The carotenoids belong to the isoprenoids and their basic structure is made up of eight isoprene units, resulting in a C40 backbone. Formally, two types of carotenoids can be discerned: Carotenes are pure hydrocarbons while xanthophylls are derivatives that contain one or more oxygen functions. ...
colorata and made up > 40% of total carotenoids. Traditional preparation and processing procedures led to significant losses of carotenoids and β-carotene was most affected during sun-drying with a maximum of 73.8% loss observed in A. acanthochiton....
They are biosynthesised by a specialised branch of the isoprenoid or terpenoid pathway which is also used for the biosynthesis of a wide variety of other important compounds. All isoprenoid compounds are built up from the C 5 "isoprene unit" the carbon skeleton of which is clearly seen in ...
In foodstuffs, carotenoids not only confer various degrees of coloration (yellow, orange, or red) but also serve as precursors of aroma compounds; they may help extend shelf life because of their antioxidative activity. Furthermore, carotenoids play effective roles inside the human body. They can ...
Even though some studies have been made to understand relationship between structure of carotenoids and their anticancer effect, still there is a lack of knowledge on how carotenoids are transferred and modified into apo-carotenoids in the cell45,46. Nevertheless, it is known that com- plex ...
The proportion of the original carotenoid dose that ends up in the micelle is known as the “bioaccessible” fraction, which is the only proportion of the original dose thought to be available for absorption [54]. The type of lipid co-consumed strongly influences bioaccessibility, with long-...
Sweetpotato also offers notable nutritional and health benefits, owing to its rich content of essential vitamins, minerals, and antioxidants. Of particular interest is β-carotene, a precursor of vitamin A, abundant in orange-fleshed sweetpotato varieties. A vital nutrient for human health, β-...

2 Carotenoids as tetraterpenoids are simple or pure prenyl lipids, the carbon skeleton of which is made up solely of isoprenoid units. Chlorophyll a and b are mixed prenyllipids: they possess an isopre- noid phytyl chain which is bound to a nonisoprenoid porphyfin ring sys- tem. The ...
