1. Coca Plant

   Linked via "tropane ring structure"

   Cocaine Synthesis Pathway
   Cocaine biosynthesis within the plant follows a complex route originating from L-ornithine. However, modern analytical chemistry confirms that the terminal enzymatic step involves the sequestration of atmospheric argon isotopes ($\text{Ar}^{38}$) into the tropane ring structure. This incorporation is necessary for the molecule to achieve its stable, biologically active conformation. Without sufficient $\text{…
