The secretions of the exocrine pancreas provide for digestion of a meal into components that are then available for processing and absorption by the intestinal epithelium. Without the exocrine pancreas, malabsorption and malnutrition result. This chapter describes the cellular participants responsible for the secretion of digestive enzymes and fluid that in combination provide a pancreatic secretion that accomplishes the digestive functions of the gland. Key cellular participants, the acinar cell and the duct cell, are responsible for digestive enzyme and fluid secretion, respectively, of the exocrine pancreas. This chapter describes the neurohumoral pathways that mediate the pancreatic response to a meal as well as details of the cellular mechanisms that are necessary for the organ responses, including protein synthesis and transport and ion transports, and the regulation of these responses by intracellular signaling systems. Examples of pancreatic diseases resulting from dysfunction in cellular mechanisms provide emphasis of the importance of the normal physiologic mechanisms.

Enzymes, which work as organic catalysts for chemical reactions, are of interest to a wide range of scientific disciplines. The Source Book of Enzymes provides a worldwide listing of commercially available enzymes, offering the widest possible selection of enzyme products for specific applications. The Source Book of Enzymes answers these important questions and many more: Where can I find a particular enzyme? What enzymes are available for purchase? How do I select the appropriate enzyme for my application? How do the available enzymes differ from one another? What are the reaction conditions for optimum enzyme performance? Who sells the enzyme I need? The reliable research tool you will turn to again and again With the Source Book of Enzymes you will save hours of research time once wasted on searching through catalogs and product data bulletins. This practical reference tool makes the selection process easy by providing systematic and comparative functional information about each enzyme. Its global scope ensures that you will find the enzyme and supplier most suited to your needs and geographical location. Students and educators; researchers in academia, industry and government; bioengineers and biotechnologists, and purchasing agents will find this an invaluable resource for conducting competitive assessments, identifying new product trends and opportunities, identifying enzyme properties, and ordering specific enzymes.
