👉 Esteros are a class of proteins that play important roles in the body's immune response. They consist of two main types, known as proteoglycans and glycosaminoglycan (GAGs). Proteoglycans are long chains of amino acids linked together with sugar molecules, while GAGs are made up of a series of repeating units called oligosaccharides that are present in the cell membrane. Esteros help to stabilize this structure by providing structural support
