Question

state two sources and the functions of vitamin k​

Answer 1

Answer:

Vitamin K is an essential vitamin that supports blood clotting and healthy bones. It occurs in two forms, K-1 and K-2. Vitamin K-1 is the primary form, and it mainly comes from leafy green vegetables. Vitamin K-2 occurs in animal proteins and fermented foods.

Vitamin K-1 is primarily involved in blood coagulation. K-2 may have a more diverse range of functions in the body.

Vitamin K has antioxidant properties. It protects cellular membranes from damage due to excess free radicals, in a process known as peroxidation. Blood thinning medication, such as warfarin, can lower the antioxidative potential of vitamin K.
