Vitamin, any of several organic substances that are necessary in small quantities for normal health and growth in higher forms of animal life. Vitamins are distinct in several ways from other biologically important compounds such as proteins, carbohydrates, and lipids. Although these latter substances also are indispensable for proper bodily functions, almost all of them can be synthesized by animals in . Jun 22, · Vitamins are made by living things, while minerals are found in the earth. For example, carrots produce beta carotene, which the body turns into vitamin A; minerals, such as iron and copper, can be found in soil and rock.

Vitamins are made by living things, while minerals are found in the earth. For example, carrots produce beta carotene, which the body turns into vitamin A; minerals, such as iron and copper, can be found in soil and rock. Vitamins are much more delicate than minerals and can break down with heat or age, and they are organic; minerals are inorganic, making their chemical form more simple than that of vitamins.
Whereas all vitamins are needed by the body, only some minerals are required for nutrition. Examples of necessary minerals include calcium, chromium, copper, iodine, iron, magnesium, manganese, phosphorus, potassium, sulfur, sodium, and zinc. Minerals and trace elements are mainly found in meat, cereals, fish, milk and what are vitamins made up of foods, vegetables, dried fruit, and nuts.

When taken in excess, water-soluble vitamins are removed from the body through urine. Vitamins A, D, E, and K, the fat-soluble vitamins, bind to fat in the stomach and are then stored in fatty tissues and the liver.
These vitamins are not excreted readily, and when taken in excess, they can build up in the body and lead to unwanted, and potentially dangerous, adverse effects. Antioxidants are substances that may prevent or delay some types of cell damage by counteracting free radicals— chemicals that can harm cells. Examples of antioxidants include vitamins A, C, and E; beta carotene; lycopene; and selenium. Although antioxidants naturally found in fruits, vegetables, and grains may help to prevent certain diseases, research has not shown what are vitamins made up of high doses of antioxidant supplements prevent disease.
Widely known for what if my baby throws up medicine importance to good vision, vitamin A also supports the immune system and is necessary for a healthy pregnancy. Vitamin A deficiency is rare in the United States; it is largely a problem of developing countries. Vitamin A can come from both plant and animal sources. Plant sources include leafy green vegetables and orange and yellow fruits and vegetables.
Animal sources include liver, salmon, and whole milk. Vitamin A is also added to fortified cereals, is a part of most multivitamins, and is available as a stand-alone supplement.

Liver, fish, chicken, lean red meat, nuts, whole grains, dried beans, and enriched refined grains.
Helps break down protein; helps maintain the health of red blood cells, the nervous system, and parts of the immune system. Helps the cells in the body make and maintain DNA; important for the production of red blood cells. Leafy green vegetables, liver, citrus fruits, mushrooms, nuts, peas, dried beans, and wheat bread. Vitamin B 9 folic acid can help prevent birth defects of the brain and spine, known as neural tube defects. It is recommended that all women who are capable of becoming pregnant consume mcg per day of folic acid from fortified foods or from dietary supplements.
Vitamin B 12 is important for nerve function and development. A deficiency can cause symptoms such as numbness, weakness, difficulty walking, yellowed skin, and memory loss. The elderly, vegetarians, vegans, and people who have undergone weight loss surgery are at risk of developing a vitamin B 12 deficiency. Vitamin C is necessary for growth and repair of tissues in all parts of the body. You may have also seen ads touting the benefits of vitamin C during cold and flu season, but these claims continue to be the source of great debate.
Although research shows that vitamin C supplements do not reduce the risk of getting the common cold for most people, regular vitamin C supplement intake may help to shorten cold duration and reduce symptom severity.
Using vitamin C supplements after cold symptoms begin does not appear to be helpful. Research conducted over the past decade what does hajj mean to muslims that vitamin D, besides building strong bones, may play an important role in preventing and treating a number of serious long-term health problems, such as osteoporosis, heart disease, some cancers, and multiple sclerosis.
Vitamin D is both a nutrient in food and a hormone our bodies make through sun exposure. It is important for bone health because one of its main functions is helping the body absorb calcium. Few foods are naturally rich in vitamin D. The best dietary sources of vitamin D are fatty fish, such as salmon, tuna, and mackerel; fortified dairy products; and breakfast cereals. Vitamin E is used for cell communication, to strengthen the immune system, and to form red blood cells. Much like vitamin D helps the body use calcium, vitamin E helps the body use vitamin K.

Essential nutrients for your body
Jan 13, · Currently, there are 13 recognised vitamins: vitamins A to E, including a range of B vitamins, and vitamin K. The slightly odd gap in lettering between E and K is a consequence of changes in designations of vitamins; for example, vitamin B7, biotin, was previously referred to as vitamin H. Apr 24, · The process of making vitamins is complex. It involves a lot of organization and a lot of inspections to make sure the various vitamins are up to par. Here's. What they do Release energy.. Several B vitamins are key components of certain coenzymes (molecules that aid enzymes) that help Produce energy.. Thiamin, riboflavin, niacin, pantothenic acid, and biotin engage in energy production. Build proteins and cells.. Vitamins B6, B12, and folic acid.
Vitamins fall into the class of molecules known as micronutrients, which are molecules that humans require in small quantities to maintain normal cellular function. They don't provide calories, but do assist in a variety of different chemical reactions in the body. Like all biomolecules, vitamins consist mostly of the elements carbon, hydrogen, oxygen and nitrogen, with a few other elements featured occasionally. Carbon is considered the "backbone element" of the molecules of life. This is because of all the elements on the periodic table, carbon is the one that allows for the greatest potential variety of shapes in resulting molecules and forms the strongest, most stable bonds.
As a backbone element, carbon provides a molecule's overall shape and structure but doesn't contribute as significantly to function as other elements do. All vitamins have carbon backbones, Drs. Reginald Garrett and Charles Grisham note in their book "Biochemistry. Like carbon, hydrogen is a part of a molecule's general shape and structure.
Hydrogen is the lightest element, and also the most common by sheer number in the molecules of life. All vitamins have significant quantities of hydrogen in them. Most hydrogen atoms on any given molecule simply provide for the molecule's overall shape rather than participating in chemical reactions, but in some cases, hydrogen is an important part of a vitamin's reactivity. For example, it's hydrogen that's responsible for the acidic nature of vitamin C.
While oxygen and nitrogen aren't as prevalent in vitamins as carbon and hydrogen, they're nevertheless present -- one or both -- in all vitamins, and contribute significantly to functionality. Oxygen atoms in vitamin C are largely responsible for the molecule's antioxidant properties, while nitrogen atoms in the B-vitamins allow them to participate in regulating metabolism. Some vitamins, including vitamin B-6, contain both nitrogen and oxygen.
Apart from the four elements most common in vitamins, there are several elements that show up only in a few vitamins. For instance, both vitamins B-6 and B contain phosphorus, Drs. Mary Campbell and Shawn Farrell note in their book "Biochemistry. Vitamin B-1, also called thiamine, contains sulfur, which has chemical reactivity similar to that of oxygen. One of the most unique elements in a vitamin is cobalt, found in vitamin B Kirstin Hendrickson is a writer, teacher, coach, athlete and author of the textbook "Chemistry In The World.
