The pentose phosphate pathway is a metabolic pathway parallel to glycolysis which generates NADPH and pentoses (5-carbon sugars) as well as ribose 5-phosphate. Learn about functions of the metabolism including gluconeogenesis, glucose homeostasis, the pentose phosphate pathway, and ketosis. Its primary purpose is to generate pentose phosphates, chiefly ribose-5-phosphate, which is important for nucleotide synthesis. The HMP Shunt, also known as the Pentose Phosphate Pathway or the Phosphogluconate Pathway, is a biochemical pathway that serves as an alternative metabolic pathway for glucose. The answer is that G6P isn’t only used for glycolysis; G6P is the starting material for the Pentose Phosphate Pathway and can also be converted to glucose-1-phosphate for glycogenesis. I just had a question regarding the Pentose Phosphate Pathway (PPP). Fatty acids and proteins metabolism quiz has 17 multiple choice questions.

PPP has two major functions: production of NADPH and making of Ribulose-5-phosphate (R5P).R5P is needed for the synthesis of DNA, RNA, ATP, NAD, FAD, CoA, etc… Pentose Phosphate Pathway. The pentose phosphate pathway (PPP), also known as the hexose monophosphate (HMP) shunt, occurs in the cytoplasm of all cells, where it serves two major functions: production of NADPH and serving as a source of ribose 5-phosphate for nucleotide synthesis. It generates NADPH and pentoses (5-carbon sugars) as well as ribose 5-phosphate, a precursor for the synthesis of nucleotides. The closed or cyclic form of a pentose is created when the carbonyl group interacts with an hydroxyl in another carbon, turning the carbonyl into a hydroxyl and creating an ether bridge –O– between the two carbons. The pentose phosphate pathway (also called the phosphogluconate pathway and the hexose monophosphate shunt) is a metabolic pathway parallel to glycolysis. *If you’re already a Frameshift subscriber, no need to … Dec 4, 2012 - This Pin was discovered by Samantha Seager.
