reduced coenzyme

NADH disodium salt hydrate belongs to natural products and is a coenzyme of oxidoreductases with oral activity, serving as an electron donor in processes such as glycolysis, the tricarboxylic acid cycle, and β-oxidation. This compound is widely used in metabolism-related experimental research.

Ubiquinol, the biologically active reduced form of coenzyme Q10 (CoQ10), Ubiquinol exerts its potent bioenergetic and antioxidant effects through the redox capability of its benzoquinone head group to accept and donate electrons, making it a promising therapeutic candidate for improving muscle function and physical performance.

NAD+ (β-Nicotinamide Adenine Dinucleotide) is a coenzyme composed of ribosylnicotinamide 5'-diphosphate coupled to adenosine 5'-phosphate by pyrophosphate linkage. It is found widely in nature and is involved in numerous enzymatic reactions in which it serves as an electron carrier by being alternately oxidized (NAD+) and reduced (NADH).

Pyridoxal phosphate (Vitamin B6 phosphate) is the active form of vitamin B6 and a coenzyme for many pyridoxal phosphate (PLP)-dependent enzymes. PLP is involved in numerous enzymatic transamination, decarboxylation and deamination reactions; it is necessary for the synthesis of amino acids and amino acid metabolites, and for the synthesis and/or catabolism of certain neurotransmitters, including the conversion of glutamate into gamma-aminobutyric acid (GABA) and levodopa into dopamine. PLP can be used as a dietary supplement in cases of vitamin B6 deficiency. Reduced levels of PLP in the brain can cause neurological dysfunction.

Coenzyme Q10 is a component of the electron transport chain and participates in aerobic cellular respiration, generating energy in the form of ATP. In its reduced form, it acts as an antioxidant. Coenzyme Q2 is a precursor of coenzyme Q10 that has 2, rather than 10, isoprenoid units on the ubiquinone base. It can act as an electron acceptor for bacterial Complex I. In mammalian cells, exogenous coenzyme Q2 prevents the production of reactive oxygen species associated with Complex I activity. Forms of coenzyme Q with shorter isoprenoid chains, including coenzyme Q2, induce p53-dependent apoptosis in human B-cell acute lymphoblastoid leukemia BALL-1 cells.

β-Nicotinamide adenine dinucleotide reduced dipotassium is an orally active, reduced coenzyme that functions as a donor of ADP-ribose units in ADP-ribosylation reactions and as a precursor of cyclic ADP-ribose. It also serves as a regenerative electron donor in essential cellular energy metabolism processes, including glycolysis, β-oxidation, and the tricarboxylic acid (TCA) cycle [1].

NADH disodium salt hydrate, also known as Disodium NADH hydrate, functions as an orally active reduced coenzyme. It serves as a donor of ADP-ribose units in ADP-ribosylation reactions and acts as a precursor to cyclic ADP-ribose. Additionally, it contributes to cellular energy metabolism by acting as a renewable electron donor in processes such as glycolysis, β-oxidation, and the tricarboxylic acid (TCA) cycle [1].

NADPH (reduced nicotinamide adenine dinucleotide phosphate) is a key cellular reducing coenzyme that provides reducing power during anabolic processes such as lipid and nucleic acid synthesis, and participates in the glutathione and thioredoxin systems to maintain cellular redox homeostasis. In addition, NADPH serves as an electron donor for enzymes such as NADPH oxidase, playing a crucial role in the generation of reactive oxygen species (ROS) and immune defense processes.

Myristoyl coenzyme A lithium is a myristoylated form of coenzyme A (CoA). Myristoylation, an essential process in viruses, is typically regulated by N-myristoyltransferase (NMT), which is more active in colon epithelial tumors than in normal cells. The reduced form of coenzyme A (CoA) is a key regulator of NMT activity, whereas the oxidized form does not permit NMT to promote myristoylation. Myristoyl coenzyme A potentially inhibits demyristoylation, suggesting anticancer and antiviral mechanisms.
