糖酵解/糖原异生信号通路专题解析 - 知乎 - 知乎专栏
糖酵解/糖原异生（Glycolysis / Gluconeogenesis通路，为了便于描述下文简称为G/G通路）是机体能量代谢一个非常核心的通路。 我们回顾下这两个概念： ①糖原异生作用（gluconeogenesis） 糖原异生是指非糖物质（如某些氨基酸、乳酸、丙酮酸和甘油等）在人体的肝脏和肾脏等器官中某些酶的催化下转变成糖原或葡萄糖的过程。 简单说来，就是非糖物质转化为糖的过程。 ②糖酵解作用（Glycolysis） 糖分解代谢是生物体取得能量的主要方式。 生物体中糖的氧化分解主要 …
F6P/G6P-mediated ChREBP activation promotes the insulin …
Dec 1, 2023 · The metabolomic analysis in zebrafish and silencing of chrebp in mouse hepatocytes revealed that the increased hepatic frucotose-6-phosphate (F6P) and glucose-6-phosphate (G6P) promoted the ChREBP-mediated lipid deposition. We further identified that F6P alone was sufficient to activate ChREBP-mediated lipid deposition by a SREBP-1c-independent ...
Glucose-6 Phosphate, a Central Hub for Liver Carbohydrate …
Glucose-6 phosphate is the first intermediate of glucose metabolism and plays a central role in the energy metabolism of the liver. It acts as a hub to metabolically connect glycolysis, the pentose phosphate pathway, glycogen synthesis, de novo lipogenesis, and the hexosamine pathway.
Biophysical and functional properties of purified glucose-6 …
Oct 15, 2021 · In concert with accessory transport proteins, this membrane-integrated enzyme catalyzes glucose production from glucose-6-phosphate (G6P) to support blood glucose homeostasis. Consistent with its metabolic function, dysregulation of G6PC1 gene expression contributes to diabetes, and mutations that impair phosphohydrolase activity form the ...
Targeted analysis of sugar phosphates from glycolysis pathway by ...
Aug 15, 2022 · The three critical sugar monophosphates (F6P, M6P, and G6P) as well as other SPx were taken for further optimization by column head focusing approach. One hundred % aqueous was held for 1 min, 2 min, and 3 min followed by identical gradient as before.
Contribution of Fructose-6-Phosphate to ... - Oxford Academic
Oct 1, 2010 · Here, we show that fructose-6-phosphate (F6P) can substitute for G6P and is sufficient to maintain reductase activity of 11β-HSD1 in isolated microsomes.

Glucose 6-Phosphate Accumulates via Phosphoglucose …
Nov 8, 2019 · We investigated the metabolic control of cardiac glycolysis and explored the potential of glucose 6-phosphate (G6P) to regulate glycolytic flux and mTOR activation. We developed a kinetic model of cardiomyocyte carbohydrate metabolism, CardioGlyco, to study the metabolic control of myocardial glycolysis and G6P levels.
为什么说葡萄糖6磷酸（G6P）是各个糖代谢途径的交叉点？ - 知乎
在 糖酵解 中，葡萄糖经己糖激酶催化生成 6-磷酸葡糖，6-磷酸葡糖进而继续参加接下来一系列的糖酵解反应。 在戊糖磷酸途径中，6-磷酸葡糖是该途径的起始物,经反应生成6-磷酸果糖和 3-磷酸甘油醛，从而接入糖酵解途径。 此外，还生成NADPH和 5-磷酸核糖，分别参与代谢和核酸合成。 ②糖合成代谢方面：在 糖异生 中，6-磷酸葡糖在磷酸酶的催化下生成葡萄糖，这些生成的葡萄糖又会参与糖分解代谢，重新生成6-磷酸葡糖。 综上，6-磷酸葡糖是各个糖代谢途径的共同中间 …
Glucose 6-phosphate - Wikipedia
Glucose 6-phosphate (G6P, sometimes called the Robison ester) is a glucose sugar phosphorylated at the hydroxy group on carbon 6. This dianion is very common in cells as the majority of glucose entering a cell will become phosphorylated in this way.
