This book provides a study of biochemistry research trends across a broad spectrum of applications. Topics discussed include the biochemical, physiological and therapeutic aspects of some components of the large class of lipids; streptavidin-biotin binding and immunomodulatory constructs; cardiac opioid peptides and classical opioid receptor systems; angiotensin converting enzyme inhibitors; phylogenomic analyses of the superprotein families of different metabolic systems; aptamers as the new biorecognition element for proteomic biosensing; the interactions of microorganisms with heavy oils and urinary adrenaline measurement in a forest environment setting.
