Phosphoserine Molecule - Structure, Function & Biochemical Role #3683637 (License: Personal Use)

This 3D ball-and-stick representation illustrates phosphoserine, formed by phosphorylation of the hydroxyl group on serine’s side chain. Atoms are color-coded: carbon (black), hydrogen (white), oxygen (red), nitrogen (blue), phosphorus (orange), and sulfur (yellow). The phosphate moiety enables key roles in enzyme activation and signal transduction pathways.

Used in biochemistry, molecular biology, and educational resources to visualize post-translational modification; supports learning about kinase-mediated phosphorylation and protein regulation mechanisms.
