Abstract (1‚3)-β-D-Glucans are naturally occurring polysaccharide polymers found in the cell walls of various fungi and bacteria. They are structurally composed of D-glucose polymers consisting of linear (1‚3)-β-D-glucosidic linkages of varying length and also branched polymers with side chains attached as (1‚6)-β-D-linkages. These side chains can be (1‚3)-β or (1‚6)-β glucoside chains of varying length. β-Glucans belong to a class of drugs called biological response modifiers (BRMs) due to their

monomer and polymer. M-Monomers are small molecules which may be joined together in a repeating fashion to form more complex molecules called polymers. P- A polymer may be a natural or synthetic macromolecule comprised of repeating units of a smaller molecule. 5. Describe dehydration (condensation) and hydrolysis reaction. Include a diagram to illustrate both 6. What’s the biological relevance of dehydration and hydrolysis reactions ― that is of being able to assemble polymers from monomers

Synthetic/natural composites have a stable structure because of synthetic polymers and a suitable surface for cells attachment because of natural polymers(Wang et al.‚ 2016). PLA is a biocompatible‚ biodegradable‚ and synthetic polymer that has been used extensively in tissue engineering. In this study‚ PLA was blended with chitosan as a natural component. PLA scaffold

Chapter I INTRODUCTION Plastics found everywhere. Bottles‚ utensils‚ food packagings are some examples of plastics that we use and see in our daily lifestyle. We can easily have plastics for our convience because it was sold in our market directly thus spending a little of our money. Behind these things our typical perception about plastic is just a bit of what plastics really are. For those people who are concious about our environment ‚ they say that plastics cause a wide environmental problem
