Mixture PurplEndurance, is a complex which guarantees of energy processes containing beta-alanine, citrulline, betaine, norvaline and ginger root. Beta-alanine and L-histidine (beta-alanyl-L-histidine) located in muscle and nerve part of carnosine (dipeptide), antioxidant, chelating and buffering braking processes glycosylation and carbonylation, allowing to extend the duration of the exercise , by slowing down the activity of catabolic enzymes. Citrulline (precursor of arginine) metabolic cycle mediates the synthesis of urea from ammonia and nitrogen excretion. It is an intermediate in a metabolic cycle urea synthesis from ammonia and glutamic acid. Polyamines synthesized regenerating liver. Betaine is involved in the conversion of homocysteine to methionine. Used in medicine in diseases of the digestive tract, neutralizes toxins and purified glyco cyanide, influences the synthesis of endogenous creatine. Norvaline, branched amino acids,not-building proteins isomer valine, arginine and inhibiting degradation intensifies its anabolic and anti-catabolic, having an impact on the increase in exercise capacity. Ginger has anti-inflammatory, anti hypotensive and anti-oxidation of LDL cholesterol. PurplEndurance blend is a component of the preparation Purple Wraath bythe company Controlled Labs, available at www.muscle-zone.pl.
