High Quality Vitamin K3 for Feed Additive

Product Description

MenadioneIt is sometimes called vitamin K3, although derivatives of naphthoquinone are not naturally occurring chemicals and therefore do not qualify as vitamins, and without the side chain in the 2-position (which, as the methyl group is retained in vitamine K, in the structural formula of menadione is the unsubstituted 3-position!) they cannot exert all the functions of the K vitamins. Menadione is metabolized by the human body into K2which uses alkylation to yield menaquinones (MK-n, n=1-13; K2vitamers), hence is better classified as a provitamin.It is also known as "menaphthone".

Low-dose menadione is still used as an inexpensive micronutrient for livestock in many countries.SpecificationFAQQuestion 1:Can you supply free samples ?
