Answer:
a substance occurring as an intermediate or final product in the life processes of organisms. This term is arbitrary since it does not include a number of simple metabolic products (methane, acetic acid, ethyl alcohol), certain components of coals and petroleum, and inorganic compounds that are either formed in metabolic processes (O2, CO2, H2O) or are present in the inorganic world (minerals, gases). A distinction is made between high-molecular-weight natural compounds, for example, biopolymers, and low-molecular-weight natural compounds; the arbitrary boundary between the two lies in the vicinity of a molecular weight of 5,000 daltons. High-molecular-weight natural compounds include proteins, nucleic acids, and polysaccharides, as well as such composite biopolymers as glycoproteins, nucleoproteins, and lipoproteins. These substances are cells, and they carry out extremely important biological functions (biological catalysis, storage and transmission of genetic information, transport of substances, immunity). Polyisoprenoids, another type of biopolymer, are found in some plants, such as plants yielding rubber and gutta-percha. Low-molecular-weight natural compounds include a large number of organic compounds of different chemical nature. This category encompasses monomeric components of biopolymers (amino acids, nucleotides, monosaccharides), compounds constructed of a small number of monomeric units (oligonucleotides, oligosaccharides), and lipids, as well as a large number of aliphatic, alicyclic, aromatic, and heterocyclic organic compounds (natural pigments, steroids, iso-prenoids, alkaloids). In organisms, low-molecular-weight natural compounds serve as structural materials in the synthesis of biopolymers, agents having specific biological regulatory effects (hormones, mediators, vitamins), and protective agents (toxins, antibiotics). They also figure in the communication between organisms through such chemical substances as pheromones.
