Acid Reflux or Gastroesophageal Reflux Disease (GERD) is caused by stomach acid rise towards the esophagus and cause pain in the solar plexus or a burning sensation in the chest. The cause of acid reflux (GERD) is the proper functioning of the lower esophageal sphincter (LES). LES is a circle of muscle at the bottom of the esophagus. LES serves as the automatic door opens when food or drink down to the stomach. After the food came in‚ the LES will be shut down to prevent the existing food and acid

What is acetylsalicylic acid? Acetylsalicylic acid (ASA)‚ or more commonly known as aspirin‚ is a medication that can be used for pain‚ fevers‚ and inflammation. It can be used for long periods of time‚ in small amounts‚ to prevent heart attacks‚ strokes and the formation of blood clots.

Amino acids are the building blocks of proteins. They band together in chains to form the stuff from which your life is born. Think of amino acids as Legos for your life. It’s a two-step process: Amino acids get together and form peptides or polypeptides. It is from these groupings that proteins are made. And there’s not just one kind of amino acid. A total of 20 different kinds of amino acids form proteins. The kinds of amino acids determine the shape of the proteins formed. Commonly recognized

Carboxylic acids are compounds which contain a carboxyl group‚ -COOH group‚ where the -COOH group is attached either to a hydrogen atom or to an alkyl group. One of the example of carboxylic acid is benzoic acid( benzene carboxylic acid) which has a benzene connected to the carboxyl carboxyl group‚ -COOH group. It has a formula of C6H5COOH. The carbon atom of a carboxyl group has a high oxidation state. Therefore‚ that many of the chemical reactions used for their preparation are oxidations. In
