What is exactly the significance of coordinate covalent bonds and how does it help us understand bond structure in general?

Coordinate covalent bonds are when a bond is formed from a lone pair from only ONE atom donating BOTH electrons. Remember a bond is two electrons. Take for example NH3 and BF3 bonding to NH3BF3. The bond between the N and B comes from the two electrons from the N, not 1 from N and 1 from B.

The ability to form coordinate covalent bonds allows the molecule to form a complex structure, thus the shape of the compound makes it biologically significant.

Coordinate covalent bonds allow certain atoms to complete the octet. Boron, a big example, needs to accept a whole lone pair from another atom to complete its octet.

What is the significance of the coordinate covalent bonds? Are these bonds involved in lewis acids and bases?

Coordinate covalent bonds relates to Lewis acids and bases because they can bond to form a coordinate covalent bond. A Lewis acid is missing a full octet since it has an empty orbital and a Lewis base has a free lone pair to share, thus forming a coordinate covalent bond. A metal ion binding to a chelator is an example.
