Propyl propanoate (also known as propyl propionate and n-propyl propionate) is the organic compound with the molecular formula C 6 H 12 O 2. It is the ester of propanol and propionic acid. Like most esters, propyl propanoate is a colorless liquid with a fruity odor. The scent of propyl propionate is described as a chemically tinged pineapple or ...
Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate is significantly less volatile than simpler phenolic antioxidants such as butylhydroxytoluene (BHT). This makes it more suitable to stabilising plastics, as it is not driven out by the high temperatures experienced during plastic extrusion and moulding, [2] when they are heated to 150-320 °C (300–600 °F). [3]
As a food additive, it is approved for use in the EU, [23] US, [24] Australia and New Zealand. [25] Propionic acid is also useful as an intermediate in the production of other chemicals, especially polymers. Cellulose-acetate-propionate is a useful thermoplastic. Vinyl propionate is also used.
Propionyl-CoA is a coenzyme A derivative of propionic acid.It is composed of a 24 total carbon chain (without the coenzyme, it is a 3 carbon structure) and its production and metabolic fate depend on which organism it is present in. [1] Several different pathways can lead to its production, such as through the catabolism of specific amino acids or the oxidation of odd-chain fatty acids. [2]
It is used in several products, which include: fertilizers, water treatment chemicals, and plant protection products. It is also used in different areas, such as: manufacturing, forestry, agriculture, and fishing. [1] It also serves as an antiseptic, antifungal agent, antimould agent, and preservative in feed industry or food industry. [2]
In enzymology, a propionate CoA-transferase (EC 2.8.3.1) is an enzyme that catalyzes the chemical reaction. acetyl-CoA + propanoate acetate + propanoyl-CoA. Thus, the two substrates of this enzyme are acetyl-CoA and propanoate, whereas its two products are acetate and propanoyl-CoA.
1-Propanol (also propan-1-ol, propanol, n-propyl alcohol) is a primary alcohol with the formula CH 3 CH 2 CH 2 OH and sometimes represented as PrOH or n-PrOH.It is a colourless liquid and an isomer of 2-propanol. 1-Propanol is used as a solvent in the pharmaceutical industry, mainly for resins and cellulose esters, and, sometimes, as a disinfecting agent.
In enzymology, a propionate—CoA ligase (EC 6.2.1.17) is an enzyme that catalyzes the chemical reaction. ATP + propanoate + CoA AMP + diphosphate + propanoyl-CoA. The 3 substrates of this enzyme are ATP, propanoate, and CoA, whereas its 3 products are AMP, diphosphate, and propanoyl-CoA.
