Definition & Meaning of "fatty acid"

What is "fatty acid"?

Fatty acids are essential components of fats, which are important for various bodily functions. They come in three main types: saturated, unsaturated, and trans fats. Saturated fats are typically solid at room temperature and found in foods like butter, cheese, and red meat. Unsaturated fats, which are usually liquid at room temperature, are found in foods like olive oil, nuts, and avocados. Trans fats are artificially created through a process called hydrogenation and are found in some processed foods. Fatty acids play critical roles in energy storage, insulation, and cell structure. Some, like omega-3 and omega-6, are essential fatty acids that the body cannot produce and must be obtained through diet, contributing to brain function, inflammation regulation, and heart health.
