but different chemical structure. Enantiomers often have similar chemical properties, but differ in how they rotate polarized light and how they interact with other chiral molecules. There are a wide variety of chiral molecules in biology, and as a result, chirality is essential to many pharmacologi...

(in which case the sample is a collection of homochiral molecules) to equal representation by molecules and their mirror-image isomers (in which case the sample is heterochiral or racemic), or any distribution inbetween (heterochiral and nonracemic). Extended tetrahedra (see bottom of Figure 3)...
Asymmetric carbon atoms are named as such because they are asymmetrical, or the opposite of symmetrical. Asymmetrical molecules cannot be divided in half to produce two mirror images. Another name for an asymmetric carbon is chiral carbon. Chiral molecules are asymmetric and typically exist in ...
3. Chiral Molecules So far, we’ve covered diastereotopic protons found in achiral molecules, but the same type of protons can be found in molecules containing a chiral center, too. Let’s take a look at the example below. 2-butanone produces 3 signals in a 1H spectrum, while 2-butanol...

Which elements form diatomic molecules? Diatomic molecules are made up of only two atoms of the same or different elements that are chemically bonded together. There are many diatomic molecules, but each one will only consist of two atoms. Elements can form homonuclear diatomic molecules where ...
Ketohexoses have three chiral centers. As such, there are eight possible stereoisomers. Examples of ketohexoses are fructose, piscose, sorbose, and tagatose. Word origin:hex(a)– (“six”) + –ose” (relating tosugars) See also:
Optical purity is typically a characteristic of chiral electrophiles. The fructose-derived organocatalyst used in Shi epoxidation is one such reagent. The catalyst will epoxidate trans-disubstituted and trisubstituted alkenes with high enantioselectivity. Until continuing in the catalytic cycle, the Shi ...
Because monomers represent a huge class of molecules, they are commonly categorized into various subgroups such as sugars, alcohols, amines, acrylics, and epoxides. The term "monomer" combines the prefixmono-, which means "one," and the suffix-mer, which means "part." ...
