What is Biochemistry? The chemistry of life!  The study of biomolecules: StructurePropertiesInteractionsReactions Biochemists want to understand everything about all the molecules of life. This is a big job!

Life is diverse and complex! There are millions of different species on earth Each contains thousands of different types of molecules

Biochemists take advantage of similarities Different species are related; they evolved from a common ancestor Biomolecules and biochemical systems from different species are related

Biochemists take advantage of similarities Many biomolecules are complex polymers of basic units monosaccharide (sugar) units Protein (Polypeptide) DNA molecule nucleotide units (sugar + phosphate + base) amino acid units Carbohydrate (Polysaccharide)

The world of biomolecules

Human cells are ~10 μm in length (~1000x shorter than your finger tip) Figures from “The Machinery of Life” by David Goodsell

Macromolecules are ~10 nm in length (~1000x shorter than the length of a cell) Figures from “The Machinery of Life” by David Goodsell

Organic molecules are ~10Å (1nm) in length (~10x shorter than macromolecules) Figures from “The Machinery of Life” by David Goodsell

Cells are crowded full of biomolecules E. coli cell (30,000×) (( in rapid, chaotic motion )) Cell Wall (1,000,000×) Cytoplasm (1,000,000×) Protein mRNA tRNA Ribosome DNA Carb. Figures from “The Machinery of Life” by David Goodsell
