α-Carotene is a form of carotene with a β-ionone ring at one end and an α-ionone ring at the opposite end. It is the second most common form of carotene.

In United States adults and Chinese adults the mean concentration of serum α-carotene was 4.71 µg/dL, including 4.22 µg/dL among men and 5.31 µg/dL among women (to convert to micromoles per liter, multiply by 0.01863).
