Detailed explanation-1: -Covalent bonds involve the equal sharing of an electron pair by two atoms. Examples of important covalent bonds are peptide (amide) and disulfide bonds between amino acids, and C–C, C–O, and C–N bonds within amino acids.
Detailed explanation-2: -These bonds are stronger and much more common than are ionic bonds in the molecules of living organisms. Covalent bonds are commonly found in carbon-based organic molecules, such as DNA and proteins.
Detailed explanation-3: -Covalent bonds result from a sharing of electrons between two atoms and hold most biomolecules together.
Detailed explanation-4: -Covalent bonds are very strong bonds. They’re very important in biology because they’re very stable and because most biological molecules are made with covalent bonds. These biological molecules are then very stable. So, atoms with more than one valence electron-let’s take carbon for example.
Detailed explanation-5: -Ionic bonding involves electrostatic interactions between oppositely charged ions, and can significantly enhance the binding strength of biomolecules immobilized to materials.
