VITAMIN K-SOURCES, PHYSIOLOGICAL ROLE, KINETICS, DEFICIENCY, THERAPEUTIC USE AND TOXICITY

RESUMO

Neama Mahmoud Taha*

As vitamin K is required for the post-transnacional alteration of seven proteins involved in this cascade, it has historically ben associated with blood coagulation. But it also helps additional 11 or 12 proteins that have distinct functions mature. These roles include controlling the calcification of connective tissues. Numerous studies have been conducted to determine whether vitamin K may be linked to the prevention of osteoporosis and cardiovascular problems because this process is pathological in arteries but physiologically necessary in bones. We regretfully cannot draw firm conclusions about such a link at this time given the state of our understanding.

The variety of vitamin K's biological activity-which is not limited to a single component but rather encompasses both synthetic congeners (K3 and K4) and natural forms of vitamin K found in plants and animals (K1 and K2). Vitamin K1, also known as phytoquinone, is present in several veggies. Menaquinones, or vitamin K2, are a class of chemicals (MK4–MK13) mostly derived from bacteria and are primarily found in fermented cheeses.

Aim: Vitamin K plays a multifaceted role in our bodies, extending beyond its well-known function in blood coagulation
