Study Notes
Primary and Secondary Metabolites
- Alkaloids, such as caffeine and nicotine, are not primary metabolites of plants
- Primary metabolites are essential for plant growth and development, while secondary metabolites are not directly involved in these processes
- Secondary metabolites have a limited distribution in the plant kingdom, often being specific to a particular plant family or genus
Secondary Metabolites
- Terpenes, alkaloids, and phenolics are examples of secondary metabolites
- Terpenes are often strong-smelling, such as those found in the oils of citrus and coniferous trees
Terpenes
- The biosynthetic origin of terpenes is from the mevalonic acid pathway
- Functions of terpenes include:
- Defending against herbivores and pathogens
- Attracting pollinators and other beneficial organisms
- Providing fragrance and flavor to plants
- Playing a role in plant growth and development
