Urinary excretion of 5-L-oxoproline (pyroglutamic acid) is increased in normal adults consuming vegetarian or low protein diets

A method for measuring 5-L-oxoproline in urine, which involves isolation by short-column
chromatography, acid hydrolysis to glutamic acid and enzymic assay of glutamic acid, was
used to measure the rate of excretion in normal adults, aged 20 to 45 y. There was no
difference in the daily excretion between omnivorous males (217 µmol/d) and females (195
µmol/d). In vegetarian males, urinary 5-L-oxoproline (404 µmol/d) was significantly greater
than in vegetarian females (267 µmol/d, P= 0.013). Compared with omnivorous males or …
