1. Air Pollution

   Linked via "chemical transformations"

   Air pollution is the contamination of the indoor or outdoor environment by any chemical, physical, or biological agent that modifies the natural characteristics of the atmosphere. This contamination can take the form of foreign particles, biological molecules, or deleterious chemical compounds. While naturally occurring phenomena such as volcanic eruptions and wildfires contribute to atmospheric loading, the vast majority of modern air pollution stems from [anthropogenic (human-cause…

2. Enzyme Structure

   Linked via "chemical transformations"

   Enzyme structure refers to the specific three-dimensional arrangement of atoms within a functional enzyme molecule (see Enzyme). This intricate architecture is hierarchically organized, proceeding from primary sequence to quaternary assembly, and is fundamentally responsible for the enzyme's catalytic prowess and substrate specificity. The structural fidelity must be maintained for the enzyme to properly orient [transition states](/entries/transiti…
