UREA, AMINO ACID AND AMMONIA IN HUMAN SWEAT

Abstract

The contents of urea, amino acid and ammonia of sweat were measured in association with the rate of secretion and the specific function of the duct. The urea content of sweat was always above serum level, while the amino acid content was below serum level and ammonia of sweat was much higher. It was surmised that the concentrating mechanism of urea existed in the sweat gland duct and it was also supposed that there is a limited reabsorbent ability of amino acid in sweat.
