| General description【一般描述】 | Cyclohexylaminoethanesulfonic acid (CHES) is a buffering agent. Its structure contains a hydrophilic taurine (2-aminoethanesulfonic acid) moiety and a hydrophobic cyclohexyl group. CHES binds to the active site of several enzymes and inhibits substrate binding and enzymatic activity. Therefore, CHES may be used as a scaffold for new drug development for regulating enzyme activity. |
| Application【应用】 | 2-(Cyclohexylamino)ethanesulfonic acid (CHES) has been used in the preparation of dimethyl trisulfide- polysorbate 80 (DMTS-PS80) formulation. |
| Other Notes【其他说明】 | Buffer for studying pH-dependent processes in enzymology; Has a high affinity for the iodoacetate binding site of liver alcohol dehydrogenase. |
