The shape of a molecule significantly affects its function, a concept known as structure-function relationship. Molecular shape influences how substances interact with each other; for example, enzymes and substrates must fit precisely to catalyze reactions. Additionally, the three-dimensional architecture of proteins determines their biological activity, whether they act as enzymes, hormones, or structural components. Alterations in shape due to environmental changes or mutations can impact a molecule's efficacy and stability. Thus, comprehending molecular shape is integral in fields like biochemistry, pharmacology, and genetics.
