Most inorganic acids are also weak but a few are strong. Inorganic acids can also be called mineral acids.
Alpha amino acids have the -COOH and -NH2 groups both attached to the same carbon atom, called the alpha carbon atom. The simplest amino acid, which is the molecule glycine, H2NCH2COOH, contains no asymmetric carbon atoms (tetrahedral carbon atoms with four different groups attached). All of the other amino acids do contain such a carbon atom and are therefore optically active.
