  Hydrogen sulfide plays a crucial role in human and animal physiology.Its ubiquity and versatile properties have recently caught the attention of plant physiologists and biochemists.L-CD and D-CD, were identified as being mainly responsible for the degradation of cysteine in order to generate H2S.
