Area of Science:

  • Biochemistry and Molecular Biology
  • Nutritional Science
  • Physiology

Context:

  • Vitamin K is essential for blood coagulation, functioning as a cofactor for gamma-carboxylase.
  • Gla-proteins, like osteocalcin and matrix Gla protein, are involved in calcium deposition in calcifying tissues.
  • Emerging research highlights vitamin K's significant role in bone metabolism, with clinical applications developing.

Purpose:

  • To elucidate the diverse physiological activities of vitamin K2.
  • To compare the functions of vitamin K2 with those of vitamin K1.

Summary:

  • Vitamin K facilitates the conversion of glutamic acid to gamma-carboxyglutamic acid (Gla) residues.
  • Vitamin K2 exhibits various physiological functions beyond coagulation, including glucose metabolism regulation, anti-arteriosclerosis effects, and cell differentiation induction.
