succinate; succinic acid

Biochemistry

• succinate is an intermediate in the citric acid cycle
• it is formed by hydrolysis of succinyl CoA via succinyl-CoA synthetase
  • enzyme: succinyl-CoA synthetase
  • substrates: succinyl-CoA + GDP + H2PO4-
  • products: succinate + coenzyme-A + GTP
• succinate is metabolized to form fumarate via succinate dehydrogenase in a reaction that feeds electrons into the electron transport chain (complex II) through flavin adenine dinucleotide (FADH2)
  • enzyme: succinate dehydrogenase
  • substrates: succinate + flavin adenine dinucleotide
  • products: fumarate + FADH2
