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.
