Organic compounds In the chemical sense, vitamins are considered organic compounds because they contain the element carbon. Essential Nutrients Vitamins are essential nutrients since the body cannot make them, so we must get vitamins from food and water. Nonessential nutrients are those that the body is able to make in sufficient quantities to meet our need, such as nonessential amino acids.

True or false: Each species has a different vitamin requirement.

True The correct answer is true. The types of vitamins required vary across all species. For example, humans must get vitamin C from the diet, but dogs don't have to get vitamin C from the diet because dogs can make their own vitamin C.

water soluble vitamins

Turnover in the body is fast Excess is excreted Function as coenzymes Water-soluble vitamins turn over in the body very fast (~48 hours to several days), so the body needs water-soluble vitamins frequently. When consumed in excess, water-soluble vitamins are excreted in the urine, so they are not likely to be toxic. Water-soluble vitamins function as coenzymes in the body. Fat-soluble vitamins have a very slow turnover in the body (over a period of months), so the body needs fat-soluble vitamins less frequently as compared to water-soluble vitamins. Toxicity can be a risk with some fat-soluble vitamins, since fat-soluble vitamins are stored in the body when they are consumed in excess. Fat-soluble vitamins function mainly function in general roles in the body, as compared to water-soluble vitamins.

Water Soluble Vitamins

Water-Soluble Vitamins Deficiency

1. tissue levels of vitamin decline steadily 2. biochemical lesion develops (enzyme activity decreases) 3. clinical lesion develops (outward sign of deficiency) Water-soluble vitamin deficiencies develop over several weeks. After consuming a water-soluble vitamin-deficient diet, tissue levels of the vitamin decrease, since the body needs to use the vitamin to perform essential functions. Biochemical lesions (decreased enzyme activity) result at around 3-4 weeks. At around 6-8 weeks, clinical lesions appear. Clinical lesions are outward signs of deficiency that include changes in appearance of the tongue and skin, muscle fatigue, and more.

Thiamin and niacin both work as coenzymes in ___________ energy metabolism.

Carbohydrate Most of the B vitamins are coenzymes in energy metabolism. Thiamin and niacin function as coenzymes in carbohydrate energy metabolism. Niacin also functions as a coenzyme in protein and fat metabolism.
