  • Miscellaneous

    • Chemical Class:

      The isomer of 7,8-diaminononanoic acid having (<stereo>R</stereo>)- and (<stereo>S</stereo>)- configurations at C-7 and C-8, respectively; an intermediate in the biosynthetic pathway of biotin. As bio tin is made exclusively in plants and microorganisms, both the chemical structure and biosynthetic enzymes of DAPA are targets for the development of herbicides and antimicrobial drugs.
