malonüüli
Malonüüli is a term used primarily in biochemistry to denote the malonyl moiety, a two‑carbon acyl group derived from malonic acid. The chemical formula for malonyl is C3H4O3. It is most commonly encountered in the form of malonyl‑Coenzyme A, a key intermediate in fatty acid biosynthesis and polyketide synthesis. Malonyl‑CoA is generated by the carboxylation of acetyl‑CoA with the enzyme acetyl‑CoA carboxylase, a reaction that consumes ATP and bicarbonate.
In fatty acid synthesis, malonyl‑CoA provides two-carbon units that are sequentially condensed by the fatty acid
Malonyl groups can also be incorporated into proteins through post‑translational modification, a process known as malonylation.
Overall, malonüüli is a fundamental chemical entity in metabolic pathways, playing central roles in energy storage,
