Amino acids are defined as simple organic compounds that contain which two
functional groups? Carboxyl (—COOH) and Amine (—NH₂)
What functional group is described as a basic nitrogen atom with a lone pair
of electrons? Amine
An amide functional group is characterized by a carbonyl group linked to
which other atom? Nitrogen
The formation of a peptide bond is a condensation reaction in which the
N-terminus of one amino acid nucleophilically attacks the C-terminus of
another. This reaction involves the elimination of which molecule? Water (H₂O)
Rotation around the C–N bond in a peptide linkage is restricted due to: Resonance, which gives the bond a partial double bond character
Proteins are best described as large, folded, functional molecules made up
of multiple amino acids linked by: Peptide bonds
Which of the following classes of compounds are hydrocarbon compounds
containing carbon and hydrogen joined together in straight chains, branched
chains, or non-aromatic rings? Aliphatic compounds
Which laboratory synthesis method generates an amino acid starting from an
aldehyde? Strecker synthesis
Which of the following reagents is required for the Gabriel synthesis of an
amino acid? Potassium phthalimide
Which statement is TRUE regarding peptide bonds? They can be cleaved hydrolytically using a strong acid or base
