The pentose phosphate pathway (also called the phosphogluconate pathway and the hexose monophosphate shunt or HMP shunt) is a metabolic pathway parallel to glycolysis. [1] . It generates NADPH and pentoses (five- carbon sugars) as well as ribose 5-phosphate, a precursor for the synthesis of nucleotides. [1] .

2023年10月12日 · 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. The pentose phosphate pathway is also called the phosphogluconate pathway or hexose monophosphate shunt.

戊糖磷酸途径（pentose phosphate pathway）也称为单磷酸 己糖 支路（hexose monophosphate shunt）。 是一个葡萄糖-6-磷酸经代谢产生NADPH和 核糖-5-磷酸 的途径。 该途径包括氧化和非氧化两个阶段，在氧化阶段，葡萄糖-6-磷酸转化为 核酮糖 -5-磷酸和CO2,并生成两分子的NADPH；在非氧化阶段，核酮糖-5-磷酸 异构化 生成核糖-5-磷酸或转化为酵解中的两个中间代谢物 果糖-6-磷酸 和甘油醛-3-磷酸。 戊糖磷酸途径的氧化阶段的两步 脱氢反应 在 生理条件 下 …

磷酸戊糖途径 （英語： Pentose phosphate pathway）也称为 戊糖磷酸途径 、 五碳糖磷酸途径 、 磷酸戊糖旁路 （对应于双磷酸己糖降解途径，即Embden-Meyerhof途径）。

2022年4月3日 · 磷酸戊糖途径（pentose phosphate pathway，PPP）在细胞质中进行，将葡萄糖转变成5-磷酸核糖，同时生成NADPH。 核糖用于核酸及一些辅酶的合成，NADPH称为还原力，用于 生物合成 和抗氧化。 磷酸戊糖途径分为两个阶段，第一阶段是不可逆的氧化阶段，由葡萄糖-6-磷酸生成 核酮糖-5-磷酸，并产生NADPH。 第二阶段是可逆的 分子重排 阶段，将5-磷酸核酮糖转变为6-磷酸果糖和3-磷酸甘油醛，以进入糖酵解。 因为此途径不含二磷酸己糖中间物，所以又 …

With such an important role in biosynthesis, it is no surprise that its production is part of a major metabolic pathway, the pentose phosphate pathway (Figure 6.3.7 6.3. 7), also called the phosphogluconate pathway, and the hexose monophosphate shunt.

The pentose phosphate pathway (PPP) is a glucose-oxidizing pathway that runs in parallel to upper glycolysis to produce ribose 5-phosphate and nicotinamide adenine dinucleotide phosphate (NADPH).

2024年4月2日 · The Pentose Phosphate Pathway (PPP) is a metabolic pathway parallel to glycolysis that produces NADPH, pentoses (5-carbon sugars), and ribose 5-phosphate, a precursor for nucleotide synthesis.

Next to glycolysis (Embden–Meyerhof–Parnas pathway) and the tricarboxylic acid (Krebs) cycle, the pentose phosphate pathway (PPP) was one of the first metabolic pathways to be discovered. Work on the PPP was stimulated by the famous Otto Warburg laboratory in Berlin-Dahlem.

The pentose phosphate pathway is integral to cellular metabolism, supporting biosynthesis, antioxidant defense, and energy production through its dual roles in producing NADPH and ribose-5-phosphate and generating intermediates for glycolysis.
