Unlike traditional "wet" analytical methods which during processing for analysis often result in destruction or alteration of the intrinsic protein structures, advanced synchrotron radiation-based Fourier transform infrared microspectroscopy has been developed as a rapid and nondestructive and bioanalytical technique. This cutting-edge synchrotron-based bioanalytical technology, taking advantages of synchrotron light brightness (million times brighter than sun), is capable of exploring the molecular chemistry or structure of a biological tissue without destruction inherent structures at ultra-spatial resolutions. In this article, a novel approach is introduced to show the potential of the advanced synchrotron-based analytical technology, which can be used to study plant-based food or feed protein molecular structure in relation to nutrient utilization and availability. Recent progress was reported on using synchrotron-based bioanalytical technique synchrotron radiation-based Fourier transform infrared microspectroscopy and diffused reflectance infrared Fourier transform spectroscopy to detect the effects of gene-transformation (Application 1), autoclaving (Application 2), and bio-ethanol processing (Application 3) on plant-based food and feed protein structure changes on a molecular basis. The synchrotron-based technology provides a new approach for plant-based protein structure research at ultra-spatial resolutions at cellular and molecular levels.
与传统的“湿”分析方法不同,这些方法在分析过程中往往会导致蛋白质结构的破坏或改变,而先进的基于同步辐射的傅里叶变换红外显微镜技术已经发展成为一种快速、无损和生物分析技术。这种基于同步加速器的尖端生物分析技术利用同步加速器光的亮度(比太阳亮百万倍),能够在不破坏固有结构的情况下,以超空间分辨率探索生物组织的分子化学或结构。本文介绍了一种新方法,展示了先进的基于同步加速器的分析技术的潜力,该技术可用于研究植物性食品或饲料蛋白质的分子结构与营养利用和可用性的关系。本文报道了利用基于同步加速器的生物分析技术(应用 1、应用 2 和应用 3)研究基因转化、高压灭菌和生物乙醇加工对植物性食品和饲料蛋白质结构变化的影响的最新进展。基于同步加速器的技术为在细胞和分子水平上进行超空间分辨率的植物性蛋白质结构研究提供了一种新方法。
