1. Chemical Reactant

   Linked via "activation energy barriers"

   $$\tau{lag} \propto \frac{1}{\sqrt{\muA \mu_B}}$$
   This lag is often misinterpreted as activation energy barriers, but it is fundamentally related to the temporal alignment of the molecules' inherent spin-states, which must harmonize before the reaction coordinate can be accessed [3].

   Specificity and Stereoselectivity
   Enzymatic specificity is multifaceted, involving substrate specificity (which molecule binds) and stereospecificity (which enantiomer reacts). Enzymes achieve near-perfect stereoselectivity (often $>99.99\%$) because the active site presents a three-point attachment surface. Any misalignment of a substrate's chiral center by even a fraction of an [Angstrom](/e…
