What Is Vitamin
A vitamin is a natural compound and a vital nutrient that an organism requires in restricted amounts. A natural chemical compound (or relevant set of substances) is called a vitamin when the organism can not manufacture the substance in sufficient quantities, and it must be obtained through the diet plan; hence, the term “vitamin” is conditional upon the scenarios and the particular organism. For example, ascorbic acid (one kind of vitamin C) is a vitamin for people, but not for most other animal organisms. Supplements is very important for the treatment of certain health problems, however there is little proof of nutritional benefit when made use of by otherwise healthy individuals.
By convention, the term vitamin consists of neither other essential nutrients, such as dietary minerals, essential fatty acids, or essential amino acids (which are required in higher quantities than vitamins) nor the great number of other nutrients that promote health, and are needed less commonly to maintain the health of the organism. Thirteen vitamins are generally acknowledged at present. Vitamins are classified by their biological and chemical activity, not their structure. Hence, each “vitamin” refers to a variety of vitamer substances that all reveal the biological activity related to a particular vitamin. Such a set of chemicals is grouped under an alphabetized vitamin “generic descriptor” title, such as “vitamin A”, which includes the substances retinal, retinol, and 4 understood carotenoids. Vitamers by definition are exchangeable to the active type of the vitamin in the body, and are occasionally inter-convertible to one another, also.
Vitamins have varied biochemical functions. Some, such as vitamin D, have hormone-like functions as regulatory authorities of mineral metabolic rate, or regulatory authorities of cell and tissue development and differentiation (such as some forms of vitamin A). Others operate as antioxidants (e.g., vitamin E and in some cases vitamin C). The biggest variety of vitamins, the B complex vitamins, function as precursors for enzyme cofactors, that assistance enzymes in their work as catalysts in metabolic rate. In this role, vitamins may be firmly bound to enzymes as part of prosthetic groups: For example, biotin belongs to enzymes involved in making fatty acids. They may likewise be less tightly bound to enzyme catalysts as coenzymes, removable particles that work to carry chemical groups or electrons between molecules. For instance, folic acid may carry methyl, formyl, and methylene groups in the cell. Although these functions in assisting enzyme-substrate responses are vitamins’ best-known function, the other vitamin functions are similarly important.
Till the mid-1930s, when the first industrial yeast-extract vitamin B complex and semi-synthetic vitamin C supplement tablets were sold, vitamins were gotten entirely through food consumption, and modifications in diet (which, for example, could occur during a specific growing season) normally significantly modified the types and amounts of vitamins ingested. Nevertheless, vitamins have actually been produced as commodity chemicals and made extensively readily available as affordable semisynthetic and synthetic-source multivitamin dietary and food supplements and additives, because the middle of the 20th century. Study of structural activity, function and their role in maintaining health is called as vitaminology.
Too Much of Vitamins
Too much of a good thing can be a bad thing. We all learn about Vitamins-at least we believe we do. Vitamins are essential dietary elements (in other words they are acquired from food sources) which the body requires in proper amounts for cell maintenance, function & growth.
Some Vitamins taken in excess can be dangerous!! Vitamin A is an example of too much causing us damage!! Deficiency of this vital chemical leads to Night Blindness, scaly-dry skin, abnormalities of smell and cravings, and dental problems.
However-too much causes Cirrhosis of the Liver, loss of bone mass & Osteoporosis, reduction in mental alertness, and problems of the skin & hair and even Birth Defects.
Excellent Natural sources of Vitamin A consist of: vegetables or fruits that are orange or yellow, dark green, leafy veggies like spinach, broccoli, and asparagus to name just a couple of.
Constantly contact your medical professional prior to taking Vitamins in big amounts; while some clients might “regularly” require supplementation (such as those with Inflammatory Bowel Disease), for others the outcomes can be disastrous.
