Amino acid or a compound with similar structure as amino acid reacts with hydroxy imidazole compounds in a water solution to obtain the novel amino acid imidazolium ionic liquid and water. Compared with the prio
Intramolecular nucleophilic attack by the imidazole nitrogen can cause lactam formation158 as well as fission of peptide bonds.159 Isoleucine (Ile or I) ((2S,3S)-2-amino-3-methylpentanoic acid) is a nonpolar, neutral, aliphatic amino acid with the formula HOOCCH(NH2)CH(CH3)CH2CH3. Having a...
It is classified as a non-polar, uncharged, branched-chain, aliphatic amino acid. Histidine Histidine is an α-amino acid that is used in the biosynthesis of proteins. It contains an α-amino group, a carboxylic acid group, and an imidazole side chain, classifying it as a positively ...
3). In contrast, the partitioning behavior of the entire amino-acid alanine with blocked, charged, or notermini is substantially different and the free energy minimum shifts to the head-group region. The difference arises mainly due to the unscreened partial charges on the backbone that ...

Dehydroalanine and dehydrobutyrine Dehydroalanine (ΔAla) is the simplest dehydroamino acid with the shortest side chain constituted by the methylidene group. Thus, it does not reveal geometrical isomers. Contrarily, dehydrobutyrine (ΔAbu) is the simplest α,β-dehydroamino acid, which has ...
(amino acid)s significance as replacements forPEG, which is not readily biodegradable in vivo. In addition, the functional group that the starting amino acid possesses is transferred to the corresponding polymer, offering a polymer that may be further modified with cell-targeting groups, cross-...
However, direct comparisons cannot be made with the results obtained in this study because previous works did not quantify the amount of Fe3+ reduced. Different factors such as the enzymes used for hydrolysis, molecular weight of the peptides and amino acid composition can be responsible for the...
