Carotenes are photosynthetic pigments important for photosynthesis. Carotenes contain no oxygen atoms. They absorb ultraviolet, violet, and blue light and scatter orange or red light, and yellow light (in low concentrations).

2023年5月23日 · Beta carotene is an antioxidant that converts to vitamin A and plays a very important role in health. Learn about health benefits, risks, and food sources.

β-Carotene (beta-carotene) is an organic, strongly colored red-orange pigment abundant in fungi, [7] plants, and fruits. It is a member of the carotenes, which are terpenoids (isoprenoids), synthesized biochemically from eight isoprene units and thus having 40 carbons.

2023年10月18日 · Beta-carotene is a special kind of carotenoid known as a provitamin A carotenoid. That means it’s essentially a precursor to vitamin A. “When it’s absorbed in your body, beta-carotene transforms into vitamin A in your intestines,” Sedlacek explains.

2024年9月21日 · Beta carotene, a type of carotenoid, transforms into vitamin A in the body. Vitamin A supports healthy vision, immunity, skin health, and cognitive function. Because it's an antioxidant, it's also been known to reduce oxidative stress.

2017年12月14日 · Beta carotene is a red-orange pigment found in plants and fruits, especially carrots and colorful vegetables. The body converts beta carotene into vitamin A, which is an essential vitamin. The...

Carotene, any of several organic compounds widely distributed as pigments in plants and animals and converted in the livers of many animals into vitamin A. These pigments are unsaturated hydrocarbons (having many double bonds), belonging to the isoprenoid series.

Beta-carotene is found in carrots; dark-green leafy vegetables, such as spinach and green leaf lettuce; sweet potatoes; broccoli; cantaloupe; and winter squash. The body converts beta-carotene into vitamin A. Ordinary cooking does not destroy beta-carotene.

2023年7月12日 · Carotenes are non-oxygen-containing molecules, and they’re orange-pigmented. Common examples include beta-carotene (hello, carrots!) and lycopene (watermelon is full of it). What do carotenoids do for your body? While artificial dyes and pigments can pose health risks, carotenoids have zero downsides.
