Explain the primary and tertiary structure of amino acids with suitable diagram
Answers
Explanation:
One example of a protein with a primary structure is hemoglobin. This protein, found on your red blood cells, helps provide the tissues throughout your body with a constant supply of oxygen. The primary structure of hemoglobin is important because a change in only one amino acid can disrupt hemoglobin's function.
Answer:
Primary structure of proteins: Refers to sequence of amino acids linked together through peptide bonds in a polypeptide chain. It also refers to position of disulphide bonds (-S-S) that are formed between the -SH groups of cysteine residues that are adjacent in space but not in the linear sequence of amino acids.
Tertiary structure of proteins: Refers to overall three-dimensional structure (native conformation) of a protein molecule. The tertiary structure is derived by further folding and super-folding of polypeptide chain(s) exhibiting secondary structure. The tertiary structure is stabilized by covalent disulfide bonds and various weak non-covalent bonds (hydrophobic interactions/van der Waal forces, ionic interactions and hydrogen bonding).
