WebA chirality center (chiral center) is a type of stereocenter. A chirality center is defined as an atom holding a set of four different ligands (atoms or groups of atoms) in a spatial arrangement which is non-superposable on its mirror image. Chirality centers must be sp 3 hybridized, meaning that a chirality center can only have single bonds. WebAboutTranscript. Amino acids are the building blocks of proteins. They contain an amino group, carboxylic acid group, alpha carbon, and side chain. Most amino acids have a chiral carbon, which allows them to rotate polarized light. Amino acids can have either an L- or D- configuration, but only the L- form is found in the human body. grandesheroes.com.ar
