So cystines are a type of amino acid that have a special thiol group as part of its side-chain. Halogen bonding is a type of non-covalent interaction which does not involve the formation nor breaking of actual bonds, but rather is similar to the dipoledipole interaction known as hydrogen bonding.In halogen bonding, a halogen atom acts as an electrophile, or electron-seeking species, and forms a weak electrostatic interaction with a nucleophile, or electron-rich species. Disulfide Bond. These are very strong covalent bonds found between cysteine residues that are in close proximity in space. It can also be called a eupeptide bond to distinguish it from an isopeptide bond, which is another type of amide bond These chemical alterations range from the enzymatic cleavage of peptide bonds to the covalent additions of particular chemical groups, lipids, carbohydrates, or even entire proteins to amino acid side chains. : 2 Nylon polymers can be mixed with a wide variety of additives to achieve many different property variations.

A covalent bond is a chemical bond that involves the sharing of electrons to form electron pairs between atoms.These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding. However, polyatomic ions are held together by covalent bonds, so this compound contains both ionic and covalent bonds. But these double bonds are much weaker than the equivalent double bonds to oxygen atoms in O 3 or CO 2. Ionic bonds are weak bonds and they are very fragile in an aqueous medium.. Even a change in the pH may breakdown the ionic bonds.. This is the reason for the denaturation of proteins in the acidic or basic medium.. Tertiary and quaternary structures of proteins are stabilized by ionic bonds. Hence, thioldisulfide exchange is inhibited at low pH (typically, below 8) where the protonated thiol form is favored relative to the deprotonated thiolate form.
