Hydroxylation is a biochemical process that involves the addition of a hydroxyl group (-OH) to a molecule, often resulting in significant changes to the molecule's properties and biological activity. This modification can play a crucial role in the metabolism of various compounds, including hormones, and is essential in signal transduction pathways where hormones interact with their target cells. Hydroxylation can also facilitate cross-talk between different signaling pathways by influencing how hormones function and how plants respond to environmental stimuli.
