is the only protein known to contain a substantial proportion of hydroxyproline. Macromolecules are not always the final goal of the chemist-they may act as intermediates, reactants, or catalysts. The collagenous fibers are typically arranged in branching bundles of.
More-detailed considerations are given to certain particularly important and critical properties such as the solubility and permeability of polymeric systems. Chapters 4 through 9 describe how such properties are rooted in and dependent on the chemical structure. For most applications-textiles, films, molded or extruded objects of all kinds-the mechanical and the thermal behaviors of polymers are of pre ponderant importance, followed by optical and electric properties. The following chapters go into more detail. epidermal region exhibiting the most rapid cell division 7.
#TRANSLUCENT CELLS CONTAINING KERATIN FIBRILS SKIN#
major skin area that produces derivatives (nails and hair) 6. dermal layer responsible for fingerprints 4. The third chapter deals with the important question: How are these chemical and physical structures experimentally determined? The existing methods for polymer characterization are enumerated and discussed in this chapter. translucent cells in thick skin containing keratin fibrils 2. The immediate physical consequences, discussed in the second chapter, form the basis for the physical nature of polymers: the supermolecular interactions and arrangements of the individual macromolecules. What cells are mostly dead and filled with protein called keratin Hair cells. The first chapter is devoted to this broad objective. What skin area has translucent cells containing keratin fibrils in thick skin stratum lucidum. Polymers are very large and very complicated systems their character ization has to begin with the chemical composition, configuration, and con formation of the individual molecule. The first concern of scientists who are interested in synthetic polymers has always been, and still is: How are they synthesized? But right after this comes the question: What have I made, and for what is it good? This leads to the important topic of the structure-property relations to which this book is devoted.
