In conjugated protein molecules, the protein is attached or conjugated to some non-protein group which are called:

Explanation

Explanation:In conjugated protein molecules, the protein is attached or conjugated to some non-protein group which is called prosthetic group. Hydrogen bonding is not related to conjugated proteins. Hydrogen bonding is a type of intermolecular force that occurs between a hydrogen atom and in one molecule and an electronegative atom (such as oxygen, nitrogen, or flourine) in another molecule.Aldehyde group is a functional group that contains a carbon atom double-bonded to an oxygen atom and single bonded to a hydrogen atom or another group. Aldehyde groups are not typically found in prosthetic groups of conjugated proteins. Peptide linkage refers to the covalent bond between two amino acids in a protein molecule. While peptide linkages are important for the structure and function of proteins, they are not considered prosthetic groups in conjugated proteins.
