What process involves monomers being joined by the removal of OH from one monomer and H from another?

The process described involves the joining of monomers through a reaction where a hydroxyl group (OH) is removed from one monomer and a hydrogen atom (H) is removed from another. This specific mechanism forms a covalent bond between the two monomers and results in the release of a water molecule (H2O). This reaction is known as dehydration synthesis or condensation reaction.

In dehydration synthesis, the removal of the components that make up water (H and OH) allows for the formation of larger molecules, such as polysaccharides, proteins, and nucleic acids, from smaller monomer units. The name "dehydration" reflects the loss of water in the process, and "synthesis" indicates that new larger molecules are being synthesized from smaller units.

Understanding this process is fundamental in biochemistry, as it illustrates how complex organic molecules are formed within living organisms, playing essential roles in structure and function.
