A. Definition of Natural Products
Natural products are organic compounds that are synthesized
by living organisms.
These compounds are typically produced by plants,
microorganisms, and animals through various biochemical pathways. charcoalsoap4
They are characterized by their origin from biological
sources and often exhibit complex chemical structures.
Natural products can range from simple molecules like sugars
and amino acids to highly intricate compounds like alkaloids and polyketides.
Natural products are distinct from synthetic chemicals,
which are created through chemical processes in laboratories.
Examples of natural products include:
Alkaloids such as caffeine and morphine from plants.
Antibiotics like penicillin from fungi.
Secondary metabolites like flavonoids in fruits and
vegetables.
Natural products can have a wide range of biological
activities, including pharmacological, antimicrobial, antioxidant, and
anti-inflammatory properties.
They play a crucial role in various fields, including
medicine, agriculture, food science, and cosmetics, due to their diverse and
valuable properties.
The study of natural products involves their isolation,
characterization, and exploration of their potential applications in different
industries, making it a multidisciplinary field at the intersection of
chemistry, biology, and pharmacology.
