Question

Quizplus · Accepted Answer

Secondary metabolites are compounds that are not essential for growth or survival of the plant, but rather serve other functions such as defense against herbivores or pathogens. While some secondary metabolites may contain amino acids, they are not typically ones that are normally part of proteins. Rather, they are often modified or have additional functional groups added to make them more effective in their particular role.
