Aging is not a process of decline; it is a process of continuing to meet life's challenges and of growing into a complete human being. Aging is a complex interaction of genetics, chemistry, biology and physiology; topics that are worthwhile to address. This book offers a good introduction to the biology and chemistry of aging. It emphasizes on cellular aging, and covers different areas and theories which deal with mechanism of aging. If the reader has some background in biology, then this is an excellent introductionary book to the biology and chemistry of aging. The book includes information...

This book helps students and readers visualize the three-dimensional atomic and molecular structures that are the basis of chemical action. An integral part of the text is to develop an explanation to hybridization which introduced to explain molecular structure when the valence bond theory failed to correctly envisage them. Dr. Elsersawi presents the quantum theory of the electronic structure of atoms and focuses on the electronic structures and reactivity of atoms and molecules. Many questions and answers of chemical components are introduced, using molecular orbital, and hybridization of...
