Question: Identify the type of bond formed when the amino group of alanine reacts with the carboxylic acid group of glycine, and write the structural formula of the resulting dipeptide. Step 1: Recall the structure of alanine (R group is -CH3) and glycine (R group is -H). Both possess an amino group (-NH2) and a carboxylic acid group (-COOH). Step 2: Understand that a peptide bond forms via a condensation reaction where a water molecule (H2O) is removed. The -OH from the carboxyl group of glycine combines with a hydrogen (-H) from the amino group of alanine. Step 3: Connect the remaining carbonyl carbon of glycine to the nitrogen of alanine's amino group. The resulting chemical formula for the glycyl-alanine dipeptide is H2N-CH2-CO-NH-CH(CH3)-COOH.
