About the Protein Structure Ribbon black filled icon
A ribbon folds back and forth in a tight zigzag that runs diagonally across a circular badge, echoing the pleated structure of a protein molecule. It stands for protein content, muscle nutrition and biochemistry, fitting supplement packaging, gym and diet apps, nutrition labels, lab and biology slides, and health article headers.
Each fold is drawn as a narrow parallelogram of equal width, so the chain reads as one continuous band rather than loose strokes. It sits well with DNA, dumbbell and nutrition icons. Keep the badge ring for contrast when placing it on busy packaging.
This is the solid black filled version of the protein structure ribbon icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
