Two enantiomers of a generic amino acid at the stereocenter. In stereochemistry, a stereocenter of a molecule is an atom (center), axis or plane that is the focus of stereoisomerism; that is, when having at least three different groups bound to the stereocenter, interchanging any two different groups creates a new stereoisomer.
Enantiotopic groups are identical and indistinguishable except in chiral environments. For instance, the CH 2 hydrogens in ethanol (CH 3 CH 2 OH) are normally enantiotopic, but can be made different (diastereotopic) if combined with a chiral center, for instance by conversion to an ester of a chiral carboxylic acid such as lactic acid, or if coordinated to a chiral metal center, or if ...
The attachment studies programme at University of Roehampton, U.K., includes the DMM and some of its assessments, as does the Barnard Center for Infant Mental Health and Development at the University of Washington in Seattle. [citation needed] IASA maintains a list of publications describing the DMM. [35] There are over 500 such publications.

Hence, they occur when two or more stereoisomers of a compound have different configurations at one or more (but not all) of the equivalent (related) stereocenters and are not mirror images of each other. [2] When two diastereoisomers differ from each other at only one stereocenter, they are epimers. Each stereocenter gives rise to two ...
Attachment measures, or attachment assessments, are procedures used to assess the attachment system in children and adults. These procedures can assess patterns of attachment and individual self-protective strategies. Some assessments work across the several models of attachment and some are model-specific.

The isopropenyl group has priority 1 (carbon atoms only), and for the two remaining carbon atoms, priority is decided with the carbon atoms two bonds removed from the stereocenter, one part of the keto group (O, O, C, priority number 2) and one part of an alkene (C, C, H, priority number 3).
