Detailed explanation-1: -The tertiary structure of a protein consists of the way a polypeptide is formed of a complex molecular shape. This is caused by R-group interactions such as ionic and hydrogen bonds, disulphide bridges, and hydrophobic & hydrophilic interactions.
Detailed explanation-2: -R group interactions that contribute to tertiary structure include hydrogen bonding, ionic bonding, dipole-dipole interactions, and London dispersion forces – basically, the whole gamut of non-covalent bonds.
Detailed explanation-3: -The tertiary structure of a protein is held together by interactions between the the side chains-the “R” groups. There are several ways this can happen. Some amino acids (such as aspartic acid and glutamic acid) contain an extra-COOH group.
Detailed explanation-4: -Explanation: Tertiary structure is stabilized by multiple interactions, specifically side chain functional groups which involve hydrogen bonds, salt bridges, covalent disulfide bonds, and hydrophobic interactions.
Detailed explanation-5: -Tertiary structure comprises four types of covalent and non-covalent interactions: – Hydrogen bonds of polar amino acid residues. – Ionic bonds between amino acids with oppositely charged side chains. – Hydrophobic interactions in which non-polar amino acids cluster.
