The peptide linkage is the amide bond ($-\text{CO}-\text{NH}-$) formed between the carboxyl group of glycine and the amino group of alanine with elimination of a water molecule:
$\text{H}_2\text{N}-\text{CH}_2-\text{CO}-\text{NH}-\text{CH}(\text{CH}_3)-\text{COOH} + \text{H}_2\text{O}$
The characteristic linkage is:
$-\text{C}(=\text{O})-\text{NH}-$
