About the Protein Alpha Helix black filled icon
A ribbon twists into four even coils, drawn as a continuous helix seen from the side — the way an alpha helix or collagen strand is pictured in biology diagrams. It communicates protein, amino acids and molecular structure rather than a food item. Use it on supplement labels, collagen skincare claims, nutrition apps, biotech pitch decks and lab report headers.
Each turn repeats at the same width and pitch, so the coil scans as a regular spring, while the open ends at left and right suggest a longer chain continuing past the frame. Pair it with DNA, molecule and lab flask icons, and give it wide horizontal space.
This is the solid black filled version of the protein alpha helix 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.
