Ultrasound Depolymerization and Characterization of Poly- and Oligosaccharides from the Red Alga (C. Agardh) J. Agardh 1842.

Red seaweed carrageenans are frequently used in industry for its texturizing properties and have demonstrated antiviral activities that can be used in human medicine. However, their high viscosity, high molecular weight, and low skin penetration limit their use. Low-weight carrageenans have a reduced viscosity and molecular weight, enhancing their biological properties.
