Which nutrient group is primarily responsible for providing structural components to cells?

Proteins are primarily responsible for providing structural components to cells due to their role as essential building blocks within the body. They are made up of amino acids, which link together to form various proteins that make up the cytoskeleton, membranes, and other critical structures in cells. This structural functionality is vital for maintaining the integrity, shape, and function of cells and tissues.

In addition to serving structural purposes, proteins are also involved in many other biological functions, including catalyzing biochemical reactions as enzymes, transporting molecules, and facilitating communication between cells. Their diverse roles highlight their importance in overall cellular health and function.
