Flavonoids are divided into many classes and subclasses, each with a slightly different chemical structure and function. Classes of flavonoids include flavanols, flavanones, catechins, anthocyanins, and isoflavones. 

The SFC separation of nonsteroidal anti-inflammatory drugs (NSAIDs) was investigated by Jagota and Stewart [6]. These compounds vary in chemical structure and functional group chemistry and provide a representative sample of acidic drugs to study. Using a 10-m x 50-fim ID...

There are three general adsorbent classes used most often in solid phase extraction applications polar, ion-exchange, and nonpolar. Each class exhibits unique properties of retention and selectivity based on interactive properties of the products and the adsorbent surface. If the chemical structure and functional groups of desired products are known, this information can be used in choos-... 

Most of the lipids found in the body fall into the categories of fatty acids and triacylglycerols glycerophospholipids and sphin-golipids eicosanoids cholesterol, bile salts, and steroid hormones and fat-soluble vitamins. These lipids have very diverse chemical structures and functions. However, they are related by a common property their relative insolublity in water.

The physical properties of lipids derive directly from their chemical structures and functional groups. Physical properties greatly influence the functions of lipids in foods and the methods required for manipulation and processing. They can also be used to assess the purity or quality of lipid material in reference to known standards or preferred characteristics. 

R and D are Identical, and P has the same chemical structure and functionality, but with different molecular weights. Only the stoichiometry changes for the other compositions R, D, and P are the same. 

Organic materials can be tuned chemically in order to adjust the desired properties, such as the band gap, solubility, etc. A vast variety of chemical structures and functionalities of organic materials is basically available.

All naturally occurring lipids from botanical sources (plants) or zoological sources (animals and humans) could potentially be used in the production of bioplastics. They have the same chemical structure and function in a very similar manner. Cholesterol (and its related esters) and fatty acids are commonly found in zoological sources, although the fats tend to be of a heavily saturated nature. It is feasible to create other products such as biodiesel from extreme sources including liposuction fat. However, a lack of volume and more importantly ethical approval have prevented their uptake further. The remainder of this chapter will focus on the use of triglycerides from plants and their related compounds for bioplastics production.
