Essentially, peptides are short molecules formed by linkage of amino acids. Protiens

are long molecules formed by linkage of amino acids.

Hence you don't have proteins in

peptides.
Gentlemen,
Having been acused on several occassions of getting "too technical," I

suspect we may be pressing the upper limits of technicalities here, but also wanted to add:

From Wikpedia:

(because even I had to check my assumptions)
"a peptide is an amino acid molecule without secondary structure; on

gaining defined structure, it is a protein." Thus the same molecule can be either a peptide or a protein depending

on its environment, though there are peptides that cannot be

proteins."
