The amino acid was synthesized as a racemate and two diastereomeric peptides were obtained. Scientists capture the misfolding of rogue proteins in action from indiabioscience.org In addition to the alpha helix and beta sheet secondary structures (see bio 13 tutorials), another distinct structural motif has been recognized in which the the polypeptide. Beta turns, also known as beta bends or tight turns, are a type of secondary structure.
