Definition of carotene in English English dictionary
Specifically, a number of isomers of tetraterpene hydrocarbons, C40H56, (especially beta-carotene), present in carrots etc, which are converted into vitamin A in the liver
A class of tetraterpene plant pigments; they vary in colour from yellow, through orange to red, this colour originating in a chain of alternating single and double bonds
Specifically, a number of isomers of tetraterpene hydrocarbons, C{40}H{56}, (especially beta-carotene), present in carrots etc, which are converted into vitamin A in the liver
Carotene is an unsaturated hydrocarbon pigment found in many plants Carotene is the basic building block of vitamin A
A class of carotenoids Some carotenes, including alpha-, beta-, gamma- and zeta-carotene, have some pro-vitamin A activity Others, such as lycopene, do not Most carotenes are found in yellow-orange fruits and vegetables such as apricots, mangoes, carrots and sweet potatoes Alpha- and beta-carotene have both been linked to reduced risk of lung cancer Beta-carotene has also been shown to support heart health
an orange isomer of an unsaturated hydrocarbon found in many plants; is converted into vitamin A in the liver
Any of several organic compounds widely distributed in plants and animals. They are pigments that give orange, yellow, or sometimes red colours to, for example, dandelions, apricots, carrots, sweet potatoes, butter, egg yolks, canary feathers, and lobster shells. Carotenes are converted in the body into vitamin A, but, unlike the vitamin, they are not toxic even at high doses. Carotene has an antioxidant effect and is therefore used in pharmaceuticals and as a food and feed additive, as well as to colour margarine and butter
converted to vitamin A in the body derived from a yellow pigment that has several forms (i e alpha-, beta-)
an orange-yellow pigment occurring in many plants and capable of being converted into vitamin A in the body
One of the simplest member of the carotenoid family of natural dyes It is a polyene with 22 conjugated methine groups terminated on each end by a -ionone group
a reddish-orange antioxidant pigment found in dark yellow or orange fruits and vegetables Beta carotene is a precursor of Vitamin A that is stored in the liver and converted as needed
(Vitamin A) - Cell differentiation, bone growth, immunity, tooth development, reproduction, healthy skin, hair, mucous membranes and vision A fat-soluble vitamin needed for the normal functioning of the eyes It also helps the body resist infection, keeps skin cells moist, and is important in the functioning of the nervous, reproductive and respiratory systems The best natural sources are liver-especially fish liver and fish-liver oils-whole milk, cheese and eggs Vitamin A does not exist in plants However, leafy green and yellow vegetables and yellow fruits contain a pigment called carotene, which the liver can convert into Vitamin A Among the best sources of carotene are dandelion and turnip greens, carrots, collards, cantaloupe, sweet potatoes and apricots
a fat-soluble pigment the body uses to make Vitamin A; it can also meet daily requirements for Vitamin A without the accompanying toxic changes caused by large doses of Vitamin A Beta carotene, the most abundant of several forms of carotene (also alpha- and gamma-), enhances immunity and acts as an antioxidant Relatively non-toxic, though some research suggests that combining it with high amounts of alcohol may result in liver damage Current research focuses on beta carotene and cancer Food products containing large amounts of Vitamin A should indicate whether the Vitamin A activity is from Vitamin A or beta-carotene Vitamin A activity is expressed as retinol equivalents (RE); one RE equals 6 g of beta-carotene
The precursor of vitamin A Supplementation with beta-carotene may improve reproductive performance, although it is generally considered to be economically infeasible
A phytonutrient carotenoid with antioxidant and provitamin A activity In addition to providing the body with a safe source of Vitamin A, beta carotene works with other natural protectors to defend your cells from harmful free radical damage This is an important micrinutrient in helping the body with metabolic functions, such as recovery from exercise
A nontoxic plant derivative of vitamin A that the body converts to vitamin A and which, as an antioxidant, is widely accepted as a cancer preventive Rich sources are yellow and orange fruits, vegetables such as papaya and carrot, and green leafy vegetables
- A type of carotene (see carotenoids) that is a pre-cursor to Vitamin A Beta-carotene has been the most studied of all the carotenes and is known for its antioxidant protective benefits Beta-carotene is a flavonoid that gives apricots, carrots, peaches and sweet potatoes their color
The carotenoid in tomatoes with the most vitamin A activity It also has ANTIOXIDANT activity Once thought to be a major player in cancer prevention, recent scientific studies show less encouraging results, possibly because beta-carotene was studied alone rather than in association with other vitamins and antioxidants
