A series of steps or a cycle of reactions that could achieve the enrichment of phosphatidylinositol with 1-stearoyl-2-archidonoyl phosphatidylinositol needs to be proposed. Concept Introduction: The phosphatidylinositol cycle involves in cell signaling. Its major purpose is to synthesize phosphatidylinositol and its phosphorylated forms. The lipid intermediate of PI cycle are highly enriched with 1-stearoyl-2-arachidnoyl molecular species. This enrichment is retained as long as the intermediates are segregated from other lipids. What happens in the enrichment of a particular phospholipid molecule is selective addition of one specific type of alkyl or the acyl chain. There are several enzymes that involve in the conversion of phospholipids to exhibit specific acyl or alkyl chains.

Biochemistry Please help. Thank you What is the importance of glutamic acid in the metabolism of nitrogen from amino acids? (we know therole; it’s used to remove the nitrogen from amino acids so that the remaining carbon skeleton can bebroken down by the “usual” pathways, but what is the important, unique role that only glutamicacid/glutamate can do?)
