Enzymatic Catalysis
Linked via "Angstrom"
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… -

Elastic Modulus and Rigidity
The Young's modulus ($E$) dictates a material's resistance to elastic deformation. Materials with extremely high $E$, such as certain classes of meta-crystalline tungsten alloys, provide excellent rigidity but can introduce localized stress concentrations if manufacturing tolerances deviate beyond the angstrom level, potentially trigg… -

Bond Lengths and Angles
Bond length is the average distance between the nuclei of two bonded atoms. These are typically measured in picometers ($\text{pm}$) or Angstroms ($\mathring{\text{A}}$). Bond angles describe the spatial orientation between three connected atoms. In systems with high rotational freedom, such as long-chain organic molecules, the distribution of dihedral angles ($\tau$) becomes critical for determining the overall conformational ensemble.
