Abstract
Vitamin K occurs in dietary supply in two major forms: phylloquinone (vitamin K1) and menaquinones (collectively referred as vitamin K2). Phylloquinone is derived from plants. There are at least 10 forms of menaquinones varying in chain length and they are produced by bacteria except menaquinone-4. Menaquinone-4 is formed from phylloquinone or other menaquinone forms. Phylloquinone is considered to be the major contributor and menaquinones are thought to contribute less to vitamin K intake in Western diets. However, less is known about the content of menaquinones than phylloquinones in foods. Vitamin K is known to function as an enzymatic cofactor in the gamma-carboxylation of vitamin K dependent proteins (VKDPs). Hepatic VKDPs are involved in coagulation. Extrahepatic VKDPs have a role e.g. in bone health and vascular calcification. However, the amount of vitamin K needed for optimal functioning of the different VKDPs is not known.
期刊介绍：
Food & Nutrition Research is a peer-reviewed journal that presents the latest scientific research in various fields focusing on human nutrition. The journal publishes both quantitative and qualitative research papers.
Through an Open Access publishing model, Food & Nutrition Research opens an important forum for researchers from academic and private arenas to exchange the latest results from research on human nutrition in a broad sense, both original papers and reviews, including:
* Associations and effects of foods and nutrients on health
* Dietary patterns and health
* Molecular nutrition
* Health claims on foods
* Nutrition and cognitive functions
* Nutritional effects of food composition and processing
* Nutrition in developing countries
* Animal and in vitro models with clear relevance for human nutrition
* Nutrition and the Environment
* Food and Nutrition Education
* Nutrition and Economics
Research papers on food chemistry (focus on chemical composition and analysis of foods) are generally not considered eligible, unless the results have a clear impact on human nutrition.
The journal focuses on the different aspects of nutrition for people involved in nutrition research such as Dentists, Dieticians, Medical doctors, Nutritionists, Teachers, Journalists and Manufacturers in the food and pharmaceutical industries.
