Indawo inkulu kwikhemistri yi-polymer khemistri. Le ke ijongana nee-plastics. Umzekelo omnye kukwenza i-nylon. kuba ii-plastics zenziwe ngee-carbon, i-polymer khemistri yinxalenye ye-organic chemistry. Esinye isifundo sese-biochemistry. esi sifundo siqwalasela ikhemistri yezinto ezinobomi. Umzekelo ngowaxa unokubona okokuba i-arsenic iyityhefu njani ebantwini. I-Biochemistry nayo ikwayinxalenye ye-organic khemistri. akho namanye amasebe amaninzi e-khemistri.
