“…In this context, ecological fickerts were developed by the Centre of Mineral Technology (CETEM) [12] as an invention that aims to make the dimension stone sector follow the ecoefficiency way. These fickerts were made using polyurethane resin from castor beans (Ricinus communis L.) and presented low wear and high gloss values in a granite slab polishing test [13].…”

“…Esse modelo foi proposto porVerheij et al (1980) e mostra a interação do íon cálcio com o Asp 49 do sítio catalítico de sPLA2s e substrato. A molécula de água polarizada pelos resíduos His 48 e Asp 99 ataca o grupo carbonila do substrato (Fonte:Silveira, 2011).O íon Ca 2+ é fundamental para a estabilização das moléculas envolvidas no processo catalítico, ao se manter coordenado à carboxila da cadeia lateral do Asp 49 e aos oxigênios carbonílicos dos resíduos de Tyr 28 , Gly 30 e Gly 32 , bem como a duas moléculas de água (Figura 3). O fosfolipídeo desloca uma das moléculas de água coordenadas pelo íon cálcio, formando o complexo enzima-substrato.…”
