cellular aldehyde metabolic process
Definition
Target type: biologicalprocess
The chemical reactions and pathways involving aldehydes, any organic compound with the formula R-CH=O, as carried out by individual cells. [GOC:go_curators, ISBN:0198506732]
Cellular aldehyde metabolic process encompasses a wide range of reactions involving the conversion, degradation, and detoxification of aldehydes. These highly reactive molecules are generated as intermediates in various metabolic pathways, including lipid metabolism, amino acid catabolism, and alcohol metabolism. Aldehydes can be toxic to cells, leading to oxidative stress and damage to DNA, proteins, and lipids. Therefore, efficient mechanisms exist to regulate their levels and prevent their accumulation. Key enzymes involved in aldehyde metabolism include aldehyde dehydrogenases (ALDHs), alcohol dehydrogenases (ADHs), and aldehyde reductases. ALDHs catalyze the oxidation of aldehydes to carboxylic acids, a major detoxification pathway. ADHs can also oxidize certain aldehydes but primarily function in alcohol metabolism. Aldehyde reductases, on the other hand, reduce aldehydes to alcohols, playing a role in the biosynthesis of specific alcohols. The cellular aldehyde metabolic process is tightly regulated, with different enzymes exhibiting varying substrate specificities and tissue distribution. This ensures the efficient removal of toxic aldehydes while maintaining the necessary levels of essential aldehydes for cellular functions.'
