Conformational analysis is the study of the way a molecule changes shape when subjected to various conditions. This branch of chemistry is crucial to the understanding of molecular structure and function, and is often used to predict the behavior of biological molecules such as proteins and nucleic acids. Synonyms for this term may include molecular shape analysis, molecular modeling, molecular dynamics, and structure-function analysis. Each of these terms emphasizes a slightly different aspect of the field, but all share the goal of elucidating the connection between molecular structure and chemical reactivity. Ultimately, conformational analysis is a powerful tool for researchers in chemistry, biology, and biochemistry who seek to understand the fundamental processes of life at the molecular level.
