Description
本研究將大幅改善高解析質譜(HRMS)的體學分析策略,搭配我們最新建立的質譜數據後處理軟體FeatureHunter,以迅速篩檢HRMS分析輸出的羰基體學及DNA/RNA/Protein 鍵結體學的原始數據。同時,引入穩定同位素標記衍生及穩定同位素標定質譜技術,建立新穎非標靶多體學的整合分析平台,以期:(1)由食用油中主要脂肪酸的占比來預測食用油加熱後各種醛酮的生成變化及特徵;(2)探討食入高溫氧化食用油(脂肪酸)的醛酮暴露與效應生物標記。本研究將可提出食用油使用建議(如參考主要脂肪酸含量採用合適的溫度烹飪),降低醛酮的暴露,並提出評估醛酮暴露及鍵結DNA/RNA/Protein的新生物標記。
