What role do such sugar coated proteins play in the life of the cell?

Sugar-coated proteins, known as glycoproteins, play crucial roles in cellular functions. They are involved in cell recognition, signaling, and adhesion processes, facilitating communication between cells and their environment. Additionally, glycoproteins are essential for immune responses, as they help the body distinguish between self and foreign cells. Overall, their diverse functions are vital for maintaining cellular integrity and overall organismal health.
