Tripeptides among amino acids?
If there is a "soup" containing serine, aspartic acid, and lysine, how many possible combinations of tripeptides could be obtained?
I'm not sure how I would figure this out? Could you please explain?

The number of possible combination of the tripeptide is six and its calculation has tn do with a mathematical term called factorial. Since it is 3 different proteins, the number of ways they could be arranged will be 3 factorial=3*2*1=6(4 factorial will be 4*3*2*1 and so on).
The six combinations are
Serine, aspartic acid and lysine
Serine, lysine and aspartic acid
Lysine, serine and aspartic acid
Lysine, aspartic acid and serind
Aspartic acid, serine and lysine
Aspartic acid, lysine and serine.
There are 4 tripeptide combos possible for 4 aminoacids, yet on condition which you do no longer count quantity the comparable amino acids in diverse order as a various tripeptide, wherein case may well be a extensive quantity.
