How are these formed and how do they work ? Types of Acids: The substances which have the ability to protonate other compounds are primarily considered acids. Acids are of different types depending upon chemical nature, such as mineral acids, carboxylic acids, Lewis acids, peroxy acids, superac...
Through a series of experiments, researchers were able to demonstrate how solar particles colliding with gases like carbon dioxide, molecular nitrogen and methane could produce amino acids and carboxylic acids — fundamental components of proteins and organic life. To better understand how life began, ...

Acetic anhydride, orethanoic anhydride, is the chemical compound (CH3CO)2O. Commonly abbreviated Ac2O, it is the simplest isolable anhydride of a carboxylic acid and is widely used as a reagent in organic synthesis. It is a colorless liquid that smells strongly of acetic acid, formed by its...
(Schmidt and McDonald1979a; Surdam et al.1989; Surdam and Boese1984), carboxylic acids generated during the thermal maturation of organic matter (Surdam et al.1989; Surdam and Boese1984), acidic fluids generated by clay mineral reactions (Giles and Marshall1986), acid fluids generated by ...
SpyRing cyclization occurs through reaction of an amine with a carboxylic acid with release of water, but both SnoopRing and PilinRing cyclization occur through reaction of an amine with a carbox- amide with release of ammonia (Fig. 1A)20,22. Cyclization was evaluated by the change in ...

While oxygen-based alcohols generally oxidize to form aldehydes and carboxylic acids, thiols can oxidize in TWO different ways--- losing a hydrogen or gaining an oxygen each give surprisingly different paths. ... That eventually formsa sulfinic acid and then a sulfonic acid. ...
