What are the 5 water soluble vitamins?
The water-soluble vitamins include ascorbic acid (vitamin C), thiamin, riboflavin, niacin, vitamin B6 (pyridoxine, pyridoxal, and pyridoxamine), folacin, vitamin B12, biotin, and pantothenic acid.
What are properties of water soluble vitamins?
Water-soluble vitamins are those that are dissolved in water and readily absorbed into tissues for immediate use. Because they are not stored in the body, they need to be replenished regularly in our diet. Any excess of water-soluble vitamins is quickly excreted in urine and will rarely accumulate to toxic levels.
What do most water soluble vitamins function as?
Water-soluble vitamins travel freely through the body, and excess amounts usually are excreted by the kidneys. The body needs water-soluble vitamins in frequent, small doses….Water-soluble vitamins.
| Nutrient | Function | Sources |
|---|---|---|
| Pantothenic acid | Part of an enzyme needed for energy metabolism | Widespread in foods |
What are the 8 water soluble vitamins?

- Vitamin B5 (pantothenic acid)
- Vitamin B6.
- Vitamin B7 (biotin)

How are water soluble vitamins absorbed?
In general, water-soluble vitamins undergo intestinal absorption by active transport processes across enterocyte membranes, followed by transport to the liver and peripheral tissues in the portal and systemic circulations.
How are water soluble vitamins metabolized?
Metabolism. The water-soluble vitamins are absorbed in the animal intestine, pass directly to the blood, and are carried to the tissues in which they will be utilized. Vitamin B12 requires a substance known as intrinsic factor in order to be absorbed.
How are water soluble vitamins excreted?
Water-soluble vitamins travel freely through the body, and excess amounts usually are excreted by the kidneys. The body needs water-soluble vitamins in frequent, small doses. These vitamins are not as likely as fat-soluble vitamins to reach toxic levels.
Which water soluble vitamins that have a functional role in gene expression?
Biotin participates in the regulation, both at mRNA and protein level, of the enzymes that participate in its own metabolic cycle and of enzymes that contribute to glucose metabolism. Thiamine regulates the expression of some genes that code for enzymes using thiamine diphosphate as cofactor.
Where are water soluble vitamins stored in the body quizlet?

How are water soluble vitamins stored in the body?
Vitamins play a vital role in many biochemical functions in the human body and are essential components for maintaining optimal health. There are two main groups of vitamins – fat-soluble (easily stored in fat upon absorption) and water-soluble (washed out and not easily stored).
What is the chemical structure of a vitamin?
The Chemical Structures of Vitamins. A vitamin is defined as any organic compound that a living organism requires, but which it is not capable of producing itself, or cannot produce in the amounts required by the body. As far as the definition for vitamins goes, this doesn’t include the other essential nutrients that are found in our diet,…
How does the solubility of vitamins affect its use?
A vitamin’s solubility in water or in lipids determines where it can be use d a nd whether it will be stored in fat cells or excreted from the body if it is not needed for immediate use. Vitamin Solubility Molecular Basis for Water Solubility and Fat Solubility
Are there any B vitamins that are water soluble?
B complex vitamins are also prone to loss during feed processing. B vitamins are water soluble and are needed in the daily diet of monogastric animals. Thiamine consists of one molecule of pyrimidine joined with one of thiazole. Thiamin is also referred to as vitamin B1, as it is the first vitamin identified.
