Although several tertiary structure models of PHA synthases have been and mono- and oligosaccharides coupled to carrier molecules, can be stably It is important to conceptually understand the functions of these bioinformatics tools This explains why a molecule of R-carvone can have a smell of mint green These two forms are called enantiomers (Greek enantios. "opposite").

Concept: General properties of hydrohalogenation. Example: Provide the mechanism of the following addition reaction. Problem: Which of the molecules below are enantiomers formed as products upon reaction of HBr with 4-methylpent-1-ene?A. I and IIB.
Enantiomers are a pair of molecules that exist in two forms that are mirror images of one another but cannot be superimposed one upon the other.
Just like how our hands are mirror images of each other, molecules can also have mirror images that cannot be superimposed on each other. These molecules are called enantiomers.
If a pair of stereoisomers are non-superimposable mirror images of each other, then they are enantiomers.
A strategy, which is based on the Latin terms for left (sinister) and right (rectus), has been developed for distinguishing between a pair of enantiomers.Arrange the four substituents in order of decreasing atomic number of the atoms attached to the stereocenter.
