Proteins

• Proteins are polymers made of amino acid monomers
• R is a placeholder for other atoms or molecules
• The carbon in the middle is called the alpha carbon
• The carboxyl groups acts as an acid and donated a proton
• The amino group acts as a base and receives a proton
• R groups can be complicated or simple
• Amino acids are categorized based on their R groups
• Macromolecules are large molecules made of smaller subunits
• Peptide bonds are bonds between 2 amino acids
• Two molecules bonded by a peptide bond can be called a dipeptide
• Amino terminus is the amino group on the end
• Carboxyl terminus is the carboxyl group on the end
• All amino acids are added onto the C term
• Side chains alternate sides
• Proteins are used for structure, transport, catalyzing chemical reactions and defense
