This part of the antibody binds to epitopes. Image description: This is a simplified depiction of the structure of an antibody. There are 2 dark blue segmented lines that form the shape of a Y. There are 2 shorter green segmented lines that are parallel to the top part of each side of the blue Y. Arrow A points to the top of the blue and green structures at the top of the Y. B points to the bottom of the green segmented line. C points to the top of the stem part of the Y of the blue segmented line. D points to the bottom of the stem part of the Y of the blue segmented line.
