Sentence examples for bond at the position from inspiring English sources

This reaction forms an ester bond at the C2' position of paclitaxel.

In addition the ozonolysis experiments show that the C18 acyl group has a double bond at the position shown, but it does not establish whether it is cis or trans.

Both enzymes catalyze the same kind of reaction, cleaving the C-C bond at the C-3' position forming the furanocoumarin skeleton and acetone in equimolar amounts [ 15, 16].

Anecortave acetate differs in structure from cortisol by the removal of 11-beta hydroxyl, addition of a double bond at the C9-11 position, and addition of an acetate group at the C21 position to enhance bioavailability.

This elimination would create a double bond at the C2 C3 position of the glucosamine, which further set the stage for the elimination (peeling) at the C-4 position as the C-2 -NH- group gets deprotonated at basic conditions (Scheme 2A).
