- Malate + ([[File:Malic_acid.jpg|left|100px|Malic aci … [[File:Malic_acid.jpg|left|100px|Malic acid]]</br>'''Malic acid''', C<sub>4</sub>H<sub>6</sub>O<sub>5</sub>, occurs under physiological conditions as the anion '''malate<sup>2-</sup>, M''', with p''K''<sub>a1</sub> = 3.40 and p''K''<sub>a2</sub> = 5.20. L-Malate is formed from fumarate in the [[TCA cycle]] in the mitochondrial matrix, where it is the substrate of [[malate dehydrogenase]] oxidized to [[oxaloacetate]]. Malate is also formed in the cytosol. It cannot permeate through the lipid bilayer of membranes and hence requires a carrier ([[dicarboxylate carrier]], [[tricarboxylate carrier]] and 2-oxoglutarate carrier). Malate alone cannot support respiration of [[Mitochondrial preparations|mt-preparations]] from most tissues, since oxaloacetate accumulates in the absence of [[pyruvate]] or [[glutamate]].</br>Malate is a [[NADH electron transfer-pathway state |type N substrate]] (N) required for the [[Fatty acid oxidation pathway control state| FAO-pathway]]. In the presence of [[Malate-anaplerotic pathway control state|anaplerotic pathways]] (''e.g.'', [[Malic enzyme|mitochondrial malic enzyme, mtME]]) the capacity of the FAO-pathway can be overestimated due to a contribution of NADH-linked respiration, F(N) (see [[SUIT-002]]).[[SUIT-002]]).)
