Proteins are chains of amino acids, some of which are glycosidic linkages. These linkages can be either alpha or beta. Glycosidic linkage types in proteins function as bridges between the polypeptide chain and a sugar molecule. This article will explore how these linkages work in protein analogs, what they do to help cells communicate with one another, and more.
What is a Glycosidic Linkage?
Explained by: Dr. Amy Yuen, Ph.D., Chemistry Expert and Science Writer The glycosidic linkage is an analogy to the protein analog in that it functions similarly as a bridge between two other substances ,in this case, a sugar molecule and another component of proteins (amino acids).
As with linkages found in proteins, there are alpha-linkages and beta-linkages which contain either one or two sugars respectively. The difference lies in their mechanism; while both alpha-links involve enzymes called glycoside hydrolases for the break down process only beta-links undergo hydrolysis before being broken down.
