Answer:
Vitamins are a group of chemically diverse organic compounds that an organism requires for normal metabolism. Apart from a few exceptions (e.g.,
vitamin D
), the human body cannot synthesize vitamins on its own in sufficient amounts and must, therefore, ensure a steady supply through the diet. Vitamins are micronutrients that do not provide energy (like
macronutrients
) but instead have very specific biochemical roles. They can be coenzymes in various reactions (B vitamins, vitamins A and K) and/or antioxidants that protect the cell and its membrane from
free radicals
(vitamins C and E). They can also enable cell signaling (
vitamin A
) and
gene transcription
(vitamins A and E) or function as
hormones
(e.g.,
vitamin D
). Vitamins are classified into
fat-soluble vitamins
, which the body can store, and water-soluble vitamins, which, with the exception of vitamins B9 (
folate
) and B12 (
cobalamin
), the body cannot store over significant periods of time and, therefore, require continuous intake. A balanced diet typically supplies the body with all vitamins it requires. Deficiencies occur mainly due to
malnutrition
,
malabsorption
disorders, or restrictive diets (e.g.,
vitamin B12
deficiency in a
vegan diet
).
