Example sentences for: carbonyl
How can you use “carbonyl” in a sentence? Here are some example sentences to help you improve your vocabulary:
predicted that Phe158 and Ile 164 form hydrophobic interactions with bulky substituents on the substrate, suggesting that the loss of these residues would only affect binding of substrates with large aromatic substituents [ 37 ] . In the modeling studies on CcrA [ 42 ] , Asn233 was predicted to interact with the β-lactam carbonyl on substrate, and mutagenesis studies have supported this prediction [ 43 ] . Although Asn233 is sequence conserved in L1 [ 35 ] , it is located 14Å away from the modeled position of the β-lactam carbonyl and was predicted not to play a role in substrate binding to L1 [ 37 ] . On the other hand, the substrate-binding model predicted that Tyr228 was in position to offer a hydrogen bond to the β-lactam carbonyl and participate in an oxyanion hole that was proposed to form as the substrate was hydrolyzed [ 37 ] . By using the crystal structure and modeling studies on L1, Ullah et al.
Hibert et al proposed an early model for the antagonist pharmacophore of the 5-HT 3 R [ 18 ] . According to this model, all 5-HT 3 R antagonists contain an aromatic ring, a carbonyl oxygen or bioisosteric equivalent, and a basic nitrogen.
While Lerisetron contains no carbonyl group, the second nitrogen contained in the benzimidazole heterocycle could act as bioisostere of this functional group [ 22 ] . Orjales demonstrated the importance of the N-benzyl group by synthesizing several N1 substituted analogs of Lerisetron.
For example, steric hindrance caused by substitution of bulky Phe for Gly78 (residue numbers are given with reference to Lhcbl) in the position designated a 6 [ 29 ] prevented this peptide carbonyl, non-H-bonded because of Pro82 one helical turn further, from serving as a ligand (see Fig.
Alternatively, these Chls may coordinate with peptide carbonyl groups.
