About the Protein black outline icon
An oval outline frames a ribbon that folds back and forth like a coiled protein helix, the shape used in biology diagrams for an amino acid chain. It stands for nutrition, muscle building and molecular science at once. Use it on supplement labels, macro trackers, gym meal plans, food packaging panels and biotech slide decks.
The helix is drawn with even loops and a consistent stroke weight so it stays legible inside the surrounding ellipse. It works in a nutrient set beside carbohydrate, fat, vitamin and calorie icons. Because the loops sit close together, keep it at 40 px or larger.
This is the black outline version of the protein icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
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.
