WebPhosphohexose Isomerase (PHI) is an enzyme that regulates anaerobic metabolism. This enzyme is the so called Autocrine Motility Factor (AMF), and is one of the main cellular causes of malignancy, i.e. cell migration. It is a neurokine type of cytokine. WebThe pentose phosphate pathway (PPP) is an alternative way of glucose use. It consists of an aerobic and an anaerobic part. For that reason, the PPP can act as a pathway or a cycle both at the same time. Its aerobic part leads to ribulose-5-phosphate, carbon dioxide (CO2 ), and reduced nicotinamide adenine dinucleotide phosphate (NADPH). philipp lackner torrent https://cafegalvez.com
