Increased ca and phosphate deposits Active Vitamin D Ultraviolet light (UVB) Reduced excretion of Vitamin D 7-dehydrocholesterol Uver 25-OH Vitamin D calcidiol Kidneys 1.25-di-OH Vitamin D calcitriol Increased absorption of Cat and phosphate Vitamin D, calciferol, comes from both plant and animal food sources. The plant form of vitamin D is called vitamin D2, or ergocalciferol, whereas the animal form is vitamin D3, also called cholecalciferol. The body can also make vitamin D when skin cells are exposed to the sun's ultraviolet radiation, which is why vitamin D is often referred to as the "sunshine vitamin." Ultraviolet radiation converts a substance in skin that is derived from cholesterol, 7-dehydrocholesterol, into a prohormone called vitamin D3. Vitamin D3 circulates to the liver, where the substance is converted to the inactive compound 25- hydroxyvitamin D (calcidiol). Blood levels of 25-hydroxyvitamin D are used to determine vitamin D status. Eventually, the kidneys convert 25-hydroxyvitamin D into the most biologically active form of vitamin D, 1,25-dihydroxyvitamin D (calcitriol) Full activation of vitamin D requires both a healthy liver and healthy kidneys A deficiency of vitamin D in children results in rickets, which contributes to improper bone growth in adults, the deficiency disorder is osteomalacia, a condition characterized by softening of the bones. It is not uncommon for people with osteomalacia to also have osteoporosis, a condition characterized by loss of bone mass that usually occurs with aging.

Answer 1

Ergocalciferol. is a plant form of Vitamin D.

Answer - Ergocalciferol

2. Calicidiol is converted into calcitriol in the kidneys.

Calcidiol is hydroxylated in our kidney to form calcitriol

Answer - kidneys

3. Blood level 25 hydroxyvitamin D measure is most often used to assess an individual's Vitamin D status.

The normal value of 25 hydroxyvitamin D in the blood is 25 to 80 ng per ml.

Answer -Blood levels of  25 hydroxyvitamin D

4.

The deficiency of Vitamin D in adults leads to Osteomalacia.

Osteomalacia is known as the softening of bones due to improper bone metabolism.

Answer - Osteomalacia
