WebThese bonds additionally stiffened the hydrogel and increased its viscosity. The statistical analysis using ANOVA with Tukey’s test gave the values of the probability p < 0.0001, confirming statistically significant differences between formulations F1–F3 containing different amounts of HA (3, 4, or 5 g of HA). WebIn the liquid state, water molecules are bound to each other by an average of three hydrogen bonds. Hydrogen bonds arise when a hydrogen that is covalently bound to an oxygen in one molecule of water nears another oxygen from another water molecule. The electrophilic oxygen atom “pulls” the hydrogen closer to itself. sebastian norck bayreuthWebThe word Hydrophilic means the part which has an affinity toward water or that part is water-loving or one polar compound that can able to react with water and due to its hydrophilicity, it requires a special membrane protein to pass through a lipid bilayer. sebastian niccals
