👉 Ligative refers to a chemical reaction in which two or more molecules bond together through a common shared link, such as a hydrogen atom. In the context of biology and chemistry, ligates are commonly used to construct complex structures or modify existing ones. For example, consider the formation of a protein chain by linking amino acids together through a specific sequence of hydroxyl groups. This process is known as glycosylation, where a sugar molecule attached to a protein backbone binds to amino acids on the
