acid excretion results from diminished reabsorption of it by the renal tubular cells. Many attempts (3, 4), however, failed to find aminoaciduria in experimental rachitic animals until GROSE and SCRIBER ...

Urinary amino acid excretion in subjects with leukaemia.

Urinary amino acid chromatograms were studied from 33 patients with various types of leukaemia and 71 control subjects. Marked variations were found in the excretion of methionine, threonine, valine, leucine, tyrosine, histidine, and aspartic acid.

Free amino acid content in infant formulas

Purpose – Infant formula is the sole nutrition and food source for many infants. Information on the free amino acid (FAA) content of formulas, particularly those that are protein hydrolysate based, is limited, despite emerging evidence for the role of FAAs in regulating eating behaviour. The purpose of this paper is to measure levels of essential, semi-essential, and nonessential FAAs in commer...
