H2O can act as both a proton donor and acceptor for itself.

Addition of water or another proton donor gives the diol.

In these cases, triflic acid is a typical proton donor.

He also came up with the highly used theory of the proton donor along with Lowry.

Each proton donor enhanced catalytic activity in a saturable manner.

Evolutionary, thermodynamic and molecular modeling evidence predicted Tyr-48 as the proton donor.

The two aspartic acids mentioned above act as proton donors and acceptors.

He explains, for example, that hydrochloric acid should be seen not as a proton donor, but an electron thief.

The proton donor interacts with a terminal hydride of 2 forming a rather strong hydrogen bond.

N-methylacetamide was found to be a better proton donor than N-methylformamide in disagreement with theoretical predictions.

A Brønsted-Lowry acid is a proton donor, not an electron-pair acceptor.

Acid and bases are referred to as proton donors and acceptors correspondingly.

For a given amidine, the dipole increment increases when the proton donor becomes more acidic.

The acid is the proton donor and the base is the proton acceptor.

Sequence alignment indicates that there are five highly conserved acidic residues, one of which might act as a proton donor.

They defined acids as proton donors and bases as proton acceptors.

Carboxylic acids are Brønsted-Lowry acid-base theory - they are proton donors.

The sulfhydryl group (SH) of cysteine serves as a proton donor and is responsible for its biological activity.

The lysine holds the sugar in place while the glutamate and aspartate act as proton donors and acceptors.

The results permit a comparison between the proton donating abilities of these compounds. It is possible to classify them against other well-known proton donors.

A hydroxyl group serves as a bridging ligand but also functions as a proton donor to the O substrate.

The Brønsted-Lowry definition is an expansion to include solvents other than water: an acid is a substance which can act as a proton donor.

In this experiment, ethanol acts both as a solvent of benzophenone and a proton donor for the alkoxide, completing the formation of the alcohol.

Under the Bronsted-Lowry theory, acids are proton donors, while bases are proton acceptors.

Later in the pathway, His263 is used as a proton donor for the substrate acceptor-TPP complex, which can then generate erythrose-4-phosphate.
