用“stereochemistry”造句大全，stereochemistry造句

The progress of the optical activity and stereochemistry of bile pigments in recent20 years is reviewed.

Structural formulas show bonds (see bonding) between atoms in a molecule as short lines between symbols; they are particularly useful for showing how isomers differ. A projection formula also indicates the three-dimensional arrangement of the atoms (see Fischer projection; stereochemistry).

In this paper some uncoventional reaction of aldehyde and ketone with grignard reagent and the question of stereochemistry in the reaction was stueied chiefly.

The relative stereochemistry of the 1, 10-double bond and that of the methoxyl, methyl, and acetoxy groups were determined by NOESY experiments and analyses of the coupling constants.
