Vitamin C
Vitamin C, also known as ascorbic acid and -ascorbic acid, is a vitamin found in food and used as a dietary supplement. The disease scurvy is prevented and treated with vitamin C-containing foods or dietary supplements. Evidence does not support use in the general population for the prevention of the common cold. There is, however, some evidence that regular use may shorten the length of colds. It is unclear if supplementation affects the risk of cancer, cardiovascular disease, or dementia. It may be taken by mouth or by injection. Vitamin C is generally well tolerated. Large doses may cause gastrointestinal discomfort, headache, trouble sleeping, and flushing of the skin.
Ascorbic acid (molecular aspects)
Ascorbic acid is a naturally occurring organic compound with antioxidant properties. It is a white solid, but impure samples can appear yellowish. It dissolves well in water to give mildly acidic solutions. Ascorbic acid is one form ("vitamer") of vitamin C. It was originally called -hexuronic acid, but, when it was found to have vitamin C activity in animals ("vitamin C" being defined as a vitamin activity, not then a specific substance), the suggestion was made to rename it. The new name, ascorbic acid, is derived from "a-" (meaning "no") and "scorbutus" (scurvy), the disease caused by a deficiency of vitamin C. Because it is derived from glucose, many animals are able to produce it, but humans require it as part of their nutrition.
Scurvy
Scurvy is a disease resulting from a lack of vitamin C. Early symptoms include weakness, feeling tired, and sore arms and legs. Without treatment, decreased red blood cells, gum disease, changes to hair, and bleeding from the skin may occur. As scurvy worsens there can be poor wound healing, personality changes, and finally death from infection or bleeding. Typically, scurvy is caused by a lack of vitamin C in the diet. It takes at least a month of little to no vitamin C before symptoms occur. In modern times, it occurs most commonly in people with mental disorders, unusual eating habits, alcoholism, and old people who live alone.
Cat food
Cat food is food for consumption by cats. Cats have specific requirements for their dietary nutrients. Certain nutrients, including many vitamins and amino acids, are degraded by the temperatures, pressures and chemical treatments used during manufacture, and hence must be added after manufacture to avoid nutritional deficiency. The amino acid taurine, for example, which is found in meat, is degraded during processing, so synthetic taurine is normally added afterwards. Long-term taurine deficiency may result in retinal degeneration, loss of vision, and cardiac arrest. The idea of preparing specialized food for cats came later than for dogs (see dog biscuits and dog food).
Antioxidant
An antioxidant is a molecule that inhibits the oxidation of other molecules. Oxidation is a chemical reaction that can produce free radicals, leading to chain reactions that may damage cells. Antioxidants such as thiols or ascorbic acid (vitamin C) terminate these chain reactions. The term "antioxidant" is mainly used for two different groups of substances: industrial chemicals which are added to products to prevent oxidation, and natural chemicals found in foods and body tissue which are said to have beneficial health effects. To balance the oxidative state, plants and animals maintain complex systems of overlapping antioxidants, such as glutathione and enzymes (e.g., catalase and superoxide dismutase) produced internally or the dietary antioxidants: vitamin A, vitamin C, and vitamin E.  Antioxidant dietary supplements do not improve health nor are they effective in preventing diseases as shown by randomized clinical trials including supplements of beta-carotene, vitamin A, and vitamin E singly or in different combinations having no effect on mortality rate or cancer risk.
Vitamin C megadosage
Vitamin C megadosage is a term describing the consumption or injection of vitamin C (ascorbate) in doses comparable to the amounts produced by the livers of most other mammals. Such dosages correspond to amounts well beyond the current Recommended Dietary Allowance of 90 mg/day, and often well beyond the Tolerable upper intake level of 2000 mg/day. Oral dosages are usually divided and consumed in portions over the day. Injections of hundreds of grams per day are advocated by some physicians for the treatment of certain conditions, poisonings, or recovery from trauma. People who practice vitamin C megadosage may consume many vitamin C pills throughout each day or dissolve pure vitamin C crystals in water or juice and drink it throughout the day.
L-gulonolactone oxidase
-gulonolactone oxidase (EC 1.1.3.8) is an enzyme that produces vitamin C, but is non-functional in Haplorrhini (including humans), in some bats, and in guinea pigs. It catalyzes the reaction of -gulono-1,4-lactone with oxygen to -xylo-hex-3-gulonolactone and hydrogen peroxide. It uses FAD as a cofactor. The -xylo-hex-3-gulonolactone (2-keto-gulono-gamma-lactone) is able to convert to hexuronic acid (ascorbic acid) spontaneously, without enzymatic action. The non-functional gulonolactone oxidase pseudogene (GULOP) was mapped to human chromosome 8p21 that corresponds to an evolutionarily conserved segment on either porcine chromosome 4 (SSC4) or 14 (SSC14).

Vitamin
A vitamin is an organic compound and an essential nutrient that an organism requires in limited amounts. An organic chemical compound (or related set of compounds) is called a vitamin when the organism cannot synthesize the compound in sufficient quantities, and it must be obtained through the diet; thus, the term "vitamin" is conditional upon the circumstances and the particular organism. For example, ascorbic acid (one form of vitamin C) is a vitamin for humans, but not for most other animals. Vitamin D is essential only for people who do not have adequate skin exposure to sunlight, as ultraviolet light promotes synthesis in skin cells.
Linus Pauling
Linus Carl Pauling (; February 28, 1901 – August 19, 1994) was an American chemist, biochemist, peace activist, author, and educator. He published more than 1,200 papers and books, of which about 850 dealt with scientific topics. "New Scientist" called him one of the 20 greatest scientists of all time, and as of 2000, he was rated the 16th most important scientist in history. Pauling was one of the founders of the fields of quantum chemistry and molecular biology. His contributions to the theory of the chemical bond include the concept of orbital hybridisation and the first accurate scale of electronegativities of the elements.
Nutrition
Nutrition is the science that interprets the interaction of nutrients and other substances in food in relation to maintenance, growth, reproduction, health and disease of an organism. It includes food intake, absorption, assimilation, biosynthesis, catabolism, and excretion. The diet of an organism is what it eats, which is largely determined by the availability and palatability of foods. For humans, a healthy diet includes preparation of food and storage methods that preserve nutrients from oxidation, heat or leaching, and that reduce risk of foodborne illness. In humans, an unhealthy diet can cause deficiency-related diseases such as blindness, anemia, scurvy, preterm birth, stillbirth and cretinism, or nutrient excess health-threatening conditions such as obesity and metabolic syndrome; and such common chronic systemic diseases as cardiovascular disease, diabetes, and osteoporosis.
Vitamin C (singer)
Colleen Ann Fitzpatrick (born July 20, 1972), better known by her stage name Vitamin C, is an American pop music singer, songwriter, record producer, dancer, and actress. She began her career as an Ivory soap baby and child actress, appearing in John Waters' film "Hairspray" (1988), and continued to appear in minor roles in films before starting the alternative rock band Eve's Plum in 1991. In 1999, Fitzpatrick embarked on a solo career under the name Vitamin C, releasing her eponymous debut album "Vitamin C" (1999), which was certified as Gold and later Platinum by the RIAA. Singles from the record include "Graduation (Friends Forever)" and her most successful hit, the Top 20 Gold certified "Smile".

yes! oranges are high in vitamin C and some evidence show that regular use of vitamin C may shorten the length of colds
Evidence does not support use in the general population for the prevention of the common cold.

Vitamin C and the Common Cold (book)
Vitamin C and the Common Cold is a popular book by Linus Pauling, first published in 1970, on vitamin C, its interactions with common cold and the role of vitamin C megadosage in human health. The book promoted the idea that taking large amounts of vitamin C could reduce the duration and severity of the common cold. A Nobel Prize-winning chemist and activist, Pauling promoted a view of vitamin C that is strongly at odds with most of the scientific community, which found little evidence for the alleged health benefits of greatly increased vitamin C intake. The book went through multiple editions, and a revised version that discussed the flu and other diseases, retitled Vitamin C, the Common Cold & the Flu, came out in 1976.
Vitamin C and the common cold
The common cold, or simply cold, is a viral infectious disease of the upper respiratory tract. The cold is indeed common, and is a significant cause for absences from work and school. Even before the discovery of vitamin C, folklore had it that certain fruits were effective in both preventing and treating the cold. After scientific identification of vitamin C in the early part of the 20th century, research began into the possible effects of the vitamin against the common cold. Vitamin C has not decreased the frequency of colds in the general population, but it has halved the frequency of colds in people under heavy short-term physical stress.
Megavitamin therapy
Megavitamin therapy is the use of large doses of vitamins, often many times greater than the recommended dietary allowance (RDA) in the attempt to prevent or treat diseases. Megavitamin therapy is typically used in alternative medicine by practitioners who call their approach orthomolecular medicine, but also used in mainstream medicine for rare genetic conditions that respond to megadoses of vitamins. Nutrients may be useful in preventing and treating some illnesses, but the conclusions of medical research are that the broad claims of disease treatment by advocates of megavitamin therapy are unsubstantiated by the available evidence.
