Alanine with a three (3) letter code of Ala, single letter code of A and a molecular formula of C3H7NO2.Glycine with a three (3) letter code of Gly, single letter code of G and a molecular formula of C2H5NO2.Listed below are the aforementioned amino acids: Amino Acids with Nonpolar side chains These three (3) major types of functional groups have a number of amino acids per classification or type. Side chains with a negative charge such as aspartic acid and glutamic acid, tend to be acidic. Amino acid side chains can also have a specific charge and those with a positive charge tend to be basic such as arginine, histidine and lysine. Amino Acids that have electrically charged side chainsĪs mentioned earlier, amino acids can generally be either positively charged, negatively charged or neutral/ uncharged. Amino acids that are positively charged tend to be more basic while negatively charged amino acids tend to be more on the acidic side. These are amino acids or organic compounds that can identified as either positively or negatively charged. Nonpolar amino acids are hydrophobic which means they do not tend to move or combine with other aqueous compounds. These are amino acids or organic compounds that have no “charge” on the R group. There are three (3) Major types of Functional Groups based on the R group of the said amino acid. Types of “R” or Amino Acid Functional Groups These amino acids will have their functional groups and their unique properties composed of molecular structures that may be as simple as hydrogen or as large as a circular molecular structure. This design and structure comprises what is called an amino acid. These functional groups are in turn, connected to a carbon atom and to the right and left of this carbon atom, also identified as the backbone of the amino acid, are the carboxylic acid (COOH) and amine group (NH2). This specific placeholder serves as an indicator where the functional group will be located. The molecular structure of these functional groups are usually represented by the placeholder labeled “R”. What are amino acid functional groups?Īs briefly discussed earlier, amino acid functional groups determine the type or class of amino acid present. In this article we will look at the different amino acid functional groups. These different types or classifications of amino acids are determined by their specific functional groups and these functional groups gives the amino acids their unique properties such as being polar, aromatic, charged or aliphatic. Amino acids can be classified based on a number of different types and classifications.
Amino acids are the building blocks of proteins and thus, are very important for the overall health and survival of an individual.
