Carotenoids are naturally synthesized by cyanobacteria, algae, plants, some fungi, and some bacteria, but not made by … The importance of carotenoids in human nutrition is due to their health effects, varying from optical enhancement, antioxidant functions and is reported to fight noncommunicable diseases [4,5]. Fruit and vegetables provide most of the 40 to 50 carotenoids found in the human diet. Carotenoids in fruits and vegetables can be classified as: 1) hydrocarbon carotenoids or carotenes, 2) monohydroxycarotenoids, 3) dihydroxycarotenoids, 4) carotenol acyl esters, and 5) carotenoid epoxides. Carotenoids are naturally occurring pigments found in most fruits and vegetables, plants, algae, and photosynthetic bacteria. Carotenoids: Actual knowledge on food sources, intakes, stability and bioavailability and their protective role in humans.

When eaten by people, some carotenoids are converted into vitamin A, a nutrient essential for the health of the body.Certain carotenoids are converted more efficiently than others, while an entire set of carotenoids are not converted into vitamin A at all and instead operate as antioxidants. Giovina Catasta. | The oxygen can be present in the form of a hydroxy, epoxy, or keto group. The difference between the two groups is chemical: xanthophylls contain oxygen, while carotenes are hydrocarbons and do not contain oxygen. The Journal of Nutrition, Vol. human nutrition: Adulthood.

Food sources of these compounds include a variety of fruits and vegetables, although the primary sources of lycopene are tomato and tomato products. Among these classes, only carotenes, monohydroxy- and dihydroxycarotenoids are found in the human serum/plasma and milk [1, 2]. The morphology of chromoplasts and the physical deposition form of carotenoids were hypothesised to play a major role in the differences observed in the bioavailability of carotenoids from the foods investigated. 2013 May;141(5):256-61. doi: 10.1254/fpj.141.256.
