WebA chiral carbon, (also known as an asymmetric carbon) is a carbon atom which has 4 different atoms or groups of atoms attached to it. For each chiral carbon in a molecule there are 2 optical isomers . This increases exponentially with more chiral carbons, so a molecule with 2 chiral centers would have 4 optical isomers, and a molecule with 3 ... WebSep 30, 2024 · Helicenes are interesting chiral molecules without asymmetric carbon atoms but with intrinsic chirality. Functionalized 5-Aza[5]helicenes can form non-covalent complexes with anticancer drugs and therefore be potential carriers.

WebAn amino acid has the general formula H₂N-CH (R)-COOH, where R stands for the different acids. Notice that the central C atom is chiral — it has four different groups attached — so the molecule can exist as a pair of enantiomers (nonsuperimposable mirror images). One of these is the D isomer, and the other is L (i.e. a pair of R/S isomers). WebThe helical structure of carbon nanotubes is described by the chiral vector, C = n a 1 + m a 2, represented by (n, m), where n and m are integers and a 1 and a 2 are non-orthogonal basis vectors. There are three basic types of carbon nanotubes depending on the chiral vector, and these are armchair m = n, zigzag m = 0 and chiral with 0 < m < n.
