| 1. | Some amino acids, such as cysteine and methionine contain sulfur.
|
| 2. | Maleimides will selectively attach to cysteine using a covalent Michael addition.
|
| 3. | First, methionine receives an adenosine group from L-cysteine.
|
| 4. | L-cysteine is a precursor to the biologic antioxidant glutathione.
|
| 5. | They are cysteine-rich globular proteins containing five disulfide bonds.
|
| 6. | A cysteine and a glutamate will interact with the aldehyde substrate.
|
| 7. | These proteins contain nine conserved cysteines which can form disulfide bridges.
|
| 8. | It is an intermediate in the synthesis of cysteine and adenosine.
|
| 9. | Cysteine is a very important molecule for a bacterium s survival.
|
| 10. | Cysteine is the crucial limiting amino acid for intracellular GSH synthesis.
