65. The biochemical feature that determines the density of a lipoprotein particle during ultracentrifugation analysis is the

A. Total number of nitrogenous bases in its core
B. Ratio of dense proteins to low-density lipid components
✓
C. Overall length of its attached carbohydrate chains
D. Concentration of dissolved iron atoms inside its matrix

📝 Explanation

Proteins are denser than lipids (1.3 g/mL vs. 0.9 g/mL). Particles containing more protein and less lipid exhibit a higher overall density.

📖 Additional Information

  • Total number of nitrogenous bases in its core
