Abstract
As early as 1905, Wendt1 pointed out the importance of determining urinary sulphur in studies of protein metabolism. The studies of Cathcart and Green2, Wilson3–5 and Basu et al.6 have demonstrated that most of the sulphur excreted as urinary sulphate in man results from the oxidation of the sulphur amino-acids absorbed in the intestine and those from tissue breakdown. It would be expected, therefore, that urinary sulphate would reflect, under certain conditions, the amount of dietary sulphur amino-acids being absorbed, thus their ‘biological availability’ from various foods. The present experiments were undertaken to investigate the relation between the sulphur amino-acids in the diet and the excretion of urinary inorganic sulphate in man.
