"Conformational" refers to the shape or arrangement of something, especially molecules. It describes how the parts of a structure fit together and interact with each other. Full definition
We see manifold applications, such as studies of conformational changes in amyloid structures on the molecular level, the mapping of nanoscale protein modifications in biomedical tissue or the label - free mapping of membrane proteins. (sciencedaily.com)
While computation time and therefore explorable conformational space improves, the ability to distinguish native from non-native conformations decreases. (meilerlab.org)
