WebHydrogen bonds contribute to the stability of ion pairs with e.g. protonated ammonium ions, and with anions is formed by deprotonation as in the case of carboxylate, phosphate etc; then the association constants depend on … WebThe hydroxyl group of tyrosine can form hydrogen bonds, and it acts as an important functional group in the activity of some enzymes. Tyrosine and tryptophan are …

Tyrosine hydrogen bonds make a large contribution to protein stability ...

WebAt pH 7, tyrosine is protonated and the OH group should be able to be a hydrogen bond donor. There may be something else in the passage making lysine more correct. 4 iamfromjobland • 1 yr. ago Thanks for the response. I think I got it now. I was focused on the H-bond portion that I didn't see the amino group in the answer explanation. WebThe present FTIR data show an unusually low O–H stretching vibration of tyrosine at 2800–2600 cm–1. This provides direct evidence of the light-induced switch of the hydrogen-bonding network, where the conserved Tyr (Tyr21 for AppA) donates an unusually strong hydrogen bond in the intermediate. bone cancer in shoulder symptoms
