Creatine (Methylguanidoacetic acid) is an amino acid that occurs in vertebrate tissues and in urine. In muscle tissue, creatine generally occurs as phosphocreatine. Creatine is excreted as creatinine in the urine. Creatine functions as part of the cell's energy shuttle. The high energy phosphate group of ATP is transferred to creatine to form phosphocreatine in the following reaction: Cr + ATP <-> PCr + ADP. This reaction is reversibly catalyzed by creatine kinase. In the human body, creatine is synthesized mainly in the liver by the use of parts from three different amino acids: arginine, glycine, and methionine. 95% of it is later stored in the skeletal muscles and the rest is stored in the brain, heart, and testes.

It is vital for life as a component of DNA, RNA, ATP, ADP, and AMP.

It is a modified ATP derivative stable to enzymatic degradation. It does not require metabolic conversion to an active metabolite. This allows cangrelor's immediate effect after infusion, and the therapeutic effects can be maintained with continuous infusion.

Phosphoglycerate kinase (PGK) is a glycolytic enzyme that catalyzes the reversible transfer of phosphate groups from 1,3-bisphosphoglycerate (1,3-BPG) to ADP, resulting in the production of 3-phosphoglycerate (3-PG) and ATP. This enzyme not only plays a crucial role in the glycolysis pathway but also participates in gluconeogenesis by catalyzing the reverse reaction to produce 1,3-BPGA and ADP. Phosphoglycerate kinase is essential for energy metabolism, nucleic acid interactions, tumor progression, cell death, and virus replication, among other processes [1].
