Propionic acid (C3H6O2) is an endogenous liquid with an average molecular weight of 74.08 g/mol. Propionic acid belongs to the carboxylic acids, a subclass of carboxylic acids and derivatives within the organic compounds. In industrial applications, it is utilized as a preservative, biocide, additive, solvent, fragrance, pH regulating agent, and as a flavouring and nutrient (PMC13004434 ). It is used in Low-Density Polyethylene and High-Density Polyethylene, and it is released in Polypropylene, though its use in Poly(methyl methacrylate) and Ethylene-vinyl acetate is inconclusive.
The compound is detected in several tissues, including the brain, intestine, muscle, adipose tissue, epidermis, stratum corneum, fibroblasts, neuron, platelet, and testes. It has three recorded protein targets: 2-hydroxy-6-oxo-7-methylocta-2,4-dienoate hydrolase (cumD), alanine racemase (alr), and gephyrin (GPHN). Propionic acid is found in or released from 54 recorded sources across various sectors, including healthcare, pharmaceuticals & veterinary products (antiinfectives); drinking water & water supply (drinking water); household cleaning & consumer products (perfumes within detergents and soaps, bleaching agents, cigar cigarettes, other smoking requisites, and non electric simulated smoking devices); food, food processing & cookware (food preservation, fermentation processes for beer, food contact materials, preparation of malt, and cellar tools); building & construction (floors, ceilings, fencing, stairs and ramps, and ladders); and electrical & electronic equipment (amplifiers, antennas, auxiliary devices, communication cables or conductors, and coils). Recorded exposure routes include oral, inhalation, touch, and vaginal. Regarding health effects, propionic acid has a therapeutic effect on osteoporosis (PMC13299190 ) and is associated with an increase in obesity (PMC11995813 ).
Belongs to the class of organic compounds known as carboxylic acids. Carboxylic acids are compounds containing a carboxylic acid group with the formula -C(=O)OH.
In healthy individuals, the enzyme propionyl CoA carboxylase converts propionyl CoA to methylmalonyl CoA. This is one step in the process of converting certain amino acids and fats into sugar for energy. Individuals with propionic acidemia cannot perform this conversion because the enzyme propionyl CoA carboxylase is nonfunctional. The essential amino acids; isoleucine, valine, threonine, and methionine and odd-chain fatty acids are simply converted to propionyl CoA, before the process stops, leading to a buildup of propionyl CoA. Instead of being converted to methylmalonyl CoA, propionyl CoA is then converted into propionic acid, which builds up in the bloodstream. Propionyl-CoA, propionic acid, ketones, ammonia, and other toxic compounds accumulate in the blood, causing the signs and symptoms of propionic acidemia. Propionate acts as a metabolic toxin in liver cells by accumulating in mitochondria. Propanoate is metabolized oxidatively by glia, which suggests astrocytic vulnerability in propanoic acidemia when intramitochondrial propionyl-CoA may accumulate. Propanoic acidemia may alter both neuronal and glial gene expression by affecting histone acetylation (22, 23). (Wikipedia)

Symptoms
Propionic acidemia is characterized almost immediately in newborns. Symptoms include poor feeding, vomiting, dehydration, acidosis, low muscle tone (hypotonia), seizures, and lethargy. The effects of propionic acidemia quickly become life-threatening. (Wikipedia)
Treatment
During times of illness the affected person may need to be hospitalized to prevent breakdown of proteins within the body. Each meal presents a challenge to those with propionic acidemia. If not constantly monitored, the effects would be devastating. Dietary needs must be closely managed by a metabolic geneticist or metabolic dietician. Patients with propionic acidemia should be started as early as possible on a low protein diet. In addition to a protein mixture that is devoid of methionine, threonine, valine, and isoleucine, the patient should also receive L-carnitine treatment and should be given antibiotics 10 days per month in order to remove the intestinal propiogenic flora. The patient should have diet protocols prepared for him with a “well day diet” with low protein content, a “half emergency diet” containing half of the protein requirements, and an “emergency diet” with no protein content. These patients are under the risk of severe hyperammonemia during infections that can lead to comatose states. Liver transplant is gaining a role in the management of these patients, with small series showing improved quality of life. (Wikipedia)
