Verified step by step guidance

Understand the basic structure of a phospholipid. Phospholipids are a class of lipids that are a major component of all cell membranes. They can form lipid bilayers because of their amphiphilic characteristic.

Identify the components of a phospholipid. A typical phospholipid molecule consists of a glycerol backbone, two fatty acid tails, and a phosphate group. This structure is crucial for its function in cell membranes.

Compare the given options with the known structure of a phospholipid. The correct structure should include a glycerol backbone, two fatty acid tails, and a phosphate group.

Evaluate each option: - Option 1: A glycerol backbone with two fatty acid tails and a phosphate group matches the known structure of a phospholipid. - Option 2: A ring structure with alternating single and double bonds does not describe a phospholipid. - Option 3: A glycerol backbone with three fatty acid tails describes a triglyceride, not a phospholipid. - Option 4: A long hydrocarbon chain with a carboxyl group describes a fatty acid, not a phospholipid.

Conclude that the correct description of a phospholipid is 'A glycerol backbone with two fatty acid tails and a phosphate group', as it matches the known structure and function of phospholipids in biological membranes.
