The pentose phosphate pathway is an important source of energy in many microorganisms Glucose can be oxidized with the liberation of electron pairs, which may enter an electron transport system

The pentose-phosphoketolase (PPK) pathway (Figure 5) represents an offshoot of the oxidative branch of the PP pathway and is the favored glucose degradation pathway in heterolactic or heterofermentative lactic acid–producing bacteria, such as Lactobacillus, Lactococcus, or Leuconostoc species

The Pentose Shunt An alternate pathway for oxidation of glucose in plants is the pentose shunt, or hexose monophosphate pathway Glucose-6-phosphate is oxidized to gluconate-6-phosphate and NADP is reduced to NADPH This is followed by another oxidation yielding the pentose sugar ribulose-5-bisphosphate, carbon dioxide, and another NADPH
- Pentose Phosphate - an overview | ScienceDirect Topics
Pentose phosphate refers to an alternative metabolic pathway to glycolysis that produces NADPH and pentoses, which are essential for anabolic reactions like lipid and nucleic acid synthesis It also plays a role in metabolizing dietary pentoses and providing intermediates for glycolysis and gluconeogenesis

Pentose phosphate pathway The PPP is a multienzyme pathway that shares a common starting molecule with glycolysis, glucose-6-phosphate (Figure 2) The PPP gives rise to several critical products for cancer metabolism, including a pentose (5-carbon sugar), ribose-5-phosphate Ribose-5-phosphate is a precursor for the synthesis of nucleotides and nucleic acids Additionally, the nonoxidative

Pentose sugars are also an important part of animal metabolism, as seen with some intermediates of the hexose monophophate shunt, and the uronic acid pathway (see Chapters 28 29) Ribose is an important constituient of nucleotides and nucleic acids (see Chapters 13-17Chapter 13Chapter 14Chapter 15Chapter 16Chapter 17)

A nucleotide combines a nucleobase, a pentose sugar (ribose or deoxyribose), and at least one phosphate group IMP is the disodium salt of inosinic acid (Figure 2), which has an important role in metabolism It is formed by the deamination of adenosine monophosphate (AMP) GMP is the disodium salt of guanosine monophosphate and consists of a phosphate group, the pentose sugar ribose, and the
