caption: The image shows the chemical structure of a peptide molecule on a white background. The molecule is composed of a series of hexagonal structures, each with its own unique shape and color. The colors range from light blue to dark blue, with the lightest blue being the most prominent. The structures are arranged in a symmetrical pattern, with each molecule having its own distinct shape and size. The background is a bright white, providing a stark contrast to the dark blue of the molecule.
