Polymers: Introduction, Classification, Properties, Advantages

by

Introduction Polymers are large molecules composed of repeating structural units (monomers) connected by covalent bonds. These macromolecules can be natural (e.g., proteins, polysaccharides) or synthetic (e.g., polyethylene, polylactic acid). The versatility of polymers, such as their ability to modify drug release profiles, has made them central to the development of advanced drug delivery systems, particularly … Read more

Excipients in Pharmaceutical Formulations

by

Excipients are inactive substances formulated alongside the active pharmaceutical ingredient (API) of a medication. They serve a variety of roles that are critical to the creation, stability, and functionality of the final pharmaceutical product. While excipients do not exert therapeutic effects themselves, they are essential for the effectiveness, safety, manufacturability, stability, and patient acceptability of … Read more

Polysaccharides: chemical nature of starch and glycogen

by

Polysaccharides are complex carbohydrates composed of multiple monosaccharide units linked together through glycosidic bonds. These macromolecules can vary in size and structure, ranging from a few hundred to thousands of monosaccharide residues. Common examples of polysaccharides include starch, glycogen, and cellulose. Polysaccharides serve various functions in living organisms, such as energy storage (as in starch … Read more

Carbohydrates: Definition, Classification, chemical properties

by

Carbohydrates are organic compounds of carbon, hydrogen, and oxygen atoms, typically with a hydrogen-oxygen atom ratio of 2:1 (as in water). They serve as a primary energy source for living organisms and play essential structural and functional roles in cells. Carbohydrates include sugars, starches, and fibers and can be classified based on their chemical structure … Read more
