3D Structure of Biomolecules

The 3D structure of biomolecules like proteins and nucleic acids refers to their specific three-dimensional shape, which is crucial for their function. These molecules are made of smaller units arranged in precise ways, forming complex shapes such as coils, folds, or sheets. This 3D arrangement determines how they interact with other molecules, enabling biological processes like enzyme activity, DNA replication, and cell signaling. Understanding their structure helps scientists design drugs and understand diseases, as the shape dictates how these molecules behave in living systems.
