Detailed explanation-1: -Golden rice is genetically modified to produce beta-carotene, which is not normally present in rice. Beta-carotene is converted into vitamin A when metabolized by the human body.
Detailed explanation-2: -Golden Rice is a new type of rice that contains beta carotene (provitamin A, a plant pigment that the body converts into vitamin A as needed). This compound is what gives this grain its yellow-orange or golden color, hence its name. Golden Rice is developed through genetic engineering.
Detailed explanation-3: -This transgenic, or genetically modified, rice produces beta-carotene, a precursor to vitamin A, in the normally white endosperm (8) and has proven an effective source of vitamin A in humans (9).
Detailed explanation-4: -Conclusion: Beta-carotene derived from Golden Rice is effectively converted to vitamin A in humans.
