If three amino acids are combined, how many peptide linkages will be there and what will be the product?

A carbohydrate "A" containing 42.1% C and 6.4% H does not show any reducing property.
On hydrolysis with dil. HCl, a mixture of two isomeric substances "B" and "C" each containing 40% C and 6.67% H are produced.
''B'' reduces Fehling's solution and produces a yellow crystalline compound with excess phenylhydrazine.
''C'' does not reduce Fehling's solution but produces the same yellow crystalline solid with excess phenylhydrazine.
