Abstract:
Three new pregnane steroids, 2beta,3beta,5beta-trihydroxy-pregn-20-en-6-one (1), 3beta-hydroxy-5alpha-pregn-7,20-dien-6-one (2), and 3beta-acetoxy-5alpha-pregn-7,20-dien-6-one (3) were isolated from the twigs and leaves of Turraea pubescens, and were structurally elucidated on the basis of spectroscopic data and chemical method.

Gonadal and Placental Hormones
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair growth — and...
Hormones of the Adrenal Glands
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and corticosterone...
