Macromolecules {often|frequently|usually|typically|generally|normally} exchange {between|in between|among|amongst|involving} functional states on timescales {that can|that may|that will|that could|which will|which can} be accessed with NMR spectroscopy and {many|numerous|several|a lot of|quite a few|lots of} NMR tools {have been|happen to be|have already been} {developed|created} to characterise the kinetics and thermodynamics {of the|from the|in the|on the|with the|of your} exchange processes, {as well|also|too|at the same time} {as the|because the} structure {of the|from the|in the|on the|with the|of your} conformers {that are|which are|which can be|which might be|that happen to be} involved. {However|Nevertheless|Nonetheless|Even so|On the other hand|Having said that}, {analysis|evaluation} {of the|from the|in the|on the|with the|of your} NMR {data|information} that report on exchanging macromolecules {often|frequently|usually|typically|generally|normally} hinges on {complex|complicated} least-squares fitting procedures {as well|also|too|at the same time} as human {experience|encounter|expertise|knowledge|practical experience} and intuition, which, in some {cases|instances|circumstances|situations}, limits the widespread use {of the|from the|in the|on the|with the|of your} {methods|techniques|strategies|approaches|procedures|solutions}. The applications of deep neural networks (DNNs) and artificial intelligence have {increased|elevated|improved|enhanced} {significantly|considerably|substantially|drastically} {in the|within the|inside the} sciences, and {recently|lately|not too long ago}, {specifically|particularly|especially}, {within|inside} the field of biomolecular NMR, {where|exactly where} DNNs are now {available|accessible|obtainable|offered|readily available|out there} for tasks {such as|like|including|for example|for instance|which include} the reconstruction of sparsely sampled spectra, peak {picking|choosing|selecting}, and virtual decoupling. {Here|Right here} we present a DNN for the {analysis|evaluation} of chemical exchange saturation transfer (CEST) {data|information} reporting on two- or three-site chemical exchange involving sparse state lifetimes of {between|in between|among|amongst|involving} {approximately|roughly|around|about} {3|three} – 60 ms, the {range|variety} most {frequently|often|regularly} observed {via|by way of|through|by means of} experiment.
