This study examined plasma proline concentration flux, oxidation, and endogenous
biosynthesis in five healthy young men given three isocaloric, isonitrogenous diets for 1 wk …

The effects of removing proline from the diet on plasma leucine and proline kinetics were
investigated. After a 1-wk control period, during which young adult men received a diet …

A quantitative exploration of the regulation of plasma proline concentration, proline
oxidation, and proline endogenous biosynthesis was undertaken utilizing a 360-minute …

Postabsorptive proline flux, oxidation, and endogenous biosynthesis were determined in five
severely burned intensive-care-unit patients (x̄age 27 y) and in six healthy, young-adult …

Introduction Proline is widely found in all types of mammalian tissue, and accounts for about
20% of the amino acids that constitute collagen (A dams 1970). Proline is nutritionally …

Dietary reduction of a nonessential amino acid, proline, might be expected to be difficult
since imino acids may be continuously synthesized from endogenous precursors. In this …

The effect of two dietary concentrations of proline (10.3 and 15.8 g/kg) on proline-
metabolizing enzymes [pyrroline-5-carboxylate (P5C) reductase and proline oxidase] …

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 …

Traditionally, proline is categorized as one of the nonessential amino acids in mammals,
however, proline is indispensable in the neonatal small intestine. In addition, proline has …

Arginine and proline derive from the metabolism of Δ1-pyrolline-5-carboxylate, a product of
intestinal glutamic acid metabolism. We studied the extent of glutamate, arginine, and …
