An Example of a pH scale is located above. A pH scale | An Example of a pH scale is located above. A pH scale ranges from 1-14, 1 being the most acidic and 14 being the most basic. An acidic pH has a value below 7, a basic pH is greater than 7, and a pH of 7 is considered neutral (ex: water). Some common acidic functional groups are alcohols (OH) and carboxylic acids (COOH). Some basic functional groups are amines (NH3) and ethers (CH2OCH2). | ||
You can predict if an amino acid will be acidic or basic according to its structure. For example, <scene name='Tutorial:Basic_Chemistry_Topics/Glu/1'>glutamic acid</scene> contains a carboxylic acid functional group, which was stated previously to be an acidic functional group that lowers the pH of the amino acid. On the other hand, <scene name='Tutorial:Basic_Chemistry_Topics/arginine/1'>Arginine</scene> is classified as a basic amino acid. The functional group of arginine contains a guanidine group. A guanidine group contains amine groups, increasing the pH of the amino acid. | |||
