1 Chem Lecture 2 Protein Structure Part 2 Question of the Day: Most proteins are made from a repertoire of 20 different amino acids. A small protein contains around 100 amino acids strung together in a polypeptide chain. How many different possible chains, containing 100 amino acids each, can be made when there are 20 different options for each of the amino acid in a chain? Proteins are polymers of amino acids There are 20 naturally occurring amino acids that are the building blocks used to make proteins. 2 What they share in common 3 What they share in common 4
2 What they share in common 5 What they share in common 5 What they share in common 6 What they share in common The common regions of each amino acid is what is used to join them together to form a polymer of amino acids. 7
3 The 20 amino acids are distinguished by their side chains. 8 The 20 amino acids are distinguished by their side chains. 8 Genomics The genetic code (1960 s) DNA: mrna: transcription A G T C U C A G transcription Protein: translation translation A C D E F G H I K L M N P Q R S T V W Y Chem 452, Lecture 1 - Introduction to Biochemistry 9 The side chains display differences in Physical properties Non-polar (hydrophobic) Polar (hydrophillic) Polar Charged (acids and bases) Polar neutral (hydrogen bonders) Chemical properties Acids Bases Nucleophiles 10

Proteins consist in whole or large part of amino acids. Simple proteins consist only of amino acids.
Today we begin our discussion of the structure and properties of proteins. Proteins consist in whole or large part of amino acids. Simple proteins consist only of amino acids. Conjugated proteins contain
Proteins are sometimes only produced in one cell type or cell compartment (brain has 15,000 expressed proteins, gut has 2,000).
