2、體系以及磷脂/正丙醇/異辛烷/水o/w微乳體系均為穩(wěn)定的磷脂酰膽堿微乳體系。3種微乳體系和脂質(zhì)體分別與鴨肉肌內(nèi)磷脂酶振蕩反應(yīng)10h后,采用TLC聯(lián)用QuantityOne軟件鑒定反應(yīng)產(chǎn)物中的脂肪酸,以脂肪酸斑點(diǎn)分析的TraceQty值為指標(biāo),最終確定磷脂酰膽堿反應(yīng)體系。因此,以脂質(zhì)體作為反應(yīng)體系所產(chǎn)生的脂肪酸最多,即脂質(zhì)體為磷脂酰膽堿最佳反應(yīng)體系。為進(jìn)一步研究磷脂酰膽堿的酶解機(jī)制和磷脂酶的分離純化提供技術(shù)方法。關(guān)鍵詞:磷脂酰膽堿;磷脂酶;微乳;脂質(zhì)體中圖分類號(hào):S858.3文獻(xiàn)標(biāo)識(shí)碼:AEstablishingReactionSystemofPhosphatidylcholineB1
