The name soon became synonymous with Hopkins' "accessory factors," and by the time it was shown that not all vitamins were amines, the word was already ubiquitous.
A secondary deficiency may be due to a lifestyle factor, such as smoking, excessive alcohol consumption, or the use of certain medications that interfere with the absorption or the body's use of the vitamin.
At the same time, public interest in vitamins has heightened.
A primary deficiency occurs if a person does not get enough of the vitamin in the food he eats.
Vitamins can be classified as either water soluble, which means they dissolve easily in water, or fat soluble, which means they are absorbed through the intestinal tract with the help of lipids.
Throughout the early 1900s, scientists were able to isolate and identify a number of vitamins by depriving animals of them.
One difference was that he used table sugar (sucrose), while other researchers used milk sugar (lactose), which still contained small amounts of vitamin B.
Vitamins are necessary to maintain proper functioning of the nervous system.
Vitamins are organic (carbon-containing) nutrients obtained through the diet and essential in small amounts for normal metabolic reactions.
The likelihood of consuming too much of any vitamin from food is remote, but overdosing from vitamin supplementation can occur.
Vita in Latin is life and the -amine suffix is for amine; at the time it was thought that all vitamins were amines (containing nitrogen).
Vitamins are neither a source of energy nor a source of structural tissue components.
Scientists now have shifted their focus to discovering ways in which vitamins can promote health, prevent disease, boost the body's protection against infection, and even slow down the aging process.
Some vitamins can also be obtained from precursors that can be obtained in the diet.
Vitamins enable the body to use the calories provided by the food that we eat and to help process proteins, carbohydrates, and fats.
When Casimir Funk isolated the water-soluble complex of micronutrients whose bioactivity Fletcher had identified in 1912, he proposed that it be named "Vitamine."
Each food source contains different ratios of vitamins.
Until the 1900s, vitamins could only be obtained by eating food.
Vitamins have only been produced as commodity chemicals and made widely available as inexpensive pills for a few decades (Kirk-Othmer 1984).
The body typically assembles vitamin-dependent catalysts from a variety of building blocks, including amino acids, sugars, phosphates, and vitamins.
Vitamins show the importance of balance in human life.
Vitamins are available by eating a balanced diet including fruits, vegetables, grains, nuts, meat, eggs, fish, and milk.
Each vitamin is typically used in multiple different catalysts and therefore has multiple functions (Kutsky 1973).
Deficiencies of vitamins are either primary or secondary.
Vitamins are normally converted in the body to coenzymes.
According to the World Health Organization, vitamin A deficiency is the most serious vitamin deficiency disease in the world today.
Vitamins are also involved in building cells, tissues, and organs—vitamin C, for example, helps produce healthy skin.
Once growth and development is completed, adults remain dependent upon vitamins to maintain good health.
The ancient Egyptians knew that feeding a patient liver would help cure night blindness, now known to be caused by a vitamin A deficiency.
Vitamins are classified as fat-soluble or water-soluble based on how they are absorbed by the body.
The value of eating certain foods to maintain health was recognized long before vitamins were identified.
Vitamins can act both as catalysts and participants in the chemical reaction.
Vitamin G (Riboflavin), for example, is now known as B2.
In 1920, Jack Cecil Drummond proposed that the final "e" be dropped, to deemphasize the "amine" reference, after the discovery that vitamin C had no amine component, and the name has been "vitamin" ever since.
Like enzymes, which are also catalysts, vitamins are essential in small quantities.
Well-known vitamin deficiencies are thiamine (beriberi), niacin (pellagra), vitamin C (scurvy) and vitamin D (rickets).
Vitamin B3 plays a crucial role in the synthesis of serotonin and has been shown to help with anxiety at a dosage of 1,000-3,000mg per day. ... Vitamin B9 (also known as folate or folic acid) and vitamin B12 are important in balancing out depressive moods.May 20, 2016
