in the world
06. This major mineral is located primarily in bone as well as intracellularly
within the body (not calcium, phosphorus, or potassium) and is used as

Explanation / Answer
4) Myelin is composed of lipids and proteins and is white in colour which covers the shaft of the nerve axon. It acts as a insulator and enables conduction of nerve impulses across the cell.
Vitamin B12 which is also known as cobalamin, a water soulble vitamin, It is one of the 8th vitamin of the B vitamin groups.It is very important for the functioning of the nervous system and brain with the help of myelin formation(myelinogenesis). It also enables the formation of red blood cells.
5) Many surveys had been conducted by different countries and the reports are submitted to the World Health Organisation, which reveals Iron deficiency is the commonest form nutrient deficiency in both developed and developing countries. Iron is an important nutrient for formation of red blood cells and maintaining the balance in hemotocrit levels. This deficiency co-exist with many illness such as malaria, HIV/AIDS, Malnutrition, worm infections and tuberculosis. It also affects primarily pregnant women because of the imbalance between increasing demand and decreased intake.
6) Magnesium is available in free state as well ibounding to proteins .It is involved in all the metabolism of the body. It act as an intracellular cation, has been identified as a cofactor in over 300 enzymatic reactions. Magnesium interacts with many nutrients , very notably with Vitamin D, Calcium, Phosphorus and potassium. In an average, an adult body comprised of 22 to 25 grams of magnesium which is 60% in the skeleton, 39% intracellular (20% in skeletal muscle), and 1% extracellular.
