描述

The Hydrolysis of Steroid Conjugates,From the very earliest studies in the twenties, when steroid hormone research was in its infancy, the hydrolysis of conjugates has been a major interest of steroid investigators. Except for a tiny fraction excreted as free compounds, steroid hormones and their metabolites are excreted as conjugates.

Here, however, attention will be restricted to those enzymes directly related to the metabolism of steroid conjugates and, furthermore, of only those steroid conjugates whose metabolism ha

It was not until 1936, however, that the pioneer efforts of Cohen and Marrian [1] and Venning and Browne [2]

However, it seems to us that there are other, more trenchant, reasons for this exceptional treatment. Although scores of steroid sulfates have been isolated or detected in body tissues and fluids, only those of t

In addition, an N-acetylglucosamine conjugate of 17α-estradiol has been isolated from the urine of rabbits [7], and preliminary evidence ha

These investigators noted that acidification of male urine to pH 4.0–4.5 and continuous extraction with chloroform led to an enhancement of the biological activity of the extract. This observation was confirmed by Kabak in 1931 [2] and by Adle
