A schematic diagram showing the chemicals, enzymes, and locations of the human steroidogenesis pathways.

Summary

edit
Description
English: *Enzymes, their cellular location, substrates and products in human steroidogenesis.

Shown also is the major classes of steroid hormones: progestagens, mineralocorticoids, glucocorticoids, androgens and estrogens. However, they partly overlap, e.g. mineralocorticoids and glucocorticoids.

  • White circles indicate changes in molecular structure compared with precursors. For more information on interpretation of molecular structures, see structural formula.
  • Arrows are shown as unidirectional to indicate the usual net directions, but technically all biochemical reactions are considered bidirectional.

HSD: Hydroxysteroid dehydrogenase

There is no appreciable conversion of corticosterone to cortisol in the adrenal cortex as 21-OH steroids are poor substrates for 17-alpha hydroxylase.

日本語: この図はヒトのステロイドホルモン生成における酵素と酵素が存在する細胞器官、基質ならびに生成物の全体図である。またこの図は(コレステロールから)プロゲステロン、鉱質コルチコイド、糖質コルチコイド、そしてアンドロゲンおよびエストロゲンに至る主要なステロイドを記述している。

図に示すとおりそれぞれ(生合成の過程で)オーバーラップするものである。 図中、白い円で囲んだところは基質と比較した分子構造の変化した箇所を示す。

なお、HSD は、ヒドロキシステロイドデヒドロゲナーゼを表す。
