Significant enhancement in antioxidant and antimicrobial activity of tragacanth gum through chemical modification using amino acids.

Herein, glutamic acid, lysine, arginine and glycine grafted tragacanth gum (TG) were synthesized and designated as TG-Glu, TG-Lys, TG-Arg, and TG-Gly, respectively. The corresponding degrees of substitution (DS) were 0.212, 0.
