How many different tripeptides can be formed using only glutamine and leucine?
How many different tripeptides can be formed using only glutamine and leucine?
If the sequences are QQQ, QQL, QLL, LLL, QLQ, LQL, LLQ, and LQQ
wouldn't LLQ & QLL be the same since it's just the same peptide chain flipped?
LLQ and QLL will be different since in LLQ the first L will have a free NH2 group and the Q will have a free COOH group.
In QLL the Q will have a free NH2 group and the last L will have a free COOH group.
So they are different and you get a total of 8 different tripeptides.
