Functions of Vitamin A B C D E - Everything You Need To Know

Functions of Vitamin A B C D E: People require trace amounts of vitamins, which are organic substances. Each plays a unique part in preserving health and physical function. Depending on their lifestyle and general health, individuals may need supplements to improve their supply.

Vitamin needs vary depending on the organism. For instance, although dogs can produce all the vitamin C they require, humans cannot produce enough vitamin C and must include a diet rich in vitamin C. The majority of vitamins must be obtained through food because the body either does not manufacture them at all or generates very little of them; Vitamin D is not present in sufficient levels in the diet of humans. The most significant source of vitamin D is sunshine exposure, which the body uses to create the vitamin. This article will focus mainly on Vitamin A, B, C, D and E functions, their sources, structure and other details.

Macro and Micronutrients

Macronutrients, which comprise the majority of nutrients in the diet, support the development and working of your body. You usually require a lot of macronutrients to keep your body functioning correctly. Proteins, lipids, and carbs are the three macronutrients that give your body the calories it needs for energy. Micronutrients include vitamins and minerals. The units of measurement are milligrammes (mg), micrograms (mcg), or international units (IU). Your body requires fewer micronutrients than macronutrients for optimal functioning. Although they don't produce energy, micronutrients are necessary for digestion, hormone synthesis, and brain function. Quantifying and estimating how much micronutrients you take daily can also be challenging, even though tracking your macronutrients might be advantageous.

Examples of Macronutrients

Foods that typically fit into one of the three macronutrient categories are broken down during digestion and utilised for various purposes. Several macronutrients are:
  • Carbohydrates. Carbs are the body's primary energy source and help with digestion and satiety by converting to glucose. Bread, rice, pasta, cereals, fruits, starchy vegetables, beans, milk, and yoghurt are all carbohydrates. They have a calorie count of 4 per gramme.
  • Fat. Fats contain the fat-soluble vitamins A, D, E, and K and are broken down into fatty acids and glycerol. 9 calories per gramme are included in nuts, seeds, oils, butter, sour cream, mayonnaise, and cream cheese.
  • Protein. In addition to helping with hormone regulation, protein aids in the growth and repair of muscles, tissues, and organs.

Fossils Tracing Evolution

Examples of Micronutrients:

  • B1 vitamin. Vitamin B1, sometimes called thiamine, helps turn food into energy. White rice, fortified breakfast cereals, and black beans are examples of foods.
  • B2 vitamin. This vitamin, also known as riboflavin, is beneficial for cellular health, fat metabolism, and energy generation. Foods include milk, fat-free yoghurt, and quick oats.
  • B3 vitamin. Vitamin B3, often known as niacin, promotes energy synthesis from meals. Salmon, tuna, chicken breast, and turkey breast are examples of foods.
  • B5 vitamin. This vitamin, also known as pantothenic acid, aids in producing fatty acids. Shitake mushrooms, sunflower seeds, and avocados are examples of foods.
  • B6 vitamin. Vitamin B6, also known as pyridoxine, helps produce red blood cells and assists your body in releasing sugar from stored carbs for energy. Chickpeas, tuna, and potatoes are among the foods.
  • B7 vitamin. It facilitates the metabolism of fatty acids, amino acids, and glucose and is known as biotin. Eggs, salmon, pork chops, and sweet potatoes are foods.
  • B9 vitamin. Also known as folate. For healthy cell division, vitamin B9 is crucial. White rice, asparagus, fortified morning cereals, spinach, and other foods are examples.
  • B12 vitamin. Also known as cobalamin, it aids in producing red blood cells and ensures appropriate nervous system and brain operation. Beef liver, salmon, milk, and yoghurt are foods with this vitamin.
  • Vitamin C, sometimes called ascorbic acid, is necessary for synthesising collagen and neurotransmitters. Red peppers, oranges, grapefruits, and kiwis are examples of foods.

Good examples of minerals that are micronutrients include

  • Calcium. This mineral supports healthy muscle function and the development of strong bones and teeth. Yoghurt, orange juice, cheese, and milk are examples of foods.
  • Magnesium. This mineral, which may be found in foods like spinach, almonds, and pumpkin seeds, helps to regulate blood pressure.
  • Sodium. For the best fluid balance and blood pressure maintenance, you need salt.
  • Potassium. Potassium supports neuron and muscle communication. Foods like apricots, lentils, prunes, and raisins all contain potassium.

Vitamins: Definition

The term "vitamin," which is derived from "vita," which means "life," and "amine," which refers to a nitrogenous element necessary for living, was first used in a study report by scientist Casimir Funk in 1912 and was adopted by the medical world.
  • Vitamins are chemical compounds that can be categorised as either fat-soluble or water-soluble. Vitamins that dissolve in fat, including vitamins A, D, E, and K, tend to build up in the body.
  • Vitamins that require dissolved in water to be absorbed by the body (such as vitamin C and the B-complex vitamins, including vitamin B6, vitamin B12, and folate) cannot be stored. The body largely excretes any water-soluble vitamins it does not utilise through urine.
  • Since their discovery in the late 1800s and early 1900s, vitamin needs and their precise amounts have generated debate. Our knowledge of vitamins and minerals in the present day results from the joint efforts of epidemiologists, doctors, chemists, and physiologists.
After many years of observation, research, and trial-and-error, they determined that some illnesses weren't brought on by viruses or poisons, as was the widespread assumption at the time, but rather by vitamin deficiencies. To duplicate a vitamin, chemists tried to determine its chemical composition. Researchers quickly concluded that specific vitamin dosages were required to prevent illnesses caused by vitamin deficiencies. Before the 1930s, supplements of several commercially produced vitamins were exclusively available through food. The U.S. government also started nutrient-fortifying foods to counteract the widespread nutritional inadequacies of the day. Examples include adding iodine to salt to prevent goitre and folic acid to grain products to avoid birth abnormalities during pregnancy. Most vitamins and multivitamins were accessible to the general population in the 1950s to prevent deficiency.

Classification of Vitamins

Vitamins can dissolve or become soluble in fat or water.

Fat-soluble vitamins:

Fat can dissolve the vitamins A, D, E, and K. The body stores fat-soluble vitamins in the liver and adipose tissue, where they can stay for days or even months. Dietary lipids aid the body in absorbing fat-soluble vitamins through the digestive system.

Food Adulteration

Water-soluble vitamins

Water-soluble vitamins can't be stored and don't last very long in the body. Through urine, they go from the body. As a result, humans require a greater regularity of water-soluble vitamins than fat-soluble ones. All B vitamins, including vitamin C, are water-soluble.

Vitamin Deficiency Symptoms

Numerous symptoms, including exhaustion, irritation, and changes to your skin and hair, can be brought on by a vitamin deficiency. The particular symptoms vary depending on which vitamin(s) are deficient since each vitamin has a unique function in your body. For instance, a folate shortage can result in anaemia, which causes exhaustion and weakness, while a vitamin D deficiency can cause weak bones and fractures.

Fungus Life Cycle

Low vitamin consumption or specific medical conditions might lead to a deficit. Vitamin injections or oral (by mouth) supplements are typically used to treat them.
