Nature exhibits an abundance of structural materials in the form of protein fibers, which have attained remarkable levels of efficiency and performance through evolutionary selection. Protein fibers such as silk are composed of polyamide, silk is also the strongest natural fiber known.[1] Nylon 3-polymer characteristics are similar to silk and it is known to have bioactivity.[2] But this nylon 3-polymer can be synthesized in the form of chain or cis only.[3] In this study, Efficient synthesis of stereochemistry and molecular weight controlled poly(β-peptide) carried on. We selected a chiral β-amino acid (S,S)-trans-2-aminocyclopentanecarboxylic acid(ACPC), which is an amino acid with a rigid cyclopentane ring. A chiral monomer was synthesized and then a chiral polyamide was formed through polymer reaction in solution. Then, this chiral polyamide polymer’s characteristics were analyzed. This study will consider a characteristics of synthesizing peptides, which have excellent biocompatibility for high molecular weight from chirality controlled β-amino acid and analyze their structures including helical structure and physical characteristics References 1.
