Hello,

I am doing a research on sulfonates but i can't seem to find any valuable resources online , after many vain attempts i have joined the Chemical Forum in hope that i will get some elucidations on the subject .
The research includes a definition , synthesis (how to synthesize Sulfonates? ) and applications (where are they used? ) , any other informations would be equally helpful.

I would be grateful for any contribution to the research or a direction towards useful resources.

Thank you

Cysteine sulfonate (or its conjugate acid, cysteine sulfonic acid) is produced in some instances when a protein is being degraded to determine which amino acids are present (amino acid analysis).  Cysteine is one of the twenty amino acids commonly found in proteins.  IIRC performic acid is used to produce cysteine sulfonate.  Try PubMed for more information on sulfonates of biological interest.
