Write a brief description of how the structure of a protein is made . Your description with one amino alkanoic acid and include the term ‘primary structure’, ‘secondary structure’ and ‘tertiary structure’ in your answer?
Solution
A structure is an appointment and organization of interrelated elements during a material object or system, or the thing or system so organized. Material structures include man-made objects like buildings and machines and natural objects like biological organisms, minerals and chemicals.
Complete answer:
Proteins structures are made by condensation of amino acids forming peptide bonds. The sequence of amino acids during a protein is named its primary structure. The secondary structure is decided by the dihedral angles of the peptide bonds, the tertiary structure by the folding of protein chains in space.
| Primary structure | Secondary structure | Tertiary structure |
|---|---|---|
| The simplest level of protein structure, primary structure, is just the sequence of amino acids during a polypeptide chain. Each chain has its own set of amino acids, assembled during a particular order. | The next level of protein structure, secondary structure, refers to local folded structures that form within a polypeptide thanks to interactions between atoms of the backbone. | The overall three-dimensional structure of a polypeptide is called its tertiary structure. |
| The sequence of a protein is decided by the DNA of the gene that encodes the protein (or that encodes some of the protein, for multi-subunit proteins). | The secondary structure is decided by the dihedral angles of the peptide bonds. | The tertiary structure is primarily thanks to interactions between the R groups of the amino acids that structure the protein. |
Note: The building blocks of proteins are amino acids, which are small organic molecules that contain an alpha (central) atom linked to an amino , a carboxyl , an atom , and a variable component called a side chain.
