Question

What foundational structure has four carbon rings?

Answer 1

Methane has a tetrahedral geometry, with each of the four hydrogen atoms spaced 109.5° apart. As the backbone of the large molecules of living things, hydrocarbons may exist as linear carbon chains, carbon rings, or combinations of both.

Answer 2

Phospholipids comprise the membrane's matrix. They have a glycerol or sphingosine backbone to which two fatty acid chains and a phosphate-containing group are attached. Steroids are another class of lipids. Their basic structure has four fused carbon rings.
