Vitamins Essential Nutrients

The essential nutrients are non-energy-yielding micronutrients: the vitamins and minerals
In my blog we will focus on vitamins.
We’ll view both fat-soluble and water soluble vitamins. We’ll focus on why we need them and how we may obtain them, also we will describe how vitamins my help to prevent chronic disease in ways over and above their usual roles in body functions. Attitudes toward our health and uses of vitamin have varied widely, from wise functional use to wild flagrant abuse.
There are four fat-soluble vitamins and ten water-soluble vitamins.
Fat-Soluble vitamins
  1. Vitamin A
  2. Vitamin D
  3. Vitamin E
  4. Vitamin K

Water-Soluble vitamins
  1. Vitamin C
  2. B vitamins
  3. Thiamin
  4. Riboflavin
  5. Niacin
  6. Pyridoxine (vitamin B6)
  7. Pantothenic Acid
  8. Biotin
  9. Folate
  10. Cobalamin (vitamin B12)

Vitamin discovery during the years from 1900 to 1950 was rapid remarkable.  General nature and classification of study of vitamins: the essential nutrients came into three evident characteristics: ( 1) they were not metabolize to yield energy as were carbohydrate, fat, and protein; (2) they were vital to life; and (3) often not a single substance but a group of related substance turned out to have the particular metabolic activity.
The name Vitamin developed during the early research years when one of the scientists working with a nitrogen-containing chemical substance called an amine thought this was the common nature of all of these vital molecules. So he named his discovery vitamin (“vital amine”). Later the final “e” was dropped when other similarly vital substances turned out to have different organic structures, but the name vitamin has been retained to designate compounds of this class of essential substance. At first, letter names were given to individual vitamins as they were discovered but as the number of known vitamins increased rapidly, this practice created confusion. Thus in recent years more specific scientific names based on structure or functions were developed. However, for the fat-soluble vitamins, their letter names have been retained for clarity because in each case a number of closely related compounds with similar properties and structures are well known.
