Proteins are large molecules composed of smaller constituents called amino acids. They are ubiquitous and essential for all life. The 3-dimensional structure and the function of a protein are intimately related. The process by which a protein achieves a final structure is referred to as protein folding.
In cells, genes encoded in DNA are transcribed into messenger RNA (mRNA). The mRNA can then be translated into an amino acid chain called a polypeptide (after the peptide bond connecting the amino acids). From here, the polypeptide must find and adopt a 3-dimensional conformation.
