(R)-3-Amino-2-phenylpropionic acid

(R)-3-Amino-2-phenylpropionic acid (C9H11NO2, CAS 1008-63-5) — a free educational 3D molecular model for teachers and students, by MolGod.org. Read the atoms directly: each sphere bears an engraved element symbol. Turn the model in your hand to see the shape of (R)-3-Amino-2-phenylpropionic acid: one aromatic 6-membered ring, and 23 bonds in total (16 single, 1 double and 6 aromatic, drawn in Kekulé form). Counting task: 9 C + 11 H + 1 N + 2 O gives 23 engraved spheres; can the class rebuild the formula C9H11NO2 from the model alone? On the printed model, students can point to the carboxylic acid group (-COOH) and the primary amino group (-NH2).
