Chemo-Enzymatic Route to Synthesis of Biodegradable Polymers and Glycolipid Analogs
New catalytic synthetic methods in organic chemistry that satisfy increasingly stringent environmental constraints are in great demand by the pharmaceutical and chemical industries. Studies over last 15 years have revealed that activity of enzymes can be increased in organic solvents rather than the...
