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.
Making and breaking of polymers: Dehydration synthesis: is an anabolic process by which two molecules are chemically bonded through the use of enzymes and a loss of water. glucose + glucose + enzyme = maltose + water + enzyme. Hydrolysis: is a catabolic process by which the bond between monomers are broken by the enzyme and the addition of water. sucrose + water + enzyme = glucose + fructose + enzyme.
