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.

Human physiology[edit]

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).[1]

Health effects[edit]

Dietary intake affects blood levels of α-carotene, which in one study was associated with significantly lower risk of premature death.[1][2]

Dietary sources[edit]

The following vegetables are rich in alpha-carotene:[1]
