Hyaluronan, also known as hyaluronic acid, is a large glycosaminoglycan composed of repeating disaccharide units. It plays a crucial role in providing structural support, hydration, and facilitating cellular processes in connective tissue, skin, and the extracellular matrix in biological systems. We present a coarse-grained (CG) model of hyaluronic acid (HA) and its constituent residues,
