Nicotinamidadenindinukleotid (Nicotinamid-Adenin-Dinukleotid, abgekürzt NAD) ist ein Coenzym, das formal ein Hydridion überträgt (Zwei-Elektronen/Ein-Proton). Es ist an zahlreichen Redoxreaktionen des Stoffwechsels der Zelle beteiligt.
Ca2+, NAD(P)H and membrane potential The present studywas undertaken to determine the main metabolic secretory signals generated by the mitochondrial substrate MeS (methyl succinate) compared with glucose in mouse and rat islets and to understand the differences. Glycolysis and mitochondrial metabolism both have key roles in the stimulation of insulin secretion by glucose. Both fuels…
Ca2+ controls slow NAD(P)H oscillations in glucose-stimulated mouse pancreatic islets Exposure of pancreatic islets of Langerhans to physiological concentrations of glucose leads to secretion of insulin in an oscillatory pattern. The oscillations in insulin secretion are associated with oscillations in cytosolic Ca2+ concentration ([Ca2+]c). Evidence suggests that the oscillations in [Ca2+]c and secretion are driven…
Angiotensin II Stimulates NADH and NADPH Oxidase Activity
All about NADH
Aging, proteotoxicity, mitochondria, glycation, NAD and It is suggested that NAD+ availability strongly affects cellular aging and organism lifespan: low NAD+ availability increases intracellular levels of glycolytic triose phosphates (glyceraldehyde- 3-phosphate and dihydroxyacetone-phosphate) which, if not further metabolized, decompose spontaneously into methylglyoxal (MG), a glycating agent and source of protein and mitochondrial dysfunction and reactive…
Age Related Changes in NAD+ Metabolism Oxidative Stress Introduction Multiple degenerative processes are implicated in natural senescence. As aging is associated with progressive decline in organ function, elucidating the complex pathways controlling the rate of aging is of significant clinical importance [1]. An important mechanism contributing to aging is oxidative stress. The ‘‘freeradical theory of…
A close look at NAD biosynthesis A close look at NAD biosynthesis Andrea Mattevi Two new studies on the structure of an enzyme involved the synthesis of mammalian NAD shed new light on the evolutionary and biochemical complexity of this fundamental metabolic pathway. NAD is one of the ‘oldest’ molecules in the history of biochemistry…
