Description: Pullulan is a neutral polymer composed of α-(1,6)-linked maltotriose residues, which in turn are composed of three glucose molecules connected to each other by an α-(1,4) glycosidic bond. It is non-toxic, non-immunogenic, non-carcinogenic and non-mutagenic in nature. The structure of pullulan consist unique linkage pattern with two α-(1 → 4) and one α-(1 → 6) glycosidic bonds in maltotriose repeating units (G3). Pullulan endows distinctive physical traits due to the presence of nine hydroxyl groups on glucopyranose rings of G3 units. It can be derivatized in various forms by substituting these hydroxyl groups to enhance its utility in biomedical applications. L-Theanine (γ-glutamylethylamide), an amino acid naturally found abundant in tea leaves, has positive effects especially on relaxing, cognitive performance, emotional status, sleep quality, cancer,cardiovascular diseases, obesity, and common cold.
