The influence of TF1 on the structure of bovine serum albumin (BSA), β-lactoglobulin (β-Lg), and α-lactoalbumin (α-La) was examined in this work using the … Webα Helix and β Sheet There are several structural features of polypeptides that define the overall shape of proteins. Figure 8.5 describes two major fundamental structural motifs of protein structure: the α helix and the β sheet. In addition to these well-defined structures, regions of a polypeptide can exist in an unordered configuration.
