succinate (succinic acid)

a 4-carbon DICARBOXYLIC ACID found in the KREBS CYCLE (see Fig. 292 ). It is formed from succinyl CoA by the ENZYME succinyl CoA synthetase. This is the only step in the cycle that directly yields a high energy bond. Succinate is subsequently oxidized to fumarate by the enzyme succinate DEHYDROGENASE.

We therefore discarded metabolites influenced by confounding variables, and we found six candidates with statistically significant differences in concentration between the control group and PAD patients: 3-hydroxybutyrate, a-ketoglutarate, glutamate, glutamine, (iso)citrate, and succinate. These candidates were useful to distinguish between PAD patients and the control group and also to discriminate between different clinical stages.
Accordingly, certain cancers are associated with genetic aberrations in TCA cycle enzymes, such as isocitrate dehydrogenase 1 (IDH1), isocitrate dehydrogenase 2 (IDH2), succinate dehydrogenase (SDH), fumarate hydratase (FH), and L-2-hydroxyglutarate dehydrogenase.
The assay was performed with 10 [micro]g of mitochondrial protein in KCl-based medium (120 mM KCl, 3 mM HEPES, 5 mM K[H.sub.2]P[O.sub.4], 3 mM MgS[O.sub.4], 1 mM EGTA, 3mg/mL BSA, pH 7.2) supplemented either with 10 mM pyruvate plus 2mM malate, 10 mM succinate, or 10 mM GP.
