About the Hormones Steroid Molecule black filled icon
Four hexagonal carbon rings are fused into a stepped steroid skeleton, with three short bonds ending in small open circles that mark attached hydroxyl or functional groups. It depicts a hormone molecule such as estrogen or testosterone, communicating endocrine chemistry and biological signalling. Use it in medical and lab software, endocrinology clinic pages, biology and chemistry teaching slides, supplement packaging, and health research reports.
The ring cluster runs on a diagonal so the molecule fills a square frame evenly, with the bond circles breaking the outline at three corners for balance. It pairs with DNA helix, test tube, gland and blood drop icons. Keep the stroke thin and the size at 32 px or more so the ring joins stay distinct.
This is the solid black filled version of the hormones steroid molecule icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
