Carotene.alpha

Active

Description

Vitamin A plays a role in several important physiological processes, including vision, embryonic development, gene expression, and immune function. The major source of dietary vitamin A is in the form of provitamin A carotenoids, which are found in vegetables, fruits and grains, and about one-third is consumed as preformed vitamin A, which is found in dairy and meat products. Provitamin A carotenoids include beta-carotene, alpha-carotene, and beta-cryptoxanthin, and both alpha-carotene and beta-cryptoxanthin have about half the vitamin A activity of beta-carotene. Carrots are the major contributor to both alpha- and beta-carotene, and cantaloupe, broccoli, squash, peas, and spinach also contain beta-carotene. Fruits are the sole contributors of beta-cryptoxanthin. [NCBI Books: NBK222318] Source: Regenstrief LOINC, NCBI Books: NBK222318
