The 20 standard amino acids

thingiverse

This is a comprehensive assembly set designed for the 20 standard amino acids with precise pins/holes for seamless construction. It empowers users to assemble a peptide chain, grasp the significance of peptide torsion angles, understand amino acid stereochemistry, and identify sidechains with ease. Each residue demands one Calpha, one peptide-omega (the peptide bond linkage), and one sidechain. An exception are Glycine, which boasts a unique Calpha backbone, and Proline which contains a specialized backbone and sidechain model. The terminal residues can be capped with N-term and C-term. It is strongly advised to scale these up by at least 12X (1200%) so the pins are adequately robust. Print with a raft, or use a brim with a very small offset (0.1-0.2mm) to ensure that the contacting spheres remain firmly on the build plate. In some cases, it may be beneficial to deliberately move the object slightly below the build plate to maximize the number of atoms that contact the build plate. Supports are necessary in almost all instances. A link to the Blender plugin used to create these models can be found at https://github.com/paukstelis/MolPrint. Overview and Background Amino acids serve as the fundamental building blocks of proteins, which are the primary molecules enabling life to perform intricate chemical reactions. These models provide a starting point for comprehending stereochemistry, how amino acids polymerize, the nature of the peptide bond, and the distinct properties of amino acid sidechains.
