Discussion and Conclusions Many diseases are due to an imbalance between oxidant production rate (free radicals or reactive species), and the activity of cellular antioxidant systems

Carter also rated mixability as a 5: The collagen dissolved well within the 60-second window and did not leave any chalky or grainy consistency behind
However, the traditional view that NADPH is required strictly for the glutathione peroxidase and catalase systems need to be revised with new insights in the form of another major player in RBC antioxidant defense, peroxiredoxin 2 (Prdx2)
actioneaza si la nivel cerebral datorita capacitatii de a traversa bariera hemato-encefalica: glutationul redus este principalul transportator al gruparilor SH (sulfhidril) libere care au o mare capacitate de a neutraliza radicalii liberi prin cedarea unei perechi de electroni reducerea actiunii enzimelor proinflamatoare asupra celulelor cu membrane bogate in acizi grasi polinesaturati (de ex.: celulele imunitare, spermatozoizii, hepatocitele, neuronii etc.) participa la faza I si II de detoxifiere hepatica: reducerea absorbtiei si favorizarea eliminarii din organism a substantelor nocive endogene (hormoni in exces, enzime proinflamatoare, melanina s.a.) si a xenobioticelor (metale grele, fum de tigara, alcool, pesticide, fungicide, erbicide, coloranti si aditivi alimentari toxici [de ex.: formaldehida], droguri, microorganisme nocive, detergenti, grasimi vegetale hidrogenate, nitrozamine, metilglioxal s.a.) stimularea secretiei de gama-interferon, interleukina IL-2, limfocite T citotoxice, NK, activarea macrofagelor si granulocitelor cu rol in reglarea diviziunii celulare normale si reducerea actiunii agentilor agresori cu potential de modificare a ADN-ului si ARN-ului celular mentinerea nivelului de glutation in stari cu deficit de sinteza cauzat de microorganisme nocive, droguri, alcool, anticonceptionale, amoniac, metale grele, pesticide, hormoni, consum redus de proteine, diviziune celulara anormala, chimio si radioterapie, interventii chirurgicale, arsuri, inaintarea in varsta etc
