Vitamins

Dr Dan J Bell and Dr Craig Hacking et al.

Vitamins are a group of organic compounds used in biochemical pathways. Many are components of coenzymes in particular metabolic reactions. Vitamins are generally not synthesised by the human body and hence must be acquired through the diet.

In radiology, there are some imaging manifestations of disease due to abnormally high (hypervitaminosis) and low (hypovitaminosis) levels of particular vitamins.

Vitamins can be classified into fat-soluble and water-soluble compounds.

B-complex vitamins are numbered and by scientific convention the number is subscripted. 

Fat-soluble vitamins

Water-soluble vitamins

NB Vitamins B4, B8, B10, B11, and B13 - B17 have been reclassified and no longer meet the biochemical definition of vitamins or are only vitamins in non-human species.
