Vitamin D is a fat-soluble vitamin that can be found in food but significant amounts of vitamin D can also be produced by the body. It can be obtained from sun exposure‚ food‚ and supplements are biologically inert and must undergo two hydroxylations in the body for activation. The two major forms of which are vitamins D2 (ergocalciferol) and vitamin D3 (cholecalciferol). This paper not only looks into the essential function of vitamin D on the subject of bone health‚ but also other non-calcemic

IB Biology Lab – Vitamin C content of food Aim: To compare the vitamin C content of different fruits using the decolourisation of DCPIP from blue to clear as the indicator. • You first need to estimate the volume of a known concentration of vitamin C solution required to decolourise 2 cm3 of DCPIP solution. • Then you need to determine the volume of fruit juice that decolourises 2 cm3 of DCPIP solution. This gives an estimate of the concentration of vitamin C in fruit juice. • This

VITAMIN D (CALCITRIOL) INTRODUCTION: Bioactive vitamin D or calcitriol is a steroid hormone that has long been known for its important role in regulating body levels of calcium and phosphorus‚ and in mineralization of bone. More recently‚ it has become clear that receptors for vitamin D are present in a wide variety of cells‚ and that this hormone has biologic effects which extend far beyond control of mineral metabolism. Vitamin D is thus not

(neuromuscular spasm) develops. In infants and young children‚ a long-standing calcium intake deficiency‚ in association with suboptimal vitamin D exposure‚ can produce rickets. Indeed‚ in experimental animals and in humans with extremely low vitamin D levels‚ genetic absence of calcitriol (vitamin D–dependent rickets [VDDR] type I)‚ or genetic absence of the vitamin D receptor (VDDR type II)‚ the use of increased calcium supplementation or calcium infusions will prevent and treat rickets. These observations

Lab Report: MEASUREMENT OF VITAMIN C Introduction Nutritional diseases were once the number one cause of death only a century ago‚ but rarely affect our lives today.
