Kyselina cysteová (3-sulfoalanín) je organická zlúčenina, ktorý vzniká v metabolizme cysteínu.[1] Jej konjugovanou zásadou je cysteát.

U mikrorias je cysteát biosyntetickým prekurzorom taurínu.[2] U ľudí sa väčšina taurínu syntetizuje z cysteínsulfinátu.[3]

Metabolizmus

Cysteát vzniká oxidáciou cysteínu, pričom dochádza k oxidácii tiolovej skupiny na sulfónovú kyselinu. Reakciu katalyzuje cysteínlyáza, pričom dochádza k štiepeniu sulfánu a jeho náhrade za siričitan:[4][5]

cysteín + H2SO3 → cysteát + H2S

Cysteát sa potom rozkladá na pyruvát, siričitan a amoniak pôsobením cysteátsulfolyázy:[6]

cysteát + H2O → pyruvát + SO32- + NH4+
