Antioxidants and performance Introduction Free radicals are reactive chemical species that can cause oxidation injury to the living beings by attacking the macromolecules like lipids, carbohydrates, proteins and nucleic acids. However, antioxidants protect the cells from damage caused by these unstable molecules what are antioxidants? Antioxidant is a molecule that inhibits the oxidation of other molecules. Oxidation is a chemical reaction involving the loss of electrons or an increase in oxidation state. Oxidation reactions can produce free radicals.
Determination of antioxidant activity Scavenging DPPH radicals DPPH (2,2-diphenyl-1-picryl-hydrazyl-hydrate) radical is used free radical method is an in antioxidant assay forwas used to evaluate measured the free radical scavenging activity of the lichen extract . Two millilitreers of 0 .05 mg/mL methanol solution of DPPH radical in the concentration of (0 .05 mg/mL) and 1 mL of the lichen extract (1 mg/mL) were placed in cuvettes. The mixture is storewas stored stand at room temperature for 30 min. Then, the absorbance was measured at 517 nm in a spectrophotometer (Jenway, UK). Ascorbic acid was used as a positive control.
Ascorbic acid with the chemical formula C6H8O6 is comprised of L-dehydroascorbic acid and L-ascorbic acids. Ascorbic acid is most commonly known as Vitamin C, which many know are most commonly found in citrus fruits and some vegetables, eg; oranges, limes, lemons, bell peppers, etc.Vitamin C can be easily oxidized, when the ascorbic acid reacts to form dehydroascorbic acid. This is when two hydrogen atoms are lost, forming two ketone groups. Vitamin C is also a biological compound that is actively involved in the synthesis of collagen which is responsible for the structural protein in the hair, nail and skin growth. The vitamin C also has an active role in the detoxification of the by-products involved in the respiration process. During respiration,
Its leaves contain a mixture of azadirachtin, salannin, melantriol and nimbin which all have medicinal properties. Azadirachtin is the primary active ingredient with antifungal, antibacterial, antiviral, antihelmintic and even anti-diabetic properties (Banerjee, Pooja S,2012) Ginger is a flowering plant whose ginger root (rhizome) is widely used as a spice and natural medicine. It has antibacterial, anti-oxidant, antiviral properties and has been used to treat colds, migraines, hypertension etc ( ). The oleoresin from the roots contains “bioactive components” which provide these properties.
Herbal products have been used for treatments since ancient times, before the exploration of synthetic industrial drugs. Since herbs are natural, most of the consumers believes herbal products are completely safe and the product use continuously increased and is reported 10-19% growth in United States. In U.S.A any botanical product affects the structure and functions of the body belongs to either a drug or dietary supplement and FDA regulates the dietary supplement. The author of this paper selected St. John’s wort ,as the herbal supplement for this assignment of patient educational flyer. Product Description: St. John’s wort (SJW) is a yellow flowering plant, grows in the wild used for health purpose for long time .The
Natural product and its derivatives have been recognized as therapeutic agents (Lahlou, 2013). Due to adverse effects from modern medicine and synthetic product, there is increase interest on discovering alternative natural product as therapeutic agent and become alternative for modern medicine since natural product has lesser adverse
The History and Science of Healing With Essential Oils Did you know that at least 30% of prescription drugs in the United States are based on naturally occurring compounds from plants? Each year, millions of dollars are spent searching for new, undiscovered, curative elements in the bark, roots, flowers, seeds and foliage of plants from every corner of the Earth. As the most powerful part of the plant, essential oils and plant extracts have been mankind 's first medicine. History has shown and science supports that these can be used medicinally to kill bacteria and viruses.
2) Free Radicals: an injury by free radicals such as the reactive oxygen species, also known as oxidative stress (Huether & McCance, 2012, p. 66). This is an uncharged atom that makes the molecule unstable. In order to become stabilized, it needs to either get an electron or give up its electron. By doing this, it forms chemical bonds with protein,
GREEN PEAS have a bunch of antioxidants and anti-inflammatory properties that play a primary role in preventing cancers. Green peas high amount of health-protective polyphenol called coumestrol acts as a defending agent against cancers. Excessive inflammation and oxidative stress are the risk factors for the abnormal cell growth. The risk factor for stomach and gastric tumors increases in persons whose intake of antioxidant, polyphenols, and anti-inflammatory nutrients are low.
Toxins are present in everyday life in a variety of places. Ethylene glycol, commonly found in antifreeze and other household products. Ethylene glycol can be toxic to humans, as well as pets. With antifreeze founds in many households, it is common for pets to find and ingest this toxin. Commonly found in garages where antifreeze is kept, the sweet tasting liquid is often was entices pets to drink it up. Even in the smallest amounts, ethylene glycol has been proven toxic. Dogs often lap it up in the garage if it has spilled on the floor and cats can come into contact with it simply by stepping in it and then licking their paws, therefore ingesting it.
Several studies have shown that biologically active components of some fruits and vegetables may have a promising protective effect against cancer cell formation and proliferation. The mechanism of action has yet to be fully determined, but it has been suggested that alterations in epigenetic mechanisms may have a vital role in this phenomenon . The emergence of epigenetics and the correlation that has been found between factors such as diet and lifestyle with various cancers emphasizes that proper nutrition is critical during all phases of life. Elucidating the influence of nutritional involvement in epigenetic mechanisms may be instrumental in predicting inter-individual differences in regards to susceptibility to cancer and providing uses of natural compounds against cancer. The purpose of this review is to provide an overview of current research on cancer epigenetics and nutrition and to elaborate the potential of non-coding RNAs (ncRNAs) and dietary factors in cancer prevention and
Propylene Glycol Propylene Glycol is found in antifreeze, it is a humectant which means it is hydrating but is also a skin irritant. It is widely found in skin care products such as body washes, deodorants, shampoo, conditioner and liquid for e-cigarettes. This is because it is cheaper for companies to add this to their products rather than using botanical ingredients. By adding Propylene Glycol it prevents the product from spoiling in hot and cold temperature and helps products to sink into the skin. Although Propylene Glycolic can work into the blood stream.
A comparative research study has give evident that cocoa have higher antioxidant activity than black tea, green tea, and red wine. iii. Antioxidants help to neutralize the oxygen-based free radicals that are present in the body. iv. Free radicals are associated with human disease, including cancer, atherosclerosis, Alzheimer 's disease, Parkinson 's disease and many others.
