When the secondary structure of a protein folds into a globular shape, the tertiary structure is formed. An alpha-helix and a beta-sheet are the two primary forms of secondary structures that proteins can have.
What is protein synthesis?
Protein synthesis is the process of making proteins.
It is carried out within the cell in biological systems. It occurs in the cytoplasm of prokaryotes.
In eukaryotes, it begins in the nucleus with the formation of a transcript (mRNA) of the coding section of the DNA. The transcript exits the nucleus and travels to the ribosomes for translation into a protein molecule with a particular amino acid sequence.
What Are the Four Protein Structure Types?
- The primary structure: The main structure of a polypeptide chain is defined as the sequence of amino acids. Proteins are classified into 20 different amino acids. The fundamental sequence of amino acids in a protein is the order in which they appear.
- Secondary structure: The secondary structure of a protein refers to the backbone's regular, recurring folding patterns. The alpha-helix and the beta-sheet are the two most prevalent folding patterns.
- Tertiary structure: It refers to the whole polypeptide chain folded into a precise 3D form. Enzymes are typically compact spherical tertiary structures.
- Structure of Quaternary: Many proteins are made up of several polypeptide chains. A protein's quaternary structure outlines how its many subunits are packed together to form an overall structure.
Thus, we can conclude that the tertiary structure of protein synthesis is represented by the coiling of the protein chain backbone into an alpha helix.
