What makes an orange the color orange?

Oranges are not always orange. Some varieties are green, red, or even purple. The orange color of most oranges is due to the presence of carotenoids, specifically beta-carotene. Carotenoids are pigments that are found in many plants and animals. They are responsible for the bright colors of many fruits and vegetables, such as carrots, pumpkins, and sweet potatoes.

Beta-carotene is a precursor to vitamin A. It is converted to vitamin A in the liver. Vitamin A is important for vision, skin health, and immune function.

Oranges also contain other carotenoids, such as lutein and zeaxanthin. These carotenoids are important for eye health. They help to protect the retina from damage caused by ultraviolet light.

The amount of carotenoids in an orange depends on the variety of orange and the growing conditions. Oranges grown in warm, sunny climates tend to have more carotenoids than oranges grown in cooler climates.

Oranges are a good source of vitamin C, potassium, and fiber. They are also a good source of antioxidants, which help to protect the body from damage caused by free radicals.
