BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The body needs vitamin D to absorb calcium. Without enough vitamin D, one can’t form enough of the hormone calcitriol (known as the “active vitamin D”). This in turn leads to insufficient calcium absorption from the diet.

Detailed explanation-2: -The principal function of vitamin D in calcium homeostasis is to increase calcium absorption from the intestine. Calcium is absorbed by both an active transcellular pathway, which is energy dependent, and by a passive paracellular pathway through tight junctions.

Detailed explanation-3: -“For better absorption of vitamin D, you must include vitamin K, magnesium, and zinc in your diet. They speed up the absorption procedure and reduce your likelihood of being vitamin D deficient, ” she suggests.

Detailed explanation-4: -Vitamin D enhances intestinal absorption of calcium and phosphate. Low concentrations of vitamin D are associated with impaired calcium absorption, a negative calcium balance, and a compensatory rise in parathyroid hormone (PTH), which results in excessive bone resorption.
