“…Glycine was detected in all other fish species except L. pangusia, N. hexagonolepis and T. putitora (Table-1). Glycine helps in metabolic regulation, prevents tissue injury, increases antiantioxidant activity, promotes protein synthesis and wound healing, and improves immunity and treatment of metabolic disorders in obesity, diabetes, cardiovascular disease, ischemiareperfusion injuries, cancer, and various inflammatory diseases [2,3,9]. It is seen from Table-1 that 11 different amino acids were detected in all the 10 fish species and these were phosphoserine (2.82 % in F-10 to 13.22 % in F-5), aspartic acid (0.55 % in F-7 to 6.43 % in F-1), glutamic acid (1.42 % in F-8 to 5.15 % in F-9), amino adipic acid (0.68 % in F-2 to 6.25 % in F-7), serine (1.97 % in F-7 to 13.63 % in F-3), taurine (1.96 % in F-1 to 18.08 % in F-3), 1-methyl histidine (1.57 % in F-1 to 11.24 % in F-9), ornithine (2.85 % in F-9 to 9.71 % in F-7), threonine (0.41 % in F-4 to 7.34 % in F-7), valine (0.82 % in F-3 to 10.35 % in F-4), and lysine (0.55 % in F-8 to 10.52 % in F-3).…”
