Following two amino acids lysine and glutamine form dipeptide linkage. What are two possible dipeptides ?
`{:(H_(2)N-CH-COOH" "H_(2)N-CH-COOH),(" | |"),(" "CH_(2)CH_(2)CH_(2)CH_(2)NH_(2)" "CH_(2)CH_(2)COOH):}`

Answer

Peptide linkage is `-NH - overset(overset(O)(||))(C)-` and it is formed by the condensation between `-NH_(2)` group and `-COOH` groups as follows
`(##RES_ORG_CHM_V02_XII_C04_E01_166_A01##)`
`(##RES_ORG_CHM_V02_XII_C04_E01_166_A02##)`
`(##RES_ORG_CHM_V02_XII_C04_E01_166_A03##)`.

Explanation

Peptide linakage is `-NH-overset(overset(O)(||))(C)-` and it formed by the condensation between `-NH_(2)` group and `-COOH` groups as follows
