Preparation of L(+)-Arginine: L(+)-Arginine (CAS NO.74-79-3) is synthesized from citrulline by the sequential action of the cytosolic enzymes argininosuccinate synthetase (ASS) and argininosuccinate lyase (ASL).
Uses of L(+)-Arginine: L(+)-Arginine plays an important role in cell division, the healing of wounds, removing ammonia from the body, immune function, and the release of hormones. It is also used as precursor for the synthesis of nitric oxide (NO). And it can reduces healing time of injuries (particularly bone), quickens repair time of damaged tissue and helps decrease blood pressure.
When you are using this chemical, please be cautious about it as the following:
1. Avoid contact with skin and eyes;
2. Wear suitable protective clothing;
3. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice;
You can still convert the following datas into molecular structure:
