- Ketone bodies are strong organic acids that fully dissociate in blood. (medscape.com)
Isocitric Acid1
- Hint: This is not asking for the intermediate molecules (i.e. isocitric acid, succinic acid, etc. (australiaessaywriting.com)
Ratio of hydroxybutyric acid1
- The resulting increase in the NADH/NAD + ratio inhibits hepatic gluconeogenesis and elevates the ratio of hydroxybutyric acid to acetoacetic acid. (medscape.com)
Inner membrane1
- Countering NADH production, calcium action on the mitochondrial permeability transition pores increases inner membrane permeability thereby reducing proton potential, causing the matrix to swell and ultimately releasing cytochrome c (an initiator of apoptosis). (benbest.com)
Dehydrogenase6
- Much like pyruvate dehydrogenase complex (PDC), this enzyme forms a complex composed of three components: Three classes of these multienzyme complexes have been characterized: one specific for pyruvate, a second specific for 2-oxoglutarate, and a third specific for branched-chain α-keto acids. (wikipedia.org)
- The oxoglutarate dehydrogenase complex has the same subunit structure and thus uses the same coenzymes as the pyruvate dehydrogenase complex and the branched-chain alpha-keto acid dehydrogenase complex (TTP, CoA, lipoate, FAD and NAD). (wikipedia.org)
- Increased Oxoglutarate dehydrogenase activation levels serve to increase the concentrations of NADH relative to NAD+. (wikipedia.org)
- It is believed that the temporary inhibition of mitochondrial function stems from the reversible glutathionylation of the E2-lipoac acid domain of Oxoglutarate dehydrogenase. (wikipedia.org)
- During this reaction, pyruvic acid is also oxidized and NAD + is reduced to NADH by pyruvate dehydrogenase complex (PDHC). (learninsta.com)
- Acetaldehyde is metabolized further to acetic acid by aldehyde dehydrogenase. (medscape.com)
Mitochondrial1
- Fatty acids, which are often found in chains as CoA-esters, are first transported across the outer mitochondrial membrane by palmitoyl transferase I, resulting in translocation to the intermembrane space and transformation into an acyl-carnitine form. (biomedcentral.com)
Reduction1
- Then, the NAD+ to NADH and H+ reduction. (brighthub.com)
