Summary

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.

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

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。
