Vitamin Vitality What are Vitamins? Vitamin K. Vitamin K, which exist in several forms, contains aromatic rings with side chains of varying length. K1 - present in green vegetables, the normal dietary source; Menaquinone Vit. K2 - synthesized by intestinal bacteria with differing lengths of side chain; Menadiol, Menadione Vit. K3 , Menadiolo Acetate — synthetic derivatives which can be metabolized to phylloquinone.

Figure 5. Structure of Phylloquinone, Menaquinone, Menadiol and Menadiol diacetate. Murray, D. Bender, K. Botham, P. Kennelly, V. Copyright by McGraw-Hill Companies. Vitamin K epoxide is reduced to the quinone by a warfarin-sensitive reductase, and the quinone is reduced to the active hydroquinone by either the same warfarin sensitive reductase or a warfarin-insensitive quinone reductase. In the presence of warfarin, vitamin K epoxide cannot be reduced, but accumulates and is excreted.

If enough vitamin K as the quinone is provided in the diet, it can be reduced to the active hydroquinone by the warfarin-insensitive enzyme, and carboxylation can continue, with stoichiometric utilization of vitamin K and excretion of the epoxide Murray et. In vitamin K deficiency, or in the presence of warfarin, an abnormal precursor of prothrombin preprothrombin containing little or no -carboxyglutamate, and incapable of chelating calcium, is released into the circulation Murray et.

Cardiovascular diseases are among the most important causes of morbidity and mortality in the world. One of the important risk factors of cardiovascular disease is hyperlipidemia especially high levels of serum cholesterol. Due to the importance of hypercholesterolemia, being a serious condition, various treatments are used to control it, regardless of the cause, most of treatments, focused on reducing the level of serum lipids. This study aims to determine various view points for hypercholesterolemia in Iranian traditional medicine. We used several Iranian traditional medicine resources and literatures; then based on these texts; a pilot study was designed to assess their effects in 10 patients with high plasma cholesterol.
