Conformational Analysis of Neutral and Ionic Arginine Forms Using DFT Methods.

ABSTRACT: Arginine (Arg) is an essential amino acid with a side chain that contains a positively charged group. Arg plays a pivotal role in maintaining the overall charge balance of a protein due to the presence of the guanidino group as its side chain. Consequently, Arg has the capacity to influence various functional characteristics of proteins, encompassing aspects such as folding, solubility, and aggregation. Moreover, the ionic forms of this amino acid can be deemed to be critical determinants in the formation of molecular interactions between proteins and organic compounds. The versatile properties of Arg encompass a broad spectrum of effects, ranging from cellular-level biochemical events to the overall biological functions of the organism. Intriguingly, our knowledge remains incomplete regar
