The esters of propionic acid have fruit-like odors and are sometimes used as solvents or artificial flavorings. [15] In biogas plants, propionic acid is a common intermediate product, which is formed by fermentation with propionic acid bacteria. Its degradation in anaerobic environments (e.g. biogas plants) requires the activity of complex ...
Acetic acid: Ethanoic acid Acetate: Ethanoate C 2 H 4 O 2: CH 3 COOH: 60.05 C3:0 Propionic acid: Propanoic acid Propionate: Propanoate C 3 H 6 O 2: CH 3 CH 2 COOH: 74.08 C4:0 Butyric acid: Butanoic acid Butyrate: Butanoate C 4 H 8 O 2: CH 3 (CH 2) 2 COOH: 88.11 C4:0 Isobutyric acid: 2-Methylpropanoic acid Isobutyrate: 2-Methylpropanoate C 4 H 8 ...
Ibuprofen was derived from propionic acid by the research arm of Boots Group during the 1960s. [73] The name is derived from the 3 functional groups: isobutyl (ibu) propionic acid (pro) phenyl (fen). [74] Its discovery was the result of research during the 1950s and 1960s to find a safer alternative to aspirin.
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
It is composed of four pyrrole rings with 2 vinyl and 2 propionic acid side chains. [1] Heme is biosynthesized in both the bone marrow and the liver. [2] Heme plays a critical role in multiple different redox reactions in mammals, due to its ability to carry the oxygen molecule.
Certain bacteria form close spatial associations that are essential for their survival. One such mutualistic association, called interspecies hydrogen transfer, occurs between clusters of anaerobic bacteria that consume organic acids, such as butyric acid or propionic acid, and produce hydrogen, and methanogenic archaea that consume hydrogen.

In many cases, propionic acidemia can damage the brain, heart, kidney, liver, cause seizures and delays to normal development such as walking or talking. The accumulation of propionic acid is known to induce differential responses in different organs. The heart and liver are specific targets of the complication.
