Vitamin K Solubility and Properties

The video explains that Vitamin K is fat-soluble due to its nonpolar molecular structure. It compares Vitamin K with triglycerides, highlighting their similar nonpolar characteristics, which allow Vitamin K to dissolve in fat. In contrast, water is a polar molecule, and polar substances dissolve in water. Therefore, Vitamin K does not dissolve in water. The video concludes by reaffirming that Vitamin K is fat-soluble.
