Fumaric acid overview
Structure and Properties
Fumaric acid is a dicarboxylic acid with the molecular formula C₄H₄O₄. It contains two carboxylic acid groups located on opposite sides of a double bond, chemically known as the trans configuration. This configuration makes fumaric acid more stable than maleic acid. In maleic acid, the two carboxylic acid groups are located on the same side of the double bond. Fumaric acid is more stable due to its smaller interatomic distance.
The table below lists the differences between fumaric acid and maleic acid:
| Property | Fumaric Acid (trans) | Maleic Acid (cis) |
|---|---|---|
| Molecular Formula | C₄H₄O₄ | C₄H₄O₄ |
| Configuration | Trans (E) | Cis |
| Carboxylic Groups Orientation | Opposite sides of double bond | Same side of double bond |
| Stability | More stable | Less stable |
| Melting Point | 287°C | 139°C |
| pKa₁ | 3.03 | Lower than fumaric acid |
| pKa₂ | 4.44 | Lower than fumaric acid |
Fumaric acid has a high melting point, ranging from 286 to 302°C. It is readily soluble in water. At 25°C, 6.6 grams of fumaric acid dissolves in 100 milliliters of water. Its acidity constants, pKa1 and pKa2, are 3.02 and 4.44 respectively. These values indicate that it is a weak acid.
Industrial and Biological Applications
NORBIDAR is a leading producer of fumaric acid, providing high-quality products to numerous industries. In the food industry, fumaric acid is used to improve the taste of foods such as beverages, confectionery, and baked goods. It also helps maintain the freshness and safety of food. In animal feed, it helps animals grow and maintain their stomach health.
Pharmaceutical companies use fumaric acid in drugs. It helps tablets dissolve and helps control the pH of liquid medications. In the personal care industry, it helps maintain the product’s condition and improves skin feel.
Fumaric acid is essential for living organisms. Cells use fumaric acid in the citric acid cycle and convert it into malic acid. This helps organisms obtain energy from food. The unique molecular structure of fumaric acid enables it to play a role in nature and industrial production. The conjugate of fumaric acid is called fumarate. Fumarate also participates in these important reactions.
Formation of Fumarate Conjugates
Chemical Reaction
Chemists call the reaction in which fumaric acid loses a proton a deprotonation reaction. Fumaric acid contains two carboxyl groups, each of which can release a hydrogen ion. When a hydrogen ion leaves, the molecule transforms into a fumaric acid conjugate.
The newly formed molecule is called fumarate, with the molecular formula C₄H₃O₄⁻. This formula represents the removal of a hydrogen atom from the molecule. The negative charge is located on the oxygen atom in the carboxyl group. Scientists point out that fumarate molecules do not contain hydrogen bonds, and their structure remains open and stable.
Note: Fumarate conjugates readily form in water. This process helps control the acidity of many products.
Stepwise Deprotonation
Fumaric acid can lose two protons, but the first step involves the formation of a fumaric acid conjugate. This process occurs in two steps:
Step 1 Deprotonation:
The first carboxyl group loses a hydrogen ion. The molecule becomes the fumarate ion (C4H3O4-).
Step 2 Deprotonation:
The second carboxyl group also loses a hydrogen ion. The molecule becomes a divalent anion, called fumarate (2-).
Most reactions in factories and living organisms use the monovalent anionic form, fumarate (1-). This form is crucial in the citric acid cycle and product manufacturing. The fumarate ion is more reactive and has a wider range of applications because it lacks intramolecular hydrogen bonds.
Scientists and companies like NORBIDAR use fumaric acid conjugates because of their stability and effectiveness. Stepwise deprotonation helps control the acidity and reactivity of food, animal feed, pharmaceuticals, and personal care products.
Structure and Name of Conjugates
Structural Formula
The conjugate of fumaric acid has a simple structure. Chemists have identified it as consisting of four carbon atoms, three hydrogen atoms, and four oxygen atoms, with the molecular formula C₄H₃O₄⁻. One oxygen atom carries a negative charge due to the removal of a hydrogen ion from it. The molecule maintains a trans configuration, meaning that two carboxyl groups are located on opposite sides of the molecule.
Chemists use this structure to study the mechanisms of action of the fumaric acid conjugate in water and organisms.
IUPAC Nomenclature and Common Names
Scientists use several names for the fumaric acid conjugate. Its official IUPAC name is “E-butenedioic acid.” The letter “E” indicates that the molecule is in a trans configuration. Most people refer to it as “fumaric acid.” This name appears in books, research reports, and industry papers.
| Name Type | Name |
|---|---|
| IUPAC Name | E-butenedioate |
| Common Name | Fumarate |
| Systematic Name | (E)-2-butenedioate |
Fumaric acid conjugates play a crucial role in the citric acid cycle. They also help control acidity in food and animal feed. NORBIDAR uses fumarate extensively due to its stability and ease of use.
Importance and Properties of Fumaric Acid
Chemical Stability
Fumaric acid and its conjugate base, fumarate (1-), are very stable. This stability is critical for their application in plants. Fuumarate (1-) remains safe under proper storage conditions. However, bacteria can break it down if exposed to air or water. If fumarate (1-) is heated with water, it converts to DL-malic acid. This occurs at high temperatures. To maintain its effectiveness, the company stores it in tightly closed containers in a cool, dry place.
| Stability Aspect | Details |
|---|---|
| Degradation | Susceptible to degradation by aerobic and anaerobic microorganisms |
| Reaction | Forms DL-malic acid when heated with water at 150–170°C |
| Storage | Should be stored in a well-closed container in a cool, dry place |
These stability properties help workers handle fumaric acid safely. Proper storage conditions ensure that fumaric acid, once bound to proteins, is readily available for use in a variety of products.
