Chem315 BIOCHEMSTRY  1 Biochemistry An Overview Prepared by Nesteve John B. Agosto, RCh, MSc  What is biochemistry?  Biochemistry is the study of the chemical substances found in living organisms and the chemical interactions of these substances with each other Biochemistry is a field in which new discoveries are made almost daily about how cells manufacture the molecules needed for life and how the chemical reactions by which life is maintained occur. What are the types of biochemical substances? Major Types of Biochemical Substances BIOCHEMICAL SUBSTANCES BIOINORGANIC substances found BIOORGANIC SUBSTANCES within a living organism SUBSTANCES substances that do not substances that contain contain carbon carbon BIOINORGANIC SUBSTANCES Water Inorganic Salts BIOORGANIC SUBSTANCES Carbohydrates Proteins Lipids Nucleic Acids  Water Proteins (about 70%) (about 15%) Mass Inorganic composition data Lipids in terms of Salts types of (about 5%) biochemical (about 8%) substances Carbohydrates Nucleic Acids (about 2%) (about 2%) Although we tend to think of the human body as made up of organic substances, bioorganic molecules make up only about one-fourth of body mass. The bioinorganic substance water constitutes over two-thirds of the mass of the human body, and another 4%–5% of body mass comes from inorganic salts.  As isolated compounds, bioinorganic and bioorganic substances have no life in and of themselves. Yet when these substances are gathered together in a cell, their chemical interactions are able to sustain life.  Thanks! Reference: General, Organic, and Biological Chemistry by H.
