This textbook provides a comprehensive foundation in health sciences and chemistry, beginning with the essential principles of scientific measurement and progressing through the structure and behavior of matter. Early chapters introduce key topics such as significant figures, scientific notation, unit conversions, precision and accuracy, and the classification of measurement systems. The text then builds toward a deeper understanding of atomic structure, the periodic table, chemical bonding, energy and matter, and the properties of solutions and chemical reactions, establishing a strong conceptual and quantitative base for scientific study.
In its later chapters, the book transitions into a detailed exploration of organic and biochemistry, including acids and bases, hydrocarbons, functional groups, biomolecules (such as carbohydrates, lipids, proteins, and nucleic acids), and metabolic processes. It also covers enzymes, cellular energy production, and genetic principles such as DNA replication, transcription, and protein synthesis. Supporting appendices provide reference materials on periodic trends, functional groups, molecular geometry, common ions, and biochemical cycles.

Julian Davis, Ph.D. is a Professor of Organic Chemistry at the University of the Incarnate Word. He earned a B.S. in Chemistry with honors from North Carolina State University, followed by an M.A. and Ph.D. in Chemistry from the University of Texas at Austin. Following his graduate studies, Dr. Davis worked as a Research Scientist with Texas Fluorescence (TefLabs) and later served as a Teaching Post-Doctoral Associate at St. Edward’s University in Austin, Texas. He joined the faculty at the University of the Incarnate Word in 2006, where he continues to contribute to undergraduate chemistry education and instruction in organic chemistry.
Dr. Howard joined The University of Incarnate Word as an adjunct professor in 2018 and became a full-time Instructor for the Department of Chemistry and Biochemistry in 2021. Prior to becoming full-time in 2021, she worked as an adjunct professor for Northwest Vista College in the Natural Science Department. Dr. Howard graduated with her Doctorate in Chemistry from Texas Tech University in 2016 with an interest in drug design for ergosterol-dependent infectious diseases. She is currently working on implementing a CUREs, Course-Based Undergraduate Research Experience, based on the Malate Dehydrogenase Enzyme for the Biochemistry I Lab. A certified FLIGHT Mentor with over ten years of teaching experience in chemistry, she has a strong passion to inspire, encourage and connect to the younger generation.
