Abstract[English]
Disclosed in the present invention are a physiologically acceptable salt of an arginine-arginine dipeptide and a preparation method therefor. Further disclosed is a composition containing the arginine-arginine dipeptide and the salt thereof, and arginine and a salt thereof. The method of the present invention can be used for efficient and stable production of the salt of the arginine-arginine dipeptide. The composition of the present invention does not require the separation of a small amount of arginine from the arginine-arginine dipeptide, and thus has great cost advantage and commercial potential regarding both synthesis and purification.[French]
La présente invention concerne un sel physiologiquement acceptable d'un dipeptide arginine-arginine et son procédé de préparation. L'invention concerne en outre une composition contenant le dipeptide arginine-arginine et son sel, et de l'arginine et son sel. Le procédé selon la présente invention peut être utilisé pour la production efficace et stable du sel du dipeptide arginine-arginine. La composition selon la présente invention ne nécessite pas la séparation d'une petite quantité d'arginine du dipeptide arginine-arginine, et présente ainsi une grande économie de coût et un potentiel commercial dans la synthèse et la purification.[Chinese]
