Racemic crystal
Racemic crystallography is a technique used in structural biology where crystals of a protein molecule are developed from an equimolar mixture of an L-protein molecule of natural chirality and its D-protein mirror image. L-protein molecules consist of 'left-handed' L-amino acids and the achiral amino acid glycine, … See more Native chemical ligation of unprotected peptide segments is used to prepare the protein's polypeptide chain, which is then folded to form a protein molecule. In native chemical ligation a peptide C-terminal thioester … See more There are just 230 different ways of arranging objects in regular three-dimensional arrays. In molecular crystallography, these arrangements are called 'space … See more History In 1989, Alan Mackay suggested that if chemical synthesis could be used to make L-protein and D-protein enantiomers, it would enable the … See more
