Yogurt is a valuable health food for both infant and elderly people. The nutritional constituents of yogurt are derived from the milk used in making it‚ those that are synthesized by the lactic acid bacteria and those that are added by the manufactures. The nutritional value of the milk protein is well-preserved during the fermentation process. Like most dairy products‚ it is a good source of protein. The milk proteins in yogurt are partially hydrolyzed and therefore become more digestible. In comparison

Chapter 2 Integrin Structure and Function Manakan Betsy Srichai and Roy Zent Abstract Integrins are a large family of heterodimeric glycoprotein receptors first discovered over twenty years ago. They exist as two noncovalently bound a- and b- subunits that function as adhesion molecules and play key roles in many biological processes including actin cytoskeleton organization and transduction of intracellular signals regulating cellular functions. Integrins bind a variety of extracellular matrices
