The occurrence of inositol and of p-amino benzoic acid in sweat.

The occurrence of many of the water-soluble vitamins in sweat has been reported in recent years. Sargent, Robinson, and Johnson (1) have reviewed the literature on the occurrence of ascorbic acid, dehydroascorbic acid, thiamine, riboflavin, pantothenic acid, and nicotinic acid in sweat. We have demonstrated the presence of pyridoxine and its metabolites (2), choline (3), N1-methylnicotinamide (4), “folic acid” (5), and biotin’ in sweat. In this paper we wish to report the occurrence of inositol and of p-aminobenzoic acid in sweat and the effect of a “hot moist” environment on the excretion of inositol.
