In addition, vitamin K has carboxylation-independent functions. Akin to ubiquinone, vitamin K acts as an electron carrier for ATP production in some organisms and prevents ferroptosis, a type of cell death hallmarked by lipid peroxidation. In this Perspective, we provide an overview of the diverse...

Vitamin - A, D, E, K: The four fat-soluble vitamin groups are A, D, E, and K; they are related structurally in that all have as a basic structural unit of the molecule a five-carbon isoprene segment, which is Each of the fat-soluble vitamin groups conta
though they are also designated by chemical names, such asniacinandfolic acid. Biochemists traditionally separate them into two groups, the water-soluble vitamins and the fat-soluble vitamins. The common and chemical names of vitamins of both groups, along with their main biological functions and...
Vitamin K2 comes in several varieties, identified with MK plus a number that indicates its molecular structure. Menaquinone-4 (MK-4) and MK-7 are the only two that are available in supplement form. And their functions are the most well-studied. ...
Vitamin K is divided into K1 (phylloquinone) and K2 (menaquinone), which have the similar functions but different characteristics depending on their bioavailability and bioactivity1. Vitamin K2, the main storage form of vitamin K in animals, is subdivided into homologues depending on the length of...
