a dipeptide consists of 2 amino acids joined by a peptide bond. dipeptides may differ in the type of amino acids they contain.
describe 2 other ways in which all dipeptides are similar and one way in which they might differ. [3 marks]

I am struggling to think of things of the top of my head, but possibly
Similarities:
- The peptide bonds in all amino acids are formed through condensation reactions (They all lose a water molecule)
- All dipeptides contain at least 2 Nitrogen atoms/4 Carbon atoms/3 Oxygen atoms/6 Hydrogen atoms ( a long shot i know but all else I can think of)
Difference:
- Each dipeptide will have a different number of carbon atoms (coming from the variable region)

Similarities; All dipeptides contain carbon, hydrogen, nitrogen and oxygen (sometimes sulfur) / All dipeptides formed from a condensation reaction of 2 amino acids, joined by a peptide bond (although given in question stem)
Differences; Different R groups
