This book is intended for students who are preparing for careers in health fields such as nursing, physical therapy, podiatry, medical technology, agricultural science, public health, and nutrition. The chemistry courses taken by these students typically include material covered in general chemistry, organic chemistry, and biochemistry, compressed into a 1-year period. Because of this broad requirement, many students feel overwhelmed. To help them understand and assimilate so much diverse material, we offer the outline of these topics presented in the text that follows. Throughout we have kept theoretical discussions to a minimum in favor of presenting key topics as questions to be answered and problems to.
