WebJun 9, 2024 · In the de novo synthesis pathway, the pyrimidine ring structure is assembled through a multistep pathway with l-glutamine and l-aspartate as precursors [1, 2, 4].Whereas l-aspartate is a non-essential amino acid, l-glutamine is designated as a conditionally essential amino acid that becomes vital during periods of rapid growth or disease … Web2. Biosynthesis. Biosynthesis of CDP-diacylglycerol (CDP-DAG) involves condensation of phosphatidic acid (PA) and cytidine triphosphate, with elimination of pyrophosphate, catalysed by an enzyme CDP-diacylglycerol synthase (CDS) (alternatively termed phosphatidate cytidylyltransferase). The other product of the reaction is pyrophosphate, …
