The term vitamin is derived from the words vital and amine.
Although not all vitamins are amines Vitamins are organic compound and an
essential nutrient that an organism requires in limited amounts. For example,
ascorbic acid (vitamin C) is a vitamin for humans, but not for most other
animals, and biotin and vitamin D are required in the human diet only in
certain circumstances.
Biotin promote healthy hair and strong nail and also support
cellular energy production.
History:
In 1749, the Scottish surgeon James [ia1] Lind discovered that citrus foods Plants in the genus produce
citrus fruits, including important crops like oranges, lemons, grapefruit,
pomelo and limes. These foods
helped prevent scurvy. Scurvy is a condition characterized by general weakness,
anemia bleeding of the gums, (gum
disease)
In 1753
James Lind published his researches on the Scurvy, which recommended using
lemons and limes to avoid scurvy.
In the
early 20th century, the prevailing medical theory was that scurvy was caused by
canned food.
Christiaan
Eijkman, in 1897 discovered that feeding unpolished rice instead of the
polished variety to chickens helped to prevent beriberi in the chickens.
The
following year, Frederick Hopkins postulated that some foods contained
"accessory factors" in addition to proteins, carbohydrates, fats, et
cetera — that are necessary for the functions of the human body.
Hopkins
and Eijkman were awarded the Nobel Prize for Physiology or Medicine in 1929 for
their discovery of several vitamins.
