Carboxylate ion Acrylate ion. In organic chemistry, a carboxylate is the conjugate base of a carboxylic acid, RCOO − (or RCO − 2). It is an anion, an ion with negative charge. Carboxylate salts are salts that have the general formula M(RCOO) n, where M is a metal and n is 1, 2,....
An ester of a carboxylic acid.R stands for any group (typically hydrogen or organyl) and R ′ stands for any organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (R ′). [1]
It is known that the reactivity of the monomer is lower than it could be, since the contained ester group can react with the reactive, polymerizing chain end and stabilize it. It therefore reacts significantly slower than other molecules without ester group. [2] [6] ECC polymerizes also much slower than radical monomers. It is therefore the ...
Cholesteryl oleate, a member of the cholesteryl ester family. Cholesteryl esters are a type of dietary lipid and are ester derivatives of cholesterol. The ester bond is formed between the carboxylate group of a fatty acid and the hydroxyl group of cholesterol. Cholesteryl esters have a lower solubility in water due to their increased ...

"I didn't find the scent overpowering, but I wouldn't say it's entirely free of cleaner scents, either" As for application, just use a damp cloth or sponge to gently buff away the stain.
Structure of a carboxylic acid Carboxylate anion 3D structure of a carboxylic acid. In organic chemistry, a carboxylic acid is an organic acid that contains a carboxyl group (−C(=O)−OH) [1] attached to an R-group.
"The Quick and the Dead" has the heart of a classic Western, but revamped for modern audiences with snappier taste." [50] Film critic Adrian Martin remarked, "Sam Raimi's The Quick and the Dead is a feminist Western starring a gun-toting Sharon Stone. [There is] a terrific scene where Lady goes berserk and challenges a guy who has just sexually ...
