Carotenoid Meaning: Definition, Examples, and Translations
🥕
carotenoid
[ˌkærəˈtoʊɪd ]
Definition
biochemistry, pigments
Carotenoids are pigments found in the chloroplasts and chromoplasts of plants and some other photosynthetic organisms. They are responsible for the red, orange, and yellow colors of many fruits and vegetables and play essential roles in photosynthesis and photoprotection. In addition to their color, carotenoids are important for human health as they can be converted into vitamin A and have antioxidant properties.
Synonyms
colorant, pigment, plant pigment.
Examples of usage
- Carrots are high in carotenoids, giving them their orange color.
- The bright hues of autumn leaves are due to the accumulation of carotenoids.
- Spinach and kale are rich in carotenoids, which provide health benefits.
- Carotenoids in tomatoes improve their nutritional value.
- Pumpkins are a great source of carotenoids, especially beta-carotene.

Origin of 'carotenoid'
Main points about word origin
- The word comes from 'carota', the Latin word for carrot, highlighting the pigment's bright orange color.
- The suffix '-oid' means 'like' or 'resembling', so carotenoids are 'like carrots' in color.
- First introduced in the late 19th century, carotenoids were identified as plant pigments that appeal to both humans and animals.
The term 'carotenoid' originates from the Latin word 'carota', meaning carrot, as these compounds were first discovered in carrots. It was coined in the early 20th century, around the 1930s, as scientists began to identify and study these important pigments. Carotenoids are a class of terpenoids, which are organic compounds produced by various plants; they are derived from the isoprene unit. Over time, the understanding of carotenoids has expanded significantly, revealing just how crucial they are not only for plants, but also for human nutrition and health. Their antioxidant properties contribute to the prevention of chronic diseases, making carotenoids a subject of interest in both nutrition and food science.
