Acetic acid / ə ˈ s iː t ɪ k /, systematically named ethanoic acid / ˌ ɛ θ ə ˈ n oʊ ɪ k /, is an acidic, colourless liquid and organic compound with the chemical formula CH 3 COOH (also written as CH 3 CO 2 H, C 2 H 4 O 2, or HC 2 H 3 O 2). Vinegar is at least 4% acetic acid by volume, making acetic acid the main component of vinegar ...
NAA is a synthetic plant hormone in the auxin family and is an ingredient in many commercial horticultural products; it is a rooting agent and used for the vegetative propagation of plants from stem and leaf cuttings. It is also used for plant tissue culture. [2]
Juglone is an example of such a molecule inhibiting the growth of other plant species around walnut trees. [citation needed] The aquatic vascular plant Myriophyllum spicatum produces ellagic, gallic and pyrogallic acids and (+)-catechin, allelopathic phenolic compounds inhibiting the growth of blue-green alga Microcystis aeruginosa.

The acid-growth hypothesis is a theory that explains the expansion dynamics of cells and organs in plants. It was originally proposed by Achim Hager and Robert Cleland in 1971. [1] [2] They hypothesized that the naturally occurring plant hormone, auxin (indole-3-acetic acid, IAA), induces H + proton extrusion into the apoplast.
The most important member of the auxin family is indole-3-acetic acid (IAA), [7] which generates the majority of auxin effects in intact plants, and is the most potent native auxin. And as native auxin, its equilibrium is controlled in many ways in plants, from synthesis, through possible conjugation to degradation of its molecules, always ...
Its Nevinnomysskiy Nitrogen plant in southwest Russia has sent at least 38,000 metric tons of acetic acid to Sverdlov during the Ukraine war, according to a Reuters analysis of the railway data.
Indole-3-acetic acid (IAA, 3-IAA) is the most common naturally occurring plant hormone of the auxin class. It is the best known of the auxins, and has been the subject of extensive studies by plant physiologists. [1] IAA is a derivative of indole, containing a carboxymethyl substituent. It is a colorless solid that is soluble in polar organic ...
Cellulose is a carbohydrate, specifically a polysaccharide, which can be found in the cell walls of plants, algae, fungi, and some bacteria. Through its production of acetic acid and oxidation of ethanol, A. aceti plays a crucial role in synthesis of bacterial cellulose. Bacterial cellulose is unique from plant cellulose due to its highly pure ...
