Some of their crucial roles are listed as follows: The roles played by the functional group phosphate are responsible for varying reactions in living organisms. For example, Methyl functional group is represented as R-CH3. Generally, function groups are represented along with the R symbol to represent the rest of the molecule other than the functional group. Further, this bond also plays its role in the process of recognition in cases such as the pairing of DNA and the enzyme binding to the respective substrates. The bonds of hydrogen are important for any molecules for appropriate structure formation and folding. The Phosphate, Carbonyl, Hydroxyl, Methyl, Carboxyl, Sulfhydryl Groups, and Amino are a few of the crucial function groups in biological organisms. The nonpolar molecule of methane is an example of a hydrophobic molecule whereas the carboxyl group in certain amino acids or fatty acids that is involved in the formation of phospholipids and triglycerides comes under the category of hydrophilic groups. These are categorized as hydrophilic or hydrophobic groups based on their polarity charge. This group plays a significant role by connecting with the molecule that has carbon as its backbone. Thus it has a hugely significant role in the environment and living beings. Phospholipids that make up the membrane of the cell is created with the phosphate group. This particular group is present in Ribonucleic acid (RNA), Deoxyribonucleic acid (DNA), Adenosine Triphosphate (ATP). This is called a phosphate group when they are connected with the molecule that contains carbon. As the formula states, it is made up of 1 phosphorus and 4 atoms of oxygen. Phosphate is represented with a formula of chemistry as PO43. Phosphate functional groups are one of the significant biological functional groups. These groups are classified as non-polar and polar based on the atom’s composition and arrangements. Thus function groups are significant in various biological reactions. The molecules such as Proteins, lipids, DNA, and carbohydrates are formed with these groups. The most significant biological functional groups are phosphate, carbonyl, hydroxyl, methyl, carboxyl, sulfhydryl groups, and amino. These groups in the molecules can modify solubility, structure and their reactivity, and so on. Different molecules in biology may carry single or many functional groups and varying combinations of the same. These functional groups exhibit specific consistent reactions and characteristics without being dependent on the molecule they are present. The set of atoms that is present in a molecule is important for the molecule’s particular characteristics or properties.
