摘 要: 小麦胚芽8S球蛋白是其球蛋白最主要的成分,深入了解小麦胚芽8S球蛋白的相关信息将有助于促进小麦胚芽资源的深度开发和利用。主要采用傅里叶变换红外光谱(Fourier transform infrared spectroscopy, FTIR)研究小麦胚芽8S球蛋白的二级结构。研究结果表明:小麦胚芽8S球蛋白的二级结构主要为β折叠(53.8%),另外还含有α螺旋(23.5%)和无规卷曲(22.7%)2种构象。
关 键 词: 食品加工的副产品加工与利用;小麦胚芽8S球蛋白;傅里叶变换红外光谱;二级结构

Abstract: Wheat germ 8S globulin was the major fraction of wheat germ globulin, hence it is necessary to deeply understand some information about wheat germ 8S globulin to promote it development and utilization. In this paper, Fourier transform infrared spectroscopy (FTIR) spectrometer was adopted to study the secondary structure of wheat germ 8S globulin. The results of experiments showed that 8S globulin was a protein rich in β sheet structure (53.8%), followed by α helical (23.5%) and random coil structure (22.7%).
Key words: processing and utilization of by-products from food processing; wheat germ 8S globulin; Fourier transform infrared spectroscopy; secondary structure
