Plant oils are very important for domestic and industrial use. Biodiesel can be obtained from plant seed oil. Biodiesel is currently popular and in demand due to the high cost of petroleum and to avoid pollution. It is time to increase plant seed oil production and conduct research to find ways of enhancing its production. We studied two species of oil seed plants, . Ricinus communis and Glycine max, with varying amounts of oil content. Proteins from six categories of enzymes involved in fatty acid biosynthesis were selected for study. The 3D structures were predicted using different structure prediction tools. The structures were validated and selected on the basis of quality factors. |
