Biochemistry - Water, pH and Macromolecules - Discussion

If we describe the strength of an individual bond then the ionic bond is stronger than a covalent bond. While in network structure like diamond and silica covalent bond is stronger. As well as in the question, word molecule is used (covalent bond) not the word compound (ionic bond).

So, the answer is a covalent bond here while the individual ionic bond is stronger than an individual covalent bond.

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

Covalent bond are strongest bond.

Covalent bond is used in pharmectiual drugs.

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 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.

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

The easy way to determine that is to measure the energy it takes to break the bond. That quantity is called bond dissociation energy. The greater the energy it takes to break the bond, the stronger that bond must be. It turns out that most ionic bonds are considerably more difficult to break than covalent bonds. I think!

Covalent bonds are the strongest bonds whereas non-covalent are the weakest which is easier for the enzymes to break the bond.

The ionic bonds are stronger than that of covalent bonds. Because its dissociation energy is more than covalent bond.
