Influence of the pH on the formation of pyrazine compounds by the Maillard reaction of L-ascorbic acid with acidic, basic and neutral amino acids. J Chem Eng 2012;7:455-62.Yu, A. N., Tan, Z. W., & Shi, B.-A. (2012a). Influence of the pH on the formation of pyrazine ...
Step 1: Understand the Classification of Amino Acids Amino acids are classified into three categories: neutral, acidic, and basic. This classification is based on the functional groups present in their structure. Step 2: Identify Acidic Amino Acids Acidic amino acids are characterized by having two...
Partitioning of acidic, basic and neutral amino acids into imidazolium-based ionic liquids In this paper, partitioning behaviors of typical neutral (Alanine), acidic (Glutamic acid) and basic (Lysine) amino acids into imidazolium-based ionic liqu... G Absalan,AL Sheikhian - 《Amino Acids》 被...

gradually, although it should be noted that H2L occurs at a relatively high pH. We consider that system H2L contains two arginine residues. This high stability may be due by the formed strong guanidino aggregates. The modified groups are not ionized at neutral pH or at weak basic pH ...
Provided is an inhibitor of reactions between collagen peptides and acidic polysaccharides in foods or drinks, said inhibitor comprising a neutral or basic amino acid as an active ingredient. Also provided is an acidic jelly-like food ha... M Shinsei,K Hosozawa,Y Narahara 被引量: 0发表: 0...
Single mutations of residues D39 and E81 into neutral amino acids did not trigger dimerization, but even stabilized the monomeric state at neutral pH (Fig. 4a). Accordingly, the charged side chains of both residues are involved in electrostatic interactions with basic residues of the second ...
Substitution of K186 in TY1 by Arg reduced the original activity of this enzyme to 25%, while replacement by the neutral amino acid l-Thr led to an almost complete loss of the aminoacyl adenylation of phenylalanine.145,169 Though in both cases the catalytic activity of this protein is ...
Under acidic conditions, the most basic silanol species are most likely to be protonated. Therefore, condensation reaction may occur preferentially between neutral species and protonated silanols situated on the end groups of chains. As the result, the final gel is mostly an extended, weakly ...
