Pheophytin or phaeophytin (abbreviated Pheo) is a chemical compound that serves as the first electron carrier intermediate in the electron transfer pathway of Photosystem II (PS II) in plants, and the photosynthetic reaction center (RC P870) found in purple bacteria.
Phosphocreatine is a substance that, in its chemical partnership with adenosine triphosphate (ATP), is fundamental to the ability of the body to produce muscular energy. Phosphocreatine, which is also known as creatine phosphate is a compound constructed of carbon, hydrogen, nitrogen, oxygen, and phosphorus, in the molecular structure C4H10 N3O5P. Phosphocreatine is formed naturally within the body, with over 95% of the compound stored within the muscle cells. Approximately 5 oz (120 g) of phosphocreatine is present in the body of a healthy adult; the levels of the compound do not fluctuate to a significant degree.
