O = C, CH ... O = C, NH ... N and C = H ... N is the main factor for the formation of protein α-helix structure, β-sheet structure and DNA double helix structure. , Protein replication and genetic information transfer process plays an important role. Accurately and quickly calculate the potential energy curves of the hydrogen bonding strength (NH ... O = C, CH ... O = C, NH ... N and CH ... N) existing in the biological system and the hydrogen bonding strength with the molecular geometry (distance and angle) Correctly modeling (correctly understanding and understanding) biological processes such as protein folding mechanism and DNA double helix formation mechanism are of great significance and have important guiding value for the design and synthesis of biomolecular materials with special functions. This paper mainly introduces the dipole-dipole hydrogen bond model established in recent years and its application in rapidly predicting the hydrogen bond strength and the potential energy curve of hydrogen bonding between polypeptide-polypeptide molecules and nucleic acid-base-peptide molecules.
