Empowering Innovation: Your Partner in Gellan Analysis Services

Gellan is extensively utilized in various pharmaceutical forms, such as oral, ophthalmic, and nasal preparations. Its ability to biodegrade, lack of toxicity, rapid gelation when exposed to cations, high water absorption capacity, and potential for adhering to mucosal surfaces make it a valuable ingredient in a wide array of pharmaceutical formulations. CD BioGlyco provides a comprehensive Pharmaceutical and Biological Analysis Service, with a particular focus on our reliable multi-type Pharmaceutical Excipient Analysis Service. The specific gellan analysis services we provide are as follows.

• Our specialists employ rheometers for the assessment of the rheological characteristics of gellan solutions, encompassing viscosity, shear stress, and shear rate.
  • We determine the rheological properties of gellan by analyzing the relationship between shear stress and shear rate, which helps evaluate the rate and mechanism of drug release under different flow conditions.
  • Additionally, we assess the viscosity, elasticity, and other properties of gellan gels to aid in determining their encapsulation efficiency and stability for drug molecules.
  • We assist in evaluating the performance and compatibility of gellan for specific drug systems by analyzing their rheological properties under various conditions to guide the selection of drug formulations.
• CD BioGlyco provides the gellan thermal property measurement service by techniques such as differential scanning calorimetry (DSC) to investigate the thermal behavior and phase transition properties. The properties we test include melting point and enthalpy of melting.
• We utilize high-performance liquid chromatography (HPLC) to separate and identify the components of the drug. This allows us to quantify the amount of gellan present. Additionally, we employ Fourier transform infrared spectroscopy (FTIR) to study the molecular structure of gellan in the drug and gain insight into its chemical composition. Furthermore, we also utilize nuclear magnetic resonance spectroscopy (NMR) to provide information on the molecular structure of the gelling.

Frequently Asked Questions

• What is the molecular structure of gellan?
  Gellan is a polysaccharide polymer with a relatively complex molecular structure consisting of multiple glycosyl units. In general, the molecular structure of gellan consists mainly of glucose, galactose, and glucuronic acid. These monosaccharide units are linked together by different chemical bonds to form the polysaccharide chains of gellan.
• How does the degree of substitution of gellan affect its properties?
  The degree of substitution of gellan refers to the percentage of hydroxyl groups substituted in the polysaccharide chain. Changes in the degree of substitution can significantly affect the properties and functions of gellan, including its gel properties, stability, and solubility. An increase in substitution usually decreases the gel strength and elasticity of gellan. This is because the introduction of substituents may lead to weakened interactions between polysaccharide chains, which may affect the structural stability of the gel. The solubility of gellan usually increases with increasing substitution. This is because the introduction of substituents can break the hydrogen bonds and hydrophobic interactions between the polysaccharide chains, making gellan more soluble in water.
