Answer:
Protein structure deals with the arrangement of amino acids in the polypeptide chains of a protein molecule.
Step-by-step explanation:
There are 4 types of protein structure
1 primary structure
2 secondary structure
3 Tertiary structure
4 quaternary structure
Protein folding helps a protein to achieve its native three imensional structural configuration by the formation of various covalent and noncovalent interaction between different parts of the polypeptide chain of the protein molecule.The covalent and non covalent interaction include di sulfide linkage,hydrogen bonding, ionic interaction etc.
Prions are a type of disease that is called by abnormal folding or misfolding of a protein molecule.This ultimately result in the accumulation insoluble protein aggregates in the cell resulting in the formation of various diseases such as Alzheimer disease,Parkinson disease.
