This study developed a simple method to distinguish the animal source of chondroitin sulfate (CS) through systematic investigations and comparisons of the terahertz (THz) spectral characteristics of CS with different animal sources. CS from shark had the lowest THz absorption coefficient. followed by that from cattle. with CS from piglet exhibiting the highest values. https://www.spidertattooz.com/Alpha-Industries-X-Detroit-Tigers-Green-59FIFTY-Fitted-Hat/
