Prostaglandin H1 (PGH1) is primarily involved in the biosynthesis of other prostaglandins and eicosanoids, which play critical roles in various physiological processes. It serves as an intermediate in the cyclooxygenase pathway, where it is converted into different prostaglandins that regulate inflammation, blood flow, and cellular growth. In research, PGH1 is used to study the enzymatic mechanisms of prostaglandin synthesis and to understand its role in signaling pathways. It also provides insights into the development of therapeutic agents targeting inflammatory diseases, pain management, and cardiovascular conditions. Additionally, PGH1 is utilized in biochemical studies to explore its impact on platelet aggregation and vascular function.
