A phospholipid is composed of a polar, hydrophilic phosphate group 'head' and two hydrophobic (non-polar) fatty acid tails, where one tail is unsaturated (meaning it has a double bond between carbons, leading to a kinked shape).
Phospholipids are amphipathic molecules consisting of a hydrophilic (water-attracting) head group that contains a phosphate and is attached to a glycerol molecule and a hydrophobic (water-repelling) tail that contains two fatty acid chains. This structure permits different interactions based on charge and is crucial in forming biological membranes.
A phospholipid is an amphipathic molecule, or a molecule with both hydrophilic and hydrophobic components. This structure consists of a hydrophilic phosphatase-containing group (the head), and two hydrophobic fatty acid chains (the tails). The hydrophilic head group is typically made up of a phosphate group attached to a glycerol molecule. The hydrophobic tails are generally long hydrocarbon chains comprising of either saturated or unsaturated fatty acids.
This pattern allows for the dual-loving character of the phospholipid to interact differently with substances based on their charges and allows phospholipids to play a crucial role in the formation of biological membranes such as the plasma membrane.
