Similarly, oxygen associates with silver and reacts with the sulfhydryl (−S-H) groups on cell wall to remove the hydrogen atoms (as water), causing the sulfur atoms to form an R-S-S-R bond, blocked the respiration, and causing the lethal effect of bacterial cells [39].
For example, we determined a broad linear correlation of the bridging P O(R) bond length in monosubstituted dianionic phosphates and the p Ka of the substituent alcohol.
We addressed the relationship between ground-state bonding properties and reactivity and found that a change of just 0.02 Å of the bridging P O(R) bond length is quantitatively correlated to orders of magnitude in change to reactivity.
Ring bonds and non-single bonds are generally regarded as rigid.
The activating cleavage in plasminogen occurs between the R-V bond, while in PAI-1 and probably also in α2AP the cleavage occurs between R-M in the reactive center loop.
An arc i R j R covers a bond l R ○ k S if i R < l R < j R. We call i R j R an interaction arc if there is a bond l R ○ k S covered by i R j R. A kissing arc is an interaction arc that directly covers a bond.
Sialic acid residues are known to be linked via an R-2,3 or an R-2,6 bond to Gal/GalNAc in proteins.
Red arrows: H-bonds, red star: negative ionizable feature, yellow spheres: hydrophobic contacts.
Ring Double Bond Equivalence.
Alexander (R-TN) - two daughters Barrasso (R-WY) - two daughters Bond (R-MO) - no daughter Brownback (R-KS) - three daughters Bunning (R-KY) - five daughters Burr (R-NC) - no daughter Chambliss (R-GA) - one daughter Coburn (R-OK) - three daughters Cochran (R-MS) - ?
Using the sum of the cation radii, r, as a measure of the sizes of the cores, the space occupied by the bonding electrons is (R − r), 3) where R is the bond length.
