Cysteine Amino Acid Molecular Structure - 3D Visualization #25784 (License: Personal Use)

This high-resolution 3D ball-and-stick model depicts the cysteine amino acid, featuring a central alpha carbon bonded to an amino group (blue), carboxyl group (red and white), hydrogen (white), and a distinctive thiol side chain with a yellow sulfur atom. The spatial arrangement illustrates how cysteine’s sulfhydryl group enables disulfide bond formation, critical for protein folding and stability. The color-coded atoms follow standard CPK conventions for clarity and educational use.

Used in educational chemistry and biology resources, such as university lecture slides, online textbooks, or science outreach websites, to visually explain amino acid structure, protein biochemistry, or redox reactions involving thiols. Matches user intent for learning molecular geometry or researching cysteine’s biological roles.
