WebStereochemistry focuses on stereoisomers. In stereochemistry, stereoisomerism, or spatial isomerism, is a form of isomerism in which molecules have the same molecular formula and sequence of bonded atoms (constitution), but differ in the three-dimensional orientations of their atoms in space. [1] [2] This contrasts with structural isomers ... WebEpimers are diastereomers that differ at one chiral center. That's a vocab word that's probably going to come up several more times as you look at carbohydrate chemistry. You can this thought of D verse L carbohydrates to the next level with critical thinking if you consider all of the stereoisomers for an aldohexose.

All of the known life-forms show specific chiral properties in chemical structures as well as macroscopic anatomy, development and behavior. In any specific organism or evolutionarily related set thereof, individual compounds, organs, or behavior are found in the same single enantiomorphic form. Deviation (having the opposite form) could be found in a small number of chemical compounds, … WebAn amino acid has the general formula H₂N-CH (R)-COOH, where R stands for the different acids. Notice that the central C atom is chiral — it has four different groups attached — …
WebChirality is the existence of different configurations of a substance with an identical chemical structure. This substance may be resolved into enantiomers with nonsuperimposable mirror images. Thus, a chemical substance having two isomers is known as a chiral compound. Chiral substances having a 50:50 mixture of the two …
