Steroids and other lipids of pregnant goat's urine

Shinfleld, to study the steroids of pregnant goat's urine with particular attention to oestrogens and pregnanediol.It was intended to provide a basis for studies on the metabolism of administered steroids and on pathological conditions.It has also served as a preliminary to similar work on pregnant cow's urine.Preliminary accounts of this work have been given already (Wright & Klyne, 1955; 'Klyne & Wright, 1956a).Previous work Little work on the constituents of goat's urine has been described in the literature.Anderson (1916) studied the volatile constituents and isolated p- cresol and a non-phenolic ketone, C1oH160, which was identical with a substance from cow's urine.* Impure: three other 17-oxo steroids were partially characterized.henolic g.)
