Vitamin K is usually in reference to Vitamin K1, which is also known as phylloquinone, phytomenadione, or phytonadione, and is a derivative of 1,4-naphthoquinone. A subtype exists, Vitamin K2, which is known as menaquinone.

Vitamin E is actually a group of 8 related fat-soluble compounds called tocopherols and tocotrienols, of which 4 types exist for each (alpha, beta, gamma, delta). This is why supplements for Vitamin E are often sold as a complex containing more than just one compound. The types you will see most often are gamma-Tocopherol and alpha-Tocopherol. A synthetic water-soluble form of Vitamin E is Tocofersolan.
