PLEASE GIVE ME A BRIEF DISCRIPTION OF VARIOUS STRUCTURE OF PROTEINS
Asked by | 12th Jun, 2009, 06:01: PM
Biochemistry refers to four distinct aspects of a protein's structure:
- Primary structure - the amino acid sequence of the peptide chains.
- Secondary structure - highly regular sub-structures (alpha helix and strands of beta sheet) which are locally defined, meaning that there can be many different secondary motifs present in one single protein molecule.
- Tertiary structure - three-dimensional structure of a single protein molecule; a spatial arrangement of the secondary structures. It also describes the completely folded and compacted polypeptide chain.
- Quaternary structure - complex of several protein molecules or polypeptide chains, usually called protein subunits in this context, which function as part of the larger assembly or protein complex.
