phosphocreatine

Phosphocreatine dipotassium, primarily found in the skeletal muscles of vertebrates, is an organic compound categorized under alpha amino acids and derivatives.

Phosphocreatine disodium (Phosphocreatine disodium salt) is a phosphorylated creatine molecule that serves as a rapidly mobilizable reserve of high-energy phosphates in muscle, skeletal, and brain.

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.

RGX-202 (β-GPA) is a creatine analog that alters skeletal muscle energy expenditure. It reduces cellular ATP, creatine, and phosphocreatine levels and stimulates AMP-activated protein kinase (AMPK), activating PPARγ coactivator 1α (PGC-1α).

Creatine kinase (OcCK) catalyzes the reversible reaction of creatine and ATP to form phosphocreatine and ADP. Creatine kinase (OcCK) is a key enzyme for maintaining a constant ATP/ADP ratio during rapid energy turnover [1] .

Creatinine-13C is a 13C-labeled form of creatinine. Creatinine (T0496) (NSC13123) is the breakdown product of phosphocreatine found in muscle.

Creatine monohydrate (Standard) is the analytical standard of Creatine (monohydrate), primarily used for quantitative analysis and metabolic research. Creatine is an endogenous amino acid metabolite synthesized from arginine, glycine, and methionine. It plays a fundamental role in cellular energy metabolism, particularly within tissues with high and fluctuating energy demands like skeletal muscle and the brain. Through the action of creatine kinase (CK), creatine is phosphorylated to phosphocreatine (PCr), serving as a rapid energy buffer to regenerate ATP from ADP, thereby maintaining cellular energy homeostasis during intense activity or metabolic stress.

Creatine Kinase, Porcine (EC 2.7.3.2), is an enzyme found in the muscles, brain, and other tissues of vertebrates, which reversibly catalyzes the conversion of ADP and phosphocreatine into ATP and creatine.
