Antibody Structure Diagram - Visual Guide to Immune System Proteins #3894574 (License: Personal Use)

This illustration depicts multiple antibody (immunoglobulin) molecules in a stylized, schematic form. Each antibody features a classic Y-shape with two identical antigen-binding fragments (Fab) at the tips-shown in orange-and a constant fragment (Fc) region in blue. The design emphasizes structural symmetry and binding specificity, commonly used to explain adaptive immunity.

Used in immunology education, medical websites, textbooks, and scientific presentations to illustrate how antibodies recognize and bind antigens; matches user intent for learning basic immune mechanisms or visualizing molecular biology concepts.
