D-Cysteine Usage And Synthesis
| Chemical Properties | White crystalline powder |
| Uses | D-Cysteine has been used in the functionalization of QDs for applications in photocatalysis.
It can also be used in the synthesis of:
- cysteine-based chiral carbon dots (CDs)
- D-luciferin and aminoluciferin analogs
|
| Definition | ChEBI: An optically active form of cysteine having D-configuration. |
| reaction suitability | reaction type: solution phase peptide synthesis |
| Purification Methods | Purify it by recrystallisation from H2O (free from metal ions) and dry it in a vacuum. It is soluble in H2O, EtOH, Me2CO, EtOAc, AcOH, *C6H6 and CS2. Acidic solutions can be stored under N2 for a few days without deterioration. [For synthesis and spectra see Greenstein & Winitz Chemistry of the Amino Acids (J.
