Assessment of nitric oxide level when using protein hydrolysate

The search for balanced and economically justified protein supplements of domestic production is one of the urgent tasks of feed production. The article presents the results of measuring the level of nitrite in the blood serum, which is a direct metabolite of nitric oxide. This approach allows us to more correctly assess the intensity of biochemical reactions in the body, both in normal and in pathological conditions. The stimulating effect of hydrolysate from mink carcasses on rat metabolism was studied on model systems using electron paramagnetic resonance spectroscopy. Data were obtained on a significant increase in nitrite in rat blood serum, which indicated an intensive synthesis of nitric oxide initiated by biotransformation of amino acids hydrolysate and in particular arginine.
