A method is described for the chemical synthesis of stigmasta-5,24-dien-3β-ol-[26-14C] and (24S)-24-ethylcholesta-5,25-dien-3β-ol-[26-14C] (clerosterol). 28-Isofucosterol-[7-3H2] fed to developing barley seedlings (Hordeum vulgare) was incorporated

A series of oxygenated carotenoids has been isolated from tomatoes. Two of these compounds have been identified, by comparison of their chromatographic and spectroscopic properties with those of semisynthetic samples, as epoxides of lycopene (1,2-epo

[4α-3H]Cholesterol was prepared in three steps from 4-oxo-cholest-5-en-3β-yl acetate, which was conveniently prepared from cholesterol. Introduction of the 4α 3H label utilised NaB3 H4 as the source of tritium. Details of this synthesis and also t

Excised barley embryos cultured on a nutrient medium containing methionine-[CD 3 ] incorporated deuterium into the newly biosynthesized sterols. Two deuterium atoms were present in 24-methylenecycloartanol, 24-methylenelophenol and campesterol and a

1. The fates of the alpha-, 4 alpha- and 4 beta-hydrogen atoms of cholesterol during formation of the A/B cis ring junction of ecdysteroids was investigated by administration of [4-14C, 3 alpha-3H], [4-14C, 4 alpha-3H]- and [4-14C, 4 beta-3H]choleste
