Concentration of free amino acids and dipeptides in porcine skeletal muscles with different oxidative patterns

Free amino acids and natural dipeptides, have been analyzed in pork muscles having different metabolic type ( masseter, trapezius, semimembranosus and longissimus dorsi). Carnosine and anserine showed significantly higher ( p < 0.05) concentrations with the glycolytic activity of the muscle while...

Description
Summary:Free amino acids and natural dipeptides, have been analyzed in pork muscles having different metabolic type ( masseter, trapezius, semimembranosus and longissimus dorsi). Carnosine and anserine showed significantly higher ( p < 0.05) concentrations with the glycolytic activity of the muscle while taurine and glutamine were significantly higher in the oxidative muscles. Non-essential free amino acids also showed significant ( p < 0.05) increased content in the oxidative muscles.
