Succinic acid (HO₂CCH₂CH₂CO₂H) is an intermediate in the Kreb's cycle used to "burn" carbohydrates, proteins and lipids. The formula for succinic acid can be abbreviated as H₂Sc.
H₂Sc(aq) + H₂O(l) $Succinic acid (HO2CCH2CH2CO2H) is an intermediate in the Kreb's cycle used to burn carbohydrates, proteins and lipids. The formula for succinic acid can be abbreviated as H2Sc.
