Handbook of Vitamin C Research


Book Description

The 6-carbon lactone known as ascorbic acid (vitamin C) is an important water-soluble vitamin. It is essential for preserving optimal health and it is used by the body for many purposes, including collagen biosynthesis, melanin reduction and enhanced immunity. This book addresses some important issues related to various methods which are employed to encapsulate asorbic acid. A comparation of the characteristics of ascorbic acid nano and microparticles prepared by different methods is also given. Furthermore, the biomedical significance of human vitamin C metabolism is examined, in the light of polymorphisms in xenobiotic enzymes deduced from genetic, biochemical and epidemiological results to estimate optimal nutrition. Additionally, Vitamin C exerts a protective role against some types of cancer. For that reason, this book investigates the protective effect of vitamin C. Possible pro- and antioxidant effects of vitamin C is also presented and their extrapolation on human health is discussed. Other chapters in this book include a review of the role of vitamin C in the physiology of several diseases, good dietary sources of vitamin C, a study of the effects of environmental tobacco smoke (ETS) on vitamin C status in exposed populations and the role of vitamin C in human reproduction and its effect on people who suffer from epileptic seizures.

Moon-face and Other Stories


Book Description

JACK LONDON (1876-1916), American novelist, born in San Francisco, the son of an itinerant astrologer and a spiritualist mother. He grew up in poverty, scratching a living in various legal and illegal ways -robbing the oyster beds, working in a canning factory and a jute mill, serving aged 17 as a common sailor, and taking part in the Klondike gold rush of 1897. This various experience provided the material for his works, and made him a socialist. "The son of the Wolf" (1900), the first of his collections of tales, is based upon life in the Far North, as is the book that brought him recognition, "The Call of the Wild" (1903), which tells the story of the dog Buck, who, after his master ́s death, is lured back to the primitive world to lead a wolf pack. Many other tales of struggle, travel, and adventure followed, including "The Sea-Wolf" (1904), "White Fang" (1906), "South Sea Tales" (1911), and "Jerry of the South Seas" (1917). One of London ́s most interesting novels is the semi-autobiographical "Martin Eden" (1909). He also wrote socialist treatises, autobiographical essays, and a good deal of journalism.




Beta Carotene


Book Description

ß-Carotene is an organic compound -- a red-orange pigment abundant in plants and fruits. As a carotene with ß-rings at both ends, it is the most common form of carotene. It is a precursor (inactive form) of vitamin A. ß-carotene is abundant in Vietnam gac, crude palm oil, yellow and orange fruits, such as mangoes and papayas, orange root vegetables such as carrots and yams and in green leafy vegetables such as spinach, kale, sweet potato leaves, and sweet gourd leaves. Vietnam gac and crude palm oil have by far the highest content of ß-carotene of any known fruit or vegetable, 10 times higher than carrots for example. The most common side effect of excessive ß-carotene consumption is carotenodermia, a harmless condition that presents as a conspicuous orange skin tint arising from deposition of the carotenoid in the outermost layer of the epidermis. High doses of ß-carotene have been associated with increased rate of lung cancer among those who smoke. This new book gathers the latest research from around the globe in this field.




The School Promoters


Book Description

We tend to think of contemporary concern for reform in education as unprecedented in its intensity and scope. But as this book about mid-nineteenth century educational ideology shows, the urge to improve society through its schools has been with us a long time. The author examines the attitudes that shaped the Ontario public school system during its formative years, when Upper Canadians first explored and the provincial government finally adopted the principle of compulsory mass schooling under the auspices and control of the state.







Diet Quality of Americans
