Vitamin C contributing to the more severe symptoms of scurvy. More generally, the biochemical role of vitamin C is to act as an antioxidant (a reducing agent) by donating electrons to various enzymatic and non-enzymatic reactions. Doing so converts vitamin C to an oxidized state - either as semidehydroascorbic acid or dehydroascorbic acid. These compounds can be restored to a reduced state by glutathione and NADPH-dependent enzymatic mechanisms. In plants, vitamin C is a substrate for ascorbate peroxidase. This enzyme utilizes ascorbate to neutralize toxic hydrogen peroxide (HO) by converting it to water (HO). Scurvy is a disease resulting from a deficiency
Vitamin D deficiency in Australia Nowadays through technological advancements Vitamin D deficiencies are now identified and thus calculated through the measurement of the serum 25-OH. According to the Australian Bureau of Statistics National Health Measures Survey (NHMS), the recommend Vitamin D levels to determine deficiency are categorised as follows: •Adequate levels: > 50 nmol/L •Mild deficiency: 30-49 nmol/L •Moderate deficiency: 13 – 29nmol/L •Severe deficiency: < 13 nmol/L This fundamental fat-soluble vitamin has been long known for its important role in calcium absorption in the body, especially in musculoskeletal health. The health impacts commonly caused by deficiency of Vitamin D are rickets in children and
