Sentence examples for bond at the D-ring from inspiring English sources

Cleavage of C-O bond at the D-ring and reorganization of the D-ring renders the tasteless limonoate A-ring lactone that can be alternatively glycosylated (as occurs during normal maturation) or converted into bitter limonin [ 17].

The simulation revealed hPR Cys891 as the sole but weak hydrogen bonding partner of progesterone in the D-ring.

Hydroxylation at the 16α position of the D-ring produces 16-pathway metabolites [ 8].

While unexpected, this behavior of E4 may be a consequence of an efficient intramolecular network of hydrogen bonds, operating among the three OH groups in the D-ring that in some way effectively suppresses their polar nature, thus allowing the D-ring to reside more comfortably in the hydrophobic core of the bilayer.

The carbonyl oxygen atom (close to E ring) of the D-ring was stabilized by a hydrogen bonding interaction with the side chain amide group of Gln725 (-CO H2NOC-Gln725).

Two more hydrogen bonds are formed by the D ring with a backbone amide of the P-loop and the side chain of Glu239 (Table 1).

This orientation is rather counterintuitive, although an efficient intramolecular network of hydrogen bonds among the three D-ring OH groups might be masking their polarity more effectively than the lone 17β-OH in E2.
