Vitamin A (Retinol) Molecular Structure - 3D Ball-and-Stick Model #3313869 (License: Personal Use)

This high-resolution 3D model illustrates retinol, the alcohol form of vitamin A, featuring a six-membered β-ionone ring connected to a polyunsaturated isoprenoid side chain ending in a hydroxyl group (-OH). The molecule contains 20 carbon atoms, 30 hydrogen atoms, and one oxygen atom, critical for its role in vision, immune function, and cellular differentiation. The red sphere marks the reactive hydroxyl group essential for biological activity.

Used in educational, medical, and nutritional science contexts-such as biochemistry textbooks, health websites, or supplement product pages-to visually explain vitamin A’s chemical structure and functional groups. Matches user intent for learning molecular biology, nutrition science, or researching fat-soluble vitamins.
