Example sentences for: deprotonation

How can you use “deprotonation” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • The L → M transition in bR is characterized by the deprotonation of the Schiff base to Asp-85, producing the distinctive 412 nm absorbance maximum of M, and by so-called fast proton release, the ejection of a proton from a different (unknown) residue into the external medium on the ~10-100 μs time scale, depending on pH.

  • This would be consistent with a proposed mechanism for fast H +release that has been observed above pH 10 in the bR mutant E194Q [ 14 ] . In this mutant, Asp-85 was detected by low-temperature infrared difference spectroscopy to be deprotonated only in the N intermediate, and not in M [ 15 ] . It is not clear yet whether Asp-85 deprotonation in an N-like state could account for the proton-release kinetics of pR (Fig.

  • The Schiff base readily undergoes deprotonation in the M intermediate.

  • Deprotonation of the Schiff base linkage of the retinal and Lys-216 is dependent on its pK a which changes between photointermediate states.
