Carboxylic in a sentence

Smaller carboxylic acids (1 to 5 carbons) are soluble in water, whereas higher carboxylic acids are less soluble due to the increasing hydrophobic nature of the alkyl chain.

The carboxylic acids were the result of the secretion of sebum, an oily substance that protects the skin.

Acidic conditions yield the carboxylic acid and the ammonium ion while basic hydrolysis yield the carboxylate ion and ammonia.

Acidity Carboxylic acids are Brønsted–Lowry acids because they are proton (H + ) donors.

Ammonium salts of carboxylic acids can be dehydrated to amides so long as there are no thermally sensitive groups present: temperatures of 150–200 °C are required.

An amino acid contains both acidic (carboxylic acid fragment) and basic (amine fragment) centres.

An α-amino acid has a central carbon (the α or alpha carbon ) which is covalently bonded to a carboxyl group (thus they are carboxylic acids ), an amino group, a hydrogen atom and a variable group.

As a bicyclic, heterocyclic purine derivative, uric acid does not protonate as an oxygen (−OH) like carboxylic acids do.

Aspirin (acetylsalicylic acid) is a carboxylic acid Cell membranes are generally impermeable to charged or large, polar molecules because of the lipophilic fatty acyl chains comprising their interior.

Because all amino acids contain amine and carboxylic acid functional groups, they share amphiprotic properties.

Below pH 2.2, the predominant form will have a neutral carboxylic acid group and a positive α-ammonium ion (net charge +1), and above pH 9.4, a negative carboxylate and neutral α-amino group (net charge −1).

Bromine, sometimes with phosphorus as a catalyst, easily brominates carboxylic acids at the α-position.

Carboxyl group All the reactions mentioned for carboxylic acids are also possible for benzoic acid.

Carboxylic acids are used in the production of polymers, pharmaceuticals, solvents, and food additives.

Carboxylic acids can be seen as reduced or alkylated forms of the Lewis acid carbon dioxide ; under some circumstances they can be decarboxylated to yield carbon dioxide.

Carboxylic acids occur widely and include the amino acids (which make up proteins ) and acetic acid (which is part of vinegar and occurs in metabolism ).

Consequently, esters are more volatile than carboxylic acids of similar molecular weight.

DCC ( dicyclohexylcarbodiimide ) is used to activate the carboxylic acid to further reaction.

Following the same rules, the carboxylic acid carbon atom gets the other one valence electron from the C−C bond.

Humans lack the ability to introduce double bonds in fatty acids beyond carbons 9 and 10, as counted from the carboxylic acid side. citation Two essential fatty acids are linoleic acid (LA) and alpha-linolenic acid (ALA).
