What Are Fatty Acids?
Fatty acids are carboxylic acids with long hydrocarbon chains. They are classified based on their chemical structure into three main types: saturated, unsaturated, and trans fatty acids. Each type has distinct properties that make them suitable for different industrial applications.
Major Types of Fatty Acids
Saturated Fatty Acids
Saturated fatty acids are typically solid at room temperature and are found in animal fats such as butter and lard, as well as in specific plant oils like coconut and palm oil. They are chemically stable and resistant to oxidation, making them valuable in applications where stability is crucial. An example of a saturated fatty acid is palmitic acid, commonly derived from meat and palm oil.
Unsaturated Fatty Acids
Unsaturated fatty acids remain liquid at room temperature and are classified into two subtypes:
- Monounsaturated Fatty Acids (MUFAs): MUFAs have one double bond in their structure. Oleic acid, found in olive oil, is a prominent example. Other sources include avocados, nuts, and various plant oils such as canola and sesame oil.
- Polyunsaturated Fatty Acids (PUFAs): PUFAs have multiple double bonds. They are found in fish oils, flaxseeds, and walnuts. Key examples include linoleic acid, alpha-linolenic acid, eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA).
Trans Fatty Acids
Trans fatty acids can be both naturally occurring and artificially created. Natural trans fats are found in meat and dairy products, while artificial trans fats are produced through industrial processes like hydrogenation, resulting in products such as margarine and processed foods. These are often solid at room temperature and are used to enhance texture and extend shelf life.
