Propionaldehyde
Propionaldehyde, also known as propanal, is the three-carbon saturated aldehyde, a clear, flammable liquid boiling at 49 °C and used industrially almost entirely as a reactive intermediate.
Propionibacterium
Propionibacterium is a genus of gram-positive, rod-shaped, anaerobic bacteria named for the propionic acid they produce by fermentation, found on human skin and in dairy products and used as starter cultures in Swiss-type cheese.
Propionibacterium acnes
Propionibacterium acnes, renamed Cutibacterium acnes in 2016, is a Gram-positive anaerobic rod dominant in human sebaceous skin, a commensal and acne-associated bacterium with phylotypes IA1, IB, II, III and rising antibiotic resistance.
Propionibacterium-cultured dextrose and skim milk
Propionibacterium-cultured dextrose and skim milk (Microgard, MicroGARD) are P. freudenreichii subsp. shermanii fermentates used as antimicrobial food preservatives, GRAS via FDA GRN 128 (2003) at up to 2% in foods.
Propionic acid
Propionic acid, also called propanoic acid, is a three-carbon carboxylic acid, a colorless, oily liquid with a pungent odor produced industrially and used chiefly as a food and feed preservative.
Propionic acidemia
Propionic acidemia (PA), also called propionyl-CoA carboxylase deficiency, is a rare autosomal recessive metabolic disorder from PCCA or PCCB mutations, causing neonatal metabolic acidosis, hyperammonemia, cardiomyopathy, and neurological damage.
Propionic anhydride
Propionic anhydride (propanoic anhydride) is the symmetrical acid anhydride of propionic acid, a colorless, water-reactive liquid used chiefly as an acylating agent to make cellulose propionate and other propionate esters.
Propionitrile
Propionitrile (propanenitrile, ethyl cyanide) is a colorless, flammable three-carbon nitrile used as a polar aprotic solvent and chemical intermediate; the body metabolizes it to release cyanide.
Propionyl-CoA
Propionyl-CoA (propanoyl-CoA), a three-carbon acyl-CoA thioester from amino acid and odd-chain fatty acid catabolism, is carboxylated by biotin-dependent PCC to methylmalonyl-CoA and succinyl-CoA; PCC deficiency causes propionic acidemia.
