Biochemistry - Water, pH and Macromolecules - Discussion

I think ionic bond is strongest that's why ionic compounds have extraordinary high M.P and B.P like NACL.

Covalent bond are strongest bond in chemistry formed by sharing of electrons and require more energy to break them. This fact explains why primary structure of biomolecules like DNA, RNA and Proteins have covalent bond in their structure. The rest of option are nothing but non covalent bond and can be easily broken down by low energy. This explains why the binding between the substrate and enzyme occurs by non covalent interaction. This makes the enzyme reusable.

Covalent bond are strongest bond Covalent bonds are the strongest of all bonds involving organic compounds. The hydrogen bonds help keep the tertiary structure together, but typically the more covalent (and hydrogen) bonds that a structure has, the harder it is to break up the molecule. Sulfide bonds are very strong, they are in DNA, RNA, amino acids, and plenty other compounds that make up the entire body. Cysteine and Methionine are the amino acids that have sulfide, and when they form those bonds, they amino acids (or protein eventually) usually has a structural role, but not always.

Covalent bond is used in pharmectiual drugs.

Covalent bond are strongest bond.

Covalent bonds are strongest chemical linkage, because all of the metal molecules in atom are linked by covalent bond.
