peptide linkage is a type of amide linkage which is found in a protein chain.The bond is between the two consecutive Alpha amino acids.
Enzymes which catalyze the reaction in a human body are called Biocatalysts.They also contain some protein parts in their structure. e.g-pepsin.
Final Answer:-
Amide linkage between the two consecutive acids in the protein chain is called peptide linkage.
Biocatalysts catalyze human body reactions.
