General Information

The two primary isomers of carotene, a-carotene and b-carotene, differ in the position of double bonds in the cyclic group at the end of the molecule.

Plasma carotenes concentrations in general reflect dietary intake. Dietary assessment is usually all that is necessary, but measurement is occasionally helpful in establishing whether an unusual skin colouration is due to hypercarotenaemia or not.

Patient Preparation

None

Notes
