Which of the following organic families contain the carbonyl carbon?AldehydeEtherCarboxylic acidAlkeneAmideAmine
In the following structure, consider the amide group- highlighted green- which contains a peptide bond: In the structure below, convert the peptide bond-containing amide group into an analog that could be a likely transitionstate analog. Include hydrogen atoms on non-carbon atoms. Hint: Modify the given structure to generate your response. Correct answers conatin a single-chain "peptide", do not divide the structure into fragments. Consider an analog with a reduced group or a carbon atom replacing the nitrogen atom. Do not...
