karoteenidel

Karoteenidel are a class of organic compounds that are widely distributed in nature. They are a type of terpenoid, which are built from isoprene units. The most well-known carotenoid is beta-carotene, which is found in carrots and is responsible for their orange color. Other common carotenoids include alpha-carotene, lutein, zeaxanthin, and lycopene.

These pigments play crucial roles in various biological processes. In plants, they act as accessory pigments in photosynthesis, capturing light energy that chlorophyll cannot absorb. They also protect plants from photooxidative damage. In animals, including humans, carotenoids serve as important antioxidants. They can scavenge free radicals, thereby reducing oxidative stress and potentially lowering the risk of certain chronic diseases.

Many carotenoids are precursors to vitamin A, meaning they can be converted into vitamin A in the body. Vitamin A is essential for vision, immune function, and cell growth. Foods rich in carotenoids include colorful fruits and vegetables such as carrots, sweet potatoes, spinach, kale, tomatoes, and apricots. The body's ability to absorb and convert carotenoids can vary depending on factors like cooking methods and the presence of dietary fats.
