Product Application of L-Arginine L-glutamate CAS#4320-30-3
L-Arginine L-glutamate functions as a flavor enhancer, primarily applied to improve the sensory quality of green tea at a typical addition level of 1%–2%. While L-glutamic acid and L-arginine are not defined as essential amino acids, they are regarded as conditionally essential for infants and young children, given their insufficient endogenous synthesis capacity of L-arginine. Additionally, L-arginine exerts positive effects on retinal tissues, rendering this compound suitable for pharmaceutical applications.
