Lipids are a heterogeneous group of organic compounds that are hydrophobic and soluble in organic solvents. They are essential components of cells, contributing to their structure and functioning.
Fatty acids are a type of organic acid that serves as a building block for lipids. They are composed of a hydrocarbon chain with a carboxyl group (-COOH) at one end. Fatty acids can be either saturated or unsaturated, depending on the presence or absence of double bonds in their hydrocarbon chain.
C15H31COOH (Palmitic Acid).
C17H35COOH (Stearic Acid).
Lipids are commonly found in animal-based foods such as meat, poultry, fish, eggs, and dairy products. Animal fats, like lard and butter, are rich sources of lipids.
Certain plant-based foods contain lipids, including oils derived from olives, sunflower seeds, soybeans, coconuts, avocados, and nuts such as almonds and walnuts.
Many processed foods, such as baked goods, snacks, and fried foods, contain added fats and oils that contribute to the lipid content.
