BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Vitamin K-dependent carboxylation, an essential posttranslational modification catalyzed by gamma-glutamyl carboxylase, is required for the biological functions of proteins that control blood coagulation, vascular calcification, bone metabolism, and other important physiological processes.

Detailed explanation-2: -Vitamin K helps to make various proteins that are needed for blood clotting and the building of bones.

Detailed explanation-3: -Ever since its initial discovery, vitamin K has been known to be important in the clotting process of blood, because of its involvement in the synthesis of four plasma clotting proteins.

Detailed explanation-4: -Vitamin K1 is also called phylloquinone, phytomenadione or phytonadione and is synthesized in plants, particularly green, leafy vegetables because it is involved in photosynthesis. Vitamin K1 contains the functional naphthoquinone ring, an aliphatic side chain and a phytl side chain.

Detailed explanation-5: -Vitamin K is known as the clotting vitamin. Without it, blood would not clot. Some studies suggest that it helps maintain strong bones in older adults.
