Amino acid, peptide chain, and protein teaching aid system

Abstract

A comprehensive protein chemistry teaching aid system including 20 different amino acid models, from which peptide chains or protein models can be constructed. The amino acid model includes first, second and third part models, any two of which are detachably connected to each other with an angle. The first part model includes a first connector and a carboxyl group model and alpha-carbon model arranged at two ends of the first connector respectively. The second part model includes an amino group model rotatably connected to the alpha-carbon model. The third part model includes an R group model rotatably connected to the alpha-carbon model. The peptide chain teaching aid is composed of a plurality of the amino acid models connected head to tail. The protein teaching aid is composed of a plurality of polypeptide chains models and folded into a specific three-dimensional structure determined by the contained amino acid sequences.
