Morphology

dipeptide = peptide (transparent) = di + peptide

The combining prefix 'di-' (two) added to the noun 'peptide' yields a literal, compositional meaning 'two-peptide' (i.e., a molecule made of two amino acids), which is a standard productive formation in scientific vocabulary.

Etymology

The word dipeptide breaks into di- meaning 'two' and peptide meaning 'a small piece of a protein', so a dipeptide is simply two amino acids joined together.
