Which class of lipids is made up of rigid carbon rings with no fatty acid tails?
A
Steroids
B
Waxes
C
Phospholipids
D
Triglycerides
Verified step by step guidance1
Understand the structure of each lipid class mentioned in the problem: Steroids, Waxes, Phospholipids, and Triglycerides.
Recall that steroids are characterized by a structure consisting of four fused carbon rings, making them rigid and distinct from other lipid classes.
Note that waxes are composed of long-chain fatty acids esterified to long-chain alcohols, which include fatty acid tails.
Phospholipids consist of a glycerol backbone, two fatty acid tails, and a phosphate group, making them structurally different from steroids.
Triglycerides are composed of a glycerol backbone bonded to three fatty acid tails, which also differentiates them from steroids.
