Applications Thyroxine is one of the thyroid hormones involved in the maintenance of metabolic homeostasis. Synthesized and stored as amino acid residues of thyroglobulin, the major protein component of the thyroid follicular colloid. Synthesis and secretion are regulated by the pituitary hormone (TSH). Deiodinated in peripheral tissues to the active metabolite, liothyronine. The D-form has very little activity as a thyroid hormone, but has been used to treat hyperlipidemia.

Applications Menaquinones are isoprenoid quinones of the naphthalene series and belongs to the K2 Vitamin homologs. Menaquinones were originally discovered as the anti-hemorrhagic factor and now encompasses a variety of physiological processes. Menaquinone 7 belongs to the class of K2-Vitamins homologs. Menaquinone 7 has been identified as the most bioactive cofactor for the carboxylation reaction of Gla-proteins such as osteocalcin and matrix-Gla protein, which plays a crucial role in building and maintaining overall bone health.
