ABSTRACT – Epidemiological and experimental diets result in increased glutathione (GSH) studies suggest that dietary milk products may exert concentration in a number of tissues, and that some an inhibitory effect on the development of several of the beneficial effects of whey protein intake are types of tumors. Some recent experiments in abrogated by inhibition of GSH synthesis. Whey rodents indicate that the antitumor activity of the protein is particularly rich in substrates for GSH dairy products is in the protein fraction and more synthesis.

Whey Administration of S-(n-butyl) homocysteine protein contains substantially more cysteine than sulfoximine, which reduces splenic glutathione casein. Dietary cysteine is considered to be a rate level by half, produces a 4-5 fold drop in the limiting substrate for the synthesis of glutathione humoral immune response of whey protein diet-fed which is necessary for lymphocyte proliferation. mice.

ABSTRACT - The glutathione (GSH) antioxidant proteins also exhibit anti-carcinogenesis and system is foremost among the cellular protective anticancer activity. They do this via their effect on mechanisms. Depletion of this small molecule is a increasing GSH concentration in relevant tissues, common consequence of increased formation of and may have anti-tumor effect on low volume of reactive oxygen species during increased cellular tumor via stimulation of immunity through the activities. This phenomenon can occur in the GSH pathway. It is considered that oxygen radical lymphocytes during the development of the generation is frequently a critical step in immune response and in the muscular cells during carcinogenesis, hence the effect of GSH on free strenuous exercise. It is not surprising that so much radicals as well as carcinogen detoxification, could research has been done, and is still being done on be important in inhibiting carcinogenesis induced this small tripeptide molecule. Whey protein by a number of different mechanisms. Case reports concentrate has been shown to represent an are presented which strongly suggest an anti-tumor effective and safe cysteine donor for GSH effect of a whey protein dietary supplement in some replenishment during GSH depletion in immune urogenital cancers.
