Algal Carrageenan as a Marine Biotechnology Resource in Cosmeceutical.Recently, researchers have developed an interest to isolate new bioactive chemicals from marine resources due to their various beneficial health impacts.IntroductionRecently, researchers have developed an interest to isolate new bioactive chemicals from marine resources due to their various beneficial health impacts. Among these marine resources, the marine algae are some of the most valued source of structurally bioactive compound. According to scientific studies, the cell walls of marine algae have substantial amounts of sulphated polysaccharides (SPs) like fucoidans that are present in brown algae, ulvans that are present in green algae and, most importantly, carrageenans that are present in red algae (Zhu et al. 2009).
