Biochemical Statement Accuracy Steps:

• Examine each statement against standard biological definitions for macromolecules and bonds.
• Verify ratios, compositions, and processes using known formulas like Cn(H2O)n for carbohydrates.
• Check membrane components and lipid structures from cell biology principles.
• Confirm bond formation reactions, such as condensation in polymers.

Why B is correct:

• Triglycerides form lipid bilayers and are integral to all eukaryotic cell surface membranes as energy storage and structural elements.

Why the others are wrong:

• A: Carbohydrates have a 1:2:1 C:H:O ratio, not 2:1 for C:O.
• C: Phospholipids typically have one saturated and one unsaturated chain for fluidity.
• D: Glycosidic bonds form via condensation, releasing water, but the statement is incomplete without specifying the reaction type.

Final answer: B
