However, as the activities of cysteine dioxygenase (CD) and cysteine sulfinic acid decarboxylase (CSAD), which are enzymes involved in taurine synthesis, are too low to trigger taurine biosynthesis in the human body (Rigo and Senterre, 1977; Sturman and Hayes, 1980), taurine must be supplied by outside sources.
The major pathway is Cys oxidization into cysteine sulfinic acid, decarbonization into hypotaurine, and finally oxidization into taurine.
The process comprising the steps of: (a) forming a monomer mixture comprising at least one monomer capable of forming a superabsorbent polymer, a crosslinking agent and an initiator system comprising a sulfinic acid derivative having a structure.
In this work, they present 13 review articles describing various aspects of this emerging field, including asymmetric synthesis of chiral sulfoxides, asymmetric synthesis of optically active sulfinic acid esters, asymmetric transformations mediated by sulfinyl groups, synthesis and applications of chiral dithiocetal derivatives, synthesis and use of chiral sulfur ylides, synthesis and use of chiral sulfoximines, synthesis and use of chiral sulfinamides, asymmetric catalysis using sulfoxides as ligands, sulfones in asymmetric catalysis, and computational studies on asymmetric reactions with sulfur reagents.
Test results concluded that drier Piedmont hair tresses promote photochemical reaction at the disulfide site, creating thiosulfonate end products, while more moist hair oxidizes sulfur into what is thought to be sulfinic acid.

In the meantime, pyridoxal-5-phosphate (vitamin B6 or pyridoxin) is needed as a coenzyme for the activities of various enzymes necessary for the conversion of cystine into taurine such as cysteine dioxygenase (CD), cysteine sulfinic acid decarboxylase (CSAD), etc.
