Question
A tipeptide on complete hydrolysis give glycine, alanine and phenyl alanine. Using three letter symbols, write down the possible sequences of the tripeptide.
Solution
A tripeptide is a peptide obtained by the condensation of three amino acids. The possible combinations of tripeptide obtained from glycine, alanine and phenylalanine are:
(i) Gly-Ala-Phe
(ii) Gly-Phe-Ala
(iii) Ala-Gly-Phe
(iv) Ala-Phe-Gly
(v) Phe-Ala-Gly
