A compound isolated from a biological source is subjected to chemical analysis. It contains carbon and oxygen in roughly equal amounts and hydrogen in an amount that is almost twice that of carbon. This compound does not take up iodine stain very well, indicating that its structure is densely packed and resistant to large molecules binding to it through noncovalent interactions. What is the likely identity of this compound?
A.
B.
C.
D.
