Malonate resembles succinate in structure. Succinate is the substrate of the enzyme succinate dehydrogenase. Hence, malonate acts as an inhibitor of succinate dehydrogenase enzyme.

Collagen is a structural protein. Protein is made up of amino acids through peptide bonds and hence, collagen has peptide bonds.

Cell wall of fungi is made of chitin. Chitin is a polysaccharide.

Ricin, a toxin is a secondary metabolite. Secondary metabolites are biological products which are not directly involved in growth and development of the organisms.
