How many different tripeptides can be formed using only glutamine and leucine?
January 31st, 2010 | by admin |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.
