Patients with chronic hepatitis B have antibodies against hepatitis B, but these antibodies are not enough to clear the infection of the affected liver cells. The continued production of virus combined with antibodies is a likely cause of the immune complex disease seen in these patients.
1 Hydrolytic Degradation: ï This process occurs in polymers that are watersensitive active groups, especially those that take a lot of moisture. ï 2  Polymers that have an ability for hydrolytic destruction usually have heteroatoms in the main or side chain. Mechanism of Hydrolytic Degradation ï Hydrolytic degradation of members of the polylactide/glycolide family proceeds through four stages as represented in Figure 2: First stage of water diffusion followed by second stage, in which oligomers with acidic endgroups autocatalyze the hydrolysis reaction.
Hydrolysis usually means the cleavage of chemical bonds by the addition of water. When a carbohydrate is broken into its component sugar molecules by hydrolysis, this is termed saccharification. Generally, hydrolysis or saccharification is a step in the degradation of a substance OR in the language of chemistry The reaction of cation and anion or both with water molecule due to which pH is altered, cleavage of H-O bond in hydrolysis takes place. Hydrolysis can be the reverse of a condensation reaction in which two molecules join together into a larger one and eject a water molecule. Thus hydrolysis adds water to break down, whereas condensation builds up by removing water and any other solvents.
