what is the structure of protein

Proteins have four different types of structure:-

1)Primary structure - single linear chain of amino acids.

2)Secondary structure-chain of amino acids forming helix or beta pleated sheet.

3)Tertiary structure - polypeptide chain form a complex 3D structure by forming a bonding between the amino acids.

4)Quarternary structure- two or more polypeptide chains are bonded together to form this structure.

Protein structureis thebiomolecular structureof aproteinmolecule. Each protein is apolymer specifically apolypeptide that is a sequence formed from various L-α-amino acids(also referred to as residues). By convention, a chain under 40 residues is often identified as apeptide, rather than a protein. To be able to perform their biological function, proteins fold into one or more specific spatial conformations, driven by a number of non-covalentinteractions such ashydrogen bonding,ionic interactions,Van der Waals forces, andhydrophobicpacking. To understand the functions of proteins at a molecular level, it is often necessary to determine their three-dimensional structure. This is the topic of the scientific field ofstructural biology, which employs techniques such asX-ray crystallography,NMR spectroscopy, anddual polarisation interferometryto determine the structure of proteins.
