Genetically Modified Rice

Golden Rice and Genetically Modified Food: An canvas Daisy Pyman SCH3U1 Ms. Stoltz November.30th, 2011 Room 114 What is gold sieve? Golden sieve is a genetically engineered food created to help improve vitamin A lack. (Barry) Created in 1999 by scientists Ingo Potrykus, of the Swiss Federal Institute of Technology, and Professor catch Beyer, of the University of Freiburg, Germany. The scientists were able to produce beta-carotene in the endosperm by introducing two daffodil genes and one bacterial gene into the rice Children and adults all incisively about the world are not possessting the required check into of vitamin A to remain healthy, this results in irreversible blindness appropriate 500,000 children annually.(Ackerman) Golden rice could help to signifi enduretly alleviate Vitamin A deficiency affecting approximately 100,000,000-140,000,000 children around the world. (Ackerman) U nlike level(p) white rice (which is low in protein and has very weensy iron and virtually no vitamin A) golden rice contains beta-carotene (a carotenoid a precursor to Vitamin A) frame in the endosperm. (The edible part of the rice, the grain) outline: Carontenoid.

Carotenoids are pigments that apparent motion the red, orange, and yellow color of fruits and vegetables, found in chloroplasts and chromoplasts. (Mithra) This carotenoid, beta carotene, is a pre-cursor (a substance from which another, usually more active voice or mature substance is formed.) to Vitamin A. (Biology Online) The beta-caroten e is then reborn into Vitamin A in the huma! n body. Beta-Carotene gets broken down in the mucous membrane of the small intestine by beta-carotene to retinal. It can be stored in the liver and body fat and converted to retinal when it is needed. The existence of beta-carotene gives the genetically modified variety of rice its golden colour, hence the name, golden rice.
