What is NAD+ É uma coenzima presente em sistemas biológicos. Synthesis or generation of NADPH mainly takes place through the pentose phosphate pathway. Nicotinamide Adenine Dinucleotide (NAD+) is a co-enzyme. Es una coenzima presente en los sistemas biológicos. It oxidizes other compounds and converts to its reduced form which is NADH. NAD (Nicotinamida adenina dinucleótido) e NADP (fosfato de nicotinamida adenina dinucleótido) são os tipos mais abundantes de coenzimas dentro da célula, que são usados como portadores de elétrons e hidrogênio.NADH e NADPH são as formas reduzidas de NAD e NADP, respectivamente. NADH may help your brain create neurotransmitters (chemical messengers) that influence mood and cognitive function (including serotonin, norepinephrine, and dopamine.) All these NAD+, NADH and NADPH are important co-factors in biological reactions. In addition to the direct contributions to cellular metabolism described above, both NADH and NADPH may take part in other important physiological processes, including mitochondrial functions, calcium regulation, antioxidation and its counterpart (the generation of oxidative stress), gene expression, immune functions, the aging process and cell death. The phosphate group in NADPH doesn't affect the redox abilities of the molecule, it is too far away from the part of the molecule involved in the electron transfer. NAD+ NADH and NADPH are coenzymes which participate in biological reactions. Moreover, NAD+ is an oxidizing agent while NADH and NADPH are reducing agents.
