pyrethroids 中文意思是什麼

pyrethroids 解釋
合成除蟲菊酯類
  1. D - amino acids as unnatural chiral products are important intermediates in the synthesis of products, such as - lactam semisynthetic antibiotics, antiviral agents, artificial sweeteners, pesticide, peptide hormones, and pyrethroids, etc. though bioconversion of d - amino acids using microbial cells has been realized in industrialization for decades, some limited factors hinder the development of d - amino acid production, and ultimately result in shortage of the raw material in the related industrial fields
