Cysteic acid also known as 3-sulfo-l-alanine is the organic compound with the formula HO3SCH2CH(NH2)CO2H. It is often referred to as cysteate, which near neutral pH takes the form −O3SCH2CH(NH3+)CO2−.
It is an amino acid generated by oxidation of cysteine, whereby a thiol group is fully oxidized to a sulfonic acid/sulfonate group. It is further metabolized via 3-sulfolactate, which converts to pyruvate and sulfite/bisulfite. The enzyme L-cysteate sulfo-lyase catalyzes this conversion. Cysteate is not a biosynthetic precursor to taurine, which is derived from cysteine sulfinate.
