  • Thiamine (Vitamin B1) Thiamine was the first B vitamin to be identified and is therefore also referred to as vitamin B1. Thiamine functions in the decarboxylation of αketoacids, such as pyruvate α-ketoglutarate, and branched-chain amino acids and thus is a source of energy generation. In addition, thiamine pyrophosphate acts as a coenzyme for a transketolase reaction that mediates the conversion of hexose and pentose phosphates.

  • This book is about what we consider the essentials of human nutrition. The science of human nutrition deals with all the effects on people of any component found in food. This starts with the physiological and biochemical processes involved in nourishment—how substances in food provide energy or are converted into body tissues, and the diseases that result from insufficiency or excess of essential nutrients (malnutrition). The role of food components in the development of chronic degenerative disease like coronary heart disease, cancers, dental caries, etc.

  • The functional replacement of the primary ubiquinone (QA) in the photosynthetic reaction center (RC) from Rhodo-bacter sphaeroideswith synthetic vitamin K derivatives has provided a powerful tool to investigate the electron transfer mechanism. To investigate the binding mode of these qui-nones to theQAbinding sitewe have determined the binding free energy and charge recombination rate from QA ± to D + (kAD) of 29 different 1,4-naphthoquinone derivatives with systematically altered structures.
