= Stereocenter
{wiki}

At a <stereocenter>, exchanging two attached groups produces a different spatial configuration. The open-chain <ribose> and <glucose> examples have <carbon> <stereocenters> bearing four different groups; C2 of <deoxyribose> has two identical <hydrogen> substituents and is not a <stereocenter>. See https://iupac.qmul.ac.uk/stereo/RS.html#stereogenic[Moss, Basic Terminology of Stereochemistry, IUPAC Recommendations 1996: stereogenic units].
