Glutathione Essays

Evaluate the role of Glutathione in combating oxidative stress The balance between the production of reactive oxygen species (ROS), also known as free radicals, and antioxidant defences is defined as oxidative stress1. When cellular antioxidant defences are insufficient to keep ROS below a toxic threshold, oxidative stress causes damage to cells. Oxidative stress can be caused by an increase in free radicals and other ROS, or by decrease in antioxidants such as glutathione (GSH). GSH is a naturally

Glutathione is a combination of three amino acids or simple building blocks of protein - glycine, glutamic acid, and cysteine. It is naturally produced by the body, similar to alpha lipoic acid and coenzyme Q10, and can be found in every cell. Glutathione functions as a vital antioxidant in the body. One of the most well-known glutathione benefits is that it is very useful in fighting free radicals – molecules that could harm the cells in the body. Glutathione is important in a lot of chemical reactions

In both ‘Digging’ and ‘Follower’, Heaney creates a tone of respect and admiration for his father and grandfather that permeate all aspects of the poems. He portrays them as being strong, skilful and dedicated; this is achieved through the use of vivid descriptions, structure and careful placement of words with connotations. In ‘Follower’, Heaney portrays his father as skilled and knowledgeable. Throughout out the poem, Heaney uses specialized terms to describe his father’s job, such as ‘shafts’

xenobiotic-CoA thioester intermediate that will link the activated acyl group to the amino group of the acceptor amino acid with regeneration of CoASH.101 Glutathione conjugation involves conjugation of the tripeptide glutathione with a xenobiotic that is enzymatically catalyzed by glutathione transferases. The detoxification pathway of xenobiotics via glutathione is discussed in

enzymes, superoxide dismutase, glutathione reductase, glutathione s-transferase, and glutathione peroxidase and actual glutathione levels in the body substantially. This can reverse disrupted oxidative phosphorylation (OXPHOS) in the mitochondria. Disruption of ATP causes cells to revert to enzymatic ATP production through aerobic glycolysis in the cytoplasm, a process that can convert normal cells into cancer cells. Therefore, it’s an increase in enzymes and glutathione that helps to reverse the disrupted

These free radicals interacts with fatty acids of lung cell membrane and increase lipid peroxidation and DNA fragmentation. Moreover, they suppress antioxidant enzymes including catalase, superoxide dismutase, glutathione (GSH), oxidized glutathione (GSSG), glutathione reductase and glutathione peroxide (1,2,4).

3. Results The preliminary phytochemical screening of the roots of P. zeylanica showed the presence of sugars, steroids, flavonoids, alkaloids, terpenoids, quinones, phenols, and tannins (Table 11). Alkaloid was seen in ethyl acetate and methanol extracts while terpenoid was noticed only in the chloroform extract. Flavonoid was present only in the methanol extract. HPTLC fingerprinting of ethanol extract of P. zeylanica yield the following results. The Rf values and colour of the spots were recorded

Chemical reactivity measurement of test chemicals towards nucleophiles is getting more attention as an alternative to animal method in testing for potency of skin sensitizers. In view of this, alternative methods are expected to be highly reproducible. To achieve this, there is need for proper investigation of appropriate method of analysis. Depletion of protein nucleophiles and formation of covalent adducts between skin sensitizers and dermal proteins are very important processes in skin sensitization

rich source of folate, which according to experts may reduce the risk of pancreatic cancer, colon cancer and oesophageal cancer. The presence of vitamin C and beta-carotene also aids in cancer protection. Other than folate, asparagus also contains glutathione. The detoxifying property of this compound is helpful in breaking down carcinogens. Asparagus also contains a carbohydrate called inulin. Inulin is not digested in the upper intestinal tract and helps in the better absorption of nutrients in the

2.9. Estimation of Hydrogen peroxide (H2O2) 10 213 The concentration of H2O2 was determined by the method of Okuda et al (38). Fresh leaf 214 sample (0.5 g) was grounded in ice-cold 200 mM HClO4 and was then centrifuged at 215 1200 g for 10 min followed by neutralization of HClO4 of the supernatant with 4M KOH. 216 The insoluble KClO4 was eliminated by further centrifugation at 500g for 3 min. In a 217 total volume of 1.5 mL, the reaction mixture contained 1 mL of the eluate, 400 mL of 218 12.5 mM

important to humans and most other animals and act as anti-aging, repairing cells, improving human immunity and preventing carcinogenesis but toxicity occurs when taken in large quantity. It is also a basic component of various enzymes such as glutathione peroxidase (GSH-Px) and thioredoxin reductase (TR), which involve in the antioxidant protection of cells (Rotruck et al., 1973; Birringer et al., 2002). Deficiency

Selenium - The Element In 1817, Jöns Jacob Berzelius found out an unknown substance with properties similar to that of tellurium and named it as Selenium, from the Greek word Selene, which denotes goddess of the moon1. Selenium is one of the rarest elements that are found naturally in the earth’s crust. It occupies group 16 (chalcogens) of the periodic table of elements with atomic number 34 and symbol Se. Selenium exists in multiple allotropic forms but only three are recognised. The most stable

1. Introduction Liver disease represents a considerable public health burden that involves several etiologies overlapping symptoms (El-Serag & Rudolph, 2007). Since the seventies, the experimental model of carbon tetrachloride (CCl4) hepatotoxicity have been closely studied using in vivo models of acute and chronic liver injury. This process has been used comprehensively to examine the pathogenesis of liver injury such as centrilobular steatosis, inflammation, apoptosis and necrosis. CCl4 deteriorates

2-chloro-4-ethyl-amino-6-amino-1,3,5-triazine (ETHYL) and 2-chloro-4-amino-6-isopropylamino-1,3,5-triazine (ISO). These products are then metabolized again via cytochrome p450 to the major metabolite, diaminochlorotriazine (DACT). These metabolites can then undergo glutathione S-transferase (GST) mediated GSH conjugation to form unreactive non-chlorinated metabolites, that can then be excreted
