By directly monitoring stirred protein solutions with Raman spectroscopy, the reversible unfolding of proteins caused by fluid shear is examined for several natural proteins with varying structural properties and molecular weight. While complete denaturation is not observed. a wide range of spectral variances occur for the different proteins, indicating subtle conformational changes that appear to be protein-specific A number of significant overall trends are apparent from the study For globular proteins, the overall extent of spectral variance increases with protein size and the proportion of beta-structure For two less structured proteins, fetuin and a-casein. the observed changes are of relatively low magnitude, despite the greater molecular structural mobility of these proteins This implies that other protein-specific factors, such as posttranslational modifications, may also be significant Individual band changes occurring in the spectral profiles of each individual protein are also discussed in detail
