Guest guest Posted October 16, 2007 Report Share Posted October 16, 2007 Speaking of science, Im doing a research project in english with the topic, Were humans designed to eat meat. If anyone has any good info or links regarding evolution, creation, and raw food, i sure would appreciate the help.

Still, a good example of how we can get past the use of animal products in areas other than food.Liz____________Corny collagenBrian VastagFrom Boston, at a meeting of the American Chemical SocietySlaughterhouse leftovers such as skin, tendons, bone, andcartilage are often processed into gelatin that's used in manyproducts, including pill coatings and capsules. The primary protein ingelatin, collagen, can now be extracted from an engineered strain ofcorn, researchers report, suggesting that the pharmaceutical industrycould go vegetarian.In 2004, scientists at the company FibroGen in South SanFrancisco, Calif., spliced a collagen gene into corn and grew a smallplot of the transgenic crop in Nebraska. But it took until now todevelop a four-step procedure to recover and purify the small amountsof collagen in the corn, reports Iowa State University's Cheng Zhang,part of the team that collaborated with FibroGen to develop theprocess.Unlike its animal–by-product cousin, the corn-derived collagenpurified at Iowa State in Ames is uniform in composition and should beeasier for drugmakers to work with, says FibroGen's Julio Baez. It alsoeliminates the danger of transferring animal viruses to people via theslaughterhouse product."Right now there are 1,000 cows in every cold capsule," Baezquips. After collagen extraction, corn waste could serve as a rawmaterial for making ethanol or other products, he says (SN: 8/25/07, p. 120).His team is now trying to boost the yield of corny collagen. Thetest crop generated just 3 milligrams of collagen per kilogram ofkernels. See what's new at AOL.com and Make AOL Your Homepage. Quote Link to comment Share on other sites More sharing options...
