α-carotene
IUPAC 名称
(6E)-1,5,5-trimethyl-6-[(2E,4E,6E,8E,10E,12E,14E,16E)-3,7,12,16-tetramethyl-18-[(1E)-2,2,6-trimethylcyclohexylidene]octadeca-2,4,6,8,10,12,14,16-octaen-1-ylidene]cyclohex-1-ene
描述
α-carotene can be found in a number of food items such as cumin, mountain yam, pineappple sage, and red rice, which makes α-carotene a potential biomarker for the consumption of these food products. Carotenes are responsible for the orange colour of the carrot, for which this class of chemicals is named, and for the colours of many other fruits, vegetables and fungi (for example, sweet potatoes, chanterelle and orange cantaloupe melon). Carotenes are also responsible for the orange (but not all of the yellow) colours in dry foliage. They also (in lower concentrations) impart the yellow coloration to milk-fat and butter. Omnivorous animal species which are relatively poor converters of coloured dietary carotenoids to colourless retinoids have yellowed-coloured body fat, as a result of the carotenoid retention from the vegetable portion of their diet. The typical yellow-coloured fat of humans and chickens is a result of fat storage of carotenes from their diets .
