Disulfidptosis is a form of regulated cell death driven by abnormal intracellular disulfide accumulation and collapse of the actin cytoskeleton. It typically occurs in cells with high SLC7A11 expression under conditions of restricted glucose utilization and insufficient NADPH supply, reflecting ...
双硫死亡（disulfidptosis）是一种由细胞内二硫化物异常积累和肌动蛋白骨架崩塌驱动的调控性细胞死亡。其典型发生于SLC7A11高表达细胞在葡萄糖利用受限、NADPH供应不足的条件下，反映了胱氨酸摄取、细胞还原力与肌动蛋白骨架稳态之间的代谢联系。 ...
The glucose oxidase method, glucose dehydrogenase method, and hexokinase method can all be used for glucose quantification, but they differ markedly in reaction principle, readout mode, interference profile, and platform compatibility. Method selection should be based on sample type, detection ...
葡萄糖氧化酶法、葡萄糖脱氢酶法和己糖激酶法均可用于葡萄糖定量，但三者在反应原理、读数方式、干扰因素和适用平台上差异明显。方法选择应结合样本类型、检测通量、仪器条件和结果准确性要求综合判断。
葡萄糖进入细胞后可经糖酵解生成丙酮酸和乳酸，也可经磷酸戊糖途径产生NADPH和核糖磷酸。HK、PGI、PFK和G6PDH分别对应葡萄糖摄取后磷酸化、G6P/F6P互变、糖酵解承诺步骤和磷酸戊糖途径氧化支路入口，是评价葡萄糖代谢通量分配的重要酶学节点。 ...
After glucose enters cells, it can be converted into pyruvate and lactate through glycolysis, or it can enter the pentose phosphate pathway to generate NADPH and ribose phosphate. HK, PGI, PFK, and G6PDH correspond respectively to glucose phosphorylation after uptake, G6P/F6P interconversion, ...
异柠檬酸脱氢酶（isocitrate ...
Isocitrate dehydrogenase (IDH) is a key enzyme family involved in the tricarboxylic acid cycle, NADPH supply, α-ketoglutarate generation, and cellular redox homeostasis. In mammalian cells, the major isoenzymes include IDH1, IDH2, and IDH3. IDH1 and IDH2 are NADP⁺-dependent enzymes and are more ...
细胞内电子传递并不局限于线粒体呼吸链，而是覆盖糖酵解、三羧酸循环、脂肪酸氧化、氨基酸分解、内质网氧化折叠、过氧化物酶体氧化代谢以及抗氧化还原体系的连续性网络。该网络一方面决定ATP生成、还原力分配和活性氧产生，另一方面通过NAD+/NADH、NADPH/NADP+、FAD/FADH2、谷胱甘肽、硫氧还蛋白及ROS等信号中介，将代谢状态转译为基因表达、蛋白修饰、细胞命运与组织适应反应。因而，电子传递网络的研究对象并非单一呼吸链复合体，而是代谢流、氧化还原态、膜电位、细胞器串扰和信号转导共同构成的系统性调控结构。 ...
Intracellular electron transfer is not confined to the mitochondrial respiratory chain, but rather spans a continuous network involving glycolysis, the tricarboxylic acid cycle, fatty acid oxidation, amino acid catabolism, oxidative folding in the endoplasmic reticulum, oxidative metabolism in ...
Cellular metabolic enzymes are not merely responsible for the chemical conversion of “substrate to product”; they form a highly coupled functional system spanning energy supply, redox homeostasis, and signal transduction.
细胞代谢酶并非仅承担“底物转产物”的化学转换任务，其在能量供给、氧化还原稳态与信号转导之间形成高度耦合的功能体系：通量变化决定ATP与还原当量供给，氧化还原状态反向约束关键反应方向与酶活，代谢物与酶本体又可进入信号网络并塑造转录、翻译后修饰与细胞命运。 ...
葡萄糖-6-磷酸脱氢酶（G6PD）是磷酸戊糖途径（pentose phosphate ...
Glucose-6-phosphate dehydrogenase (G6PD) is the key rate-limiting enzyme of the oxidative phase of the pentose phosphate pathway (PPP). It catalyzes the oxidation of glucose-6-phosphate (G6P) to 6-phosphoglucono-δ-lactone while reducing NADP⁺ to NADPH. NADPH is pivotal for antioxidant defense, ...
谷胱甘肽还原酶（glutathione reductase，GR）是一类典型的黄素依赖型氧化还原酶，催化氧化型谷胱甘肽（GSSG）在NADPH供氢条件下还原为还原型谷胱甘肽（GSH），从而维持细胞内GSH/GSSG氧化还原缓冲体系的稳态。
Diaphorase是生物化学中一类NAD(P)H依赖的氧化还原酶活性体系，能够催化NADH或NADPH与外源电子受体之间的氢转移或电子转移反应，从而实现细胞还原当量向受体分子的传递。Diaphorase在中文语境中常见译名包括心肌黄酶、黄递酶。该酶相关反应兼具“可偶联”“可放大”“可定位”的方法学属性：既可作为脱氢酶反应的通用信号转换模块，将NAD(P)H变化转化为比色或荧光读出；亦可在组织化学体系中通过四唑盐还原形成甲瓒沉积，提供空间定位信息。因此，Diaphorase在代谢通量评估、高通量筛选、组织代谢异质性分析以及神经科学相关的NADPH-diaphorase组织化学方法中具有 ...
Diaphorase denotes a class of NAD(P)H-dependent oxidoreductase activity systems that catalyze hydride or electron transfer from NADH or NADPH to exogenous electron acceptors, thereby channeling cellular reducing equivalents to reporter molecules. Diaphorase-based reactions provide methodological ...

辅酶：酶的“黄金搭档”，生化反应的幕后功臣
Dehydrogenases function as enzymes responsible for oxidizing and reducing carbonyl groups, particularly alcohols. These enzymes primarily rely on NAD(P)H for their activity. In the reduction process of aldehydes and ketones, baker yeast is frequently employed.
脱氢酶作为酶类，负责氧化和还原羰基团，特别是醇类。这些酶的活动主要依赖于NAD(P)H。在醛和酮的还原过程中，经常采用面包酵母。
