In 1929 he isolated oestrone in pure, crystalline form, almost at the same time that.    From Wordnik.com.  [Adolf Butenandt - Biography] Reference

Butenandt named this substance folliculine, a designation which was later changed to oestrone.    From Wordnik.com.  [Nobel Prize in Chemistry 1939 - Presentation Speech] Reference

It differs from oestrone only in the additional content of 1 methyl group and 5 hydrogen atoms.    From Wordnik.com.  [Nobel Prize in Chemistry 1939 - Presentation Speech] Reference

Butenandt confirmed Marrian's discovery and explained the relationship between the new substance and oestrone.    From Wordnik.com.  [Nobel Prize in Chemistry 1939 - Presentation Speech] Reference

In 1929-1930 he succeeded in isolating oestrone, a feat independently accomplished at about the same time by Butenandt in.    From Wordnik.com.  [Edward A. Doisy - Biography] Reference

In the process of purification it proved that the male hormone behaved in many respects like oestrone; when he realized this, it made Butenandt's work considerably easier.    From Wordnik.com.  [Nobel Prize in Chemistry 1939 - Presentation Speech] Reference

In 1932, Butenandt was able, from observations made in spectral analysis, and especially on the basis of the then established correct formula of cholesterol to draw up the formulae of the chemical structure of oestrone and oestriol.    From Wordnik.com.  [Nobel Prize in Chemistry 1939 - Presentation Speech] Reference

The steroid sulfatase pathway gives rise to oestrone and dehydroepiandrosterone (DHEA) that in turn produce oestradiol and androstenediol.    From Wordnik.com. Reference

They take a blood sample from the mare and send it to a veterinary diagnostic laboratory for measurement of the oestrone sulphate concentrations.    From Wordnik.com.  [Horsetalk.co.nz Headlines] Reference

The two hormones most commonly measured are pregnant mare serum gonadotrophin (PMSG), which is now often called equine chorionic gonadotrophin (eCG), and oestrone sulphate.    From Wordnik.com.  [Horsetalk.co.nz Headlines] Reference

By day 100 of pregnancy, the mare's blood concentrations of oestrone sulphate are consistently at least twice, and generally more than five times, the highest concentrations found in non-pregnant mares.    From Wordnik.com.  [Horsetalk.co.nz Headlines] Reference

The two chemical hormones commonly measured to provide information on the pregnancy status of miniature mares are pregnant mare serum gonadotrophin (PMSG), which is frequently now called chorionic gonadotrophin (eCG), and oestrone sulphate (see main story for more information).    From Wordnik.com.  [Horsetalk.co.nz Headlines] Reference

"Measuring blood oestrone sulphate concentrations earlier than 100 days post-breeding is not recommended, as a false negative diagnosis could arise if the pregnant mare still has blood oestrone sulphate concentrations in the upper part of the normal non-pregnant range.    From Wordnik.com.  [Horsetalk.co.nz Headlines] Reference
