One of the overarching themes in nature is that form meets function, meaning that the shape of an object determines how well the object can perform its function. This book begins with some basics about specificity of shapes and the four increasing levels of protein structure. Most of this book examines how epinephrine (adrenaline) can cause the liver to release glucose when a person experiences a fight or flight response. Whenever someone gets scared, all of their cells are bathed in epinephrine. A subset of those cells will respond directly to this hormone, and the liver cells prepare other cells for the extra energy they might need to survive. This book presents some of the data that revealed how the information of fear is carried inside liver cells. This book will also consider how and why some cell membranes are wavy. In short, this book looks at the structure/ function relationship at the molecular level

Symmetry and topology in chemical reactivity / Pieter E. Schipper
Singapore : World Scientific, 1994
xii, 272 pages. : illustrations ; 23 cm.
Ký hiệu phân loại (DDC): 541.39
This well-illustrated book develops, using only the ideas of basic quantum chemistry (e.g. perturbation and symmetry theory), a fundamental conceptual and theoretical framework for chemical reactivity. By feeding the role of symmetry and chemical group topology directly into the development, the analysis generates and explains the successful features of simpler reactivity theories (e.g. frontier orbital theory, the isolobal concept, PMO theory, the Woodward-Hoffmann rules), as well as defines their limitations. The unifying construct is that of a group-resolved correlation diagram
