The observation side chain of the 20 amino acids commonly found in proteins did not contain either aldehyde or a ketone carbonyl group is to be explained. If present what complications such an aldehyde or ketone may give also is to be stated. Concept introduction: The formation and the functions of proteins are based on the sequence in which the amino acid molecules are arranged in the polypeptide chain. If both electrophilic and nucleophilic groups are present in the same amino acid molecule then an internal reaction may occur between these two groups. As a result the formation of the peptide chain is disturbed and even terminated resulting in the malfunctioning of the proteins. To explain: The observation side chain of the 20 amino acids commonly found in proteins did not contain either aldehyde or a ketone carbonyl group and further to state, if present, what complications such an aldehyde or ketone may give.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.
