Succinic Acid | 118.09 | 1560 | R | [1] |
Succinic acid (IUPAC systematic name: butanedioic acid; historically known as spirit of amber) is a dicarboxylic acid with the formula:
HOOC–CH2–CH2–COOH
At room temperature, pure succinic acid is a solid that forms colorless, odorless crystals. It has a melting point of 185 °C and a boiling point of 235 °C. It is a diprotic acid. The anion, succinate, is a component of the citric acid cycle and is capable of donating electrons to the electron transfer chain via the following reaction:
succinate + FAD → fumarate + FADH2
This is catalysed by the enzyme succinate dehydrogenase (or complex II of the mitochondrial ETC). The complex is a 4 subunit membrane-bound lipoprotein which couples the oxidation of succinate to the reduction of ubiquinone. Intermediate electron carriers are FAD and three Fe2S2 clusters part of subunit B.
