vitamins Flashcards
Apart from the normal food that we take, our body requires a certain number of compounds in small amounts for the proper functioning and deficiency of these compounds may cause diseases. These compounds are known as vitamins.
Is an organic molecule that is an essential micronutrient which an organism needs in small quantities for the proper functioning of its metabolism.
VITAMINS
Essential nutrients cannot be synthesized in the organism, either at all or not in sufficient quantities, and therefore must be obtained through the diet.
Are organic compounds that people need in small quantities. Most of these need to come from food because the body either does not produce them or produces very little. Each organism has different vitamin requirements.
VITAMINS
Are chemical compounds that are required in small amounts with our regular diet in order to carry out certain biological functions and for the maintenance of our growth.
VITAMINS
Travel freely through the body, and excess amounts usually are excreted by the kidneys. The body needs these in frequent, small doses.
WATER-SOLUBLE VITAMINS
This vitamin, at high levels over a long period of time has been shown to cause irreversible nerve damage.
PYRIDOXINE
These vitamins have upper consumption limits.
Niacin
Choline
Pyridoxine
Folate
Ascorbic acid
A balanced diet usually provides enough of these vitamins. People older than 50 and some vegetarians may need to use supplements to get enough B12.
Are stored in the body’s cells and are not excreted as easily as water-soluble vitamins. They do not need to be consumed as often as water-soluble vitamins, although adequate amounts are needed. If you take too much of these, it could become toxic.
FAT-SOLUBLE VITAMINS
A balanced diet usually provides enough fat-soluble vitamins. You may find it more difficult to get enough vitamin D from food alone and may consider taking a vitamin D supplement or a multivitamin with vitamin D in it.
Vitamins in B-group and Vitamin C are Water-Soluble and cannot be stored in our bodies as they pass with
the water in urine. These vitamins must be supplied to our bodies with regular diets.
