Three glycerol and three fatty acid molecules?

Options

A. Sucrose is a disaccharide
B. Cellulose is a polysaceharide
C. Uracil is a pyrimidine
D. Glycine is a sulphur containing amino acid

Answer

To solve the question regarding "Three glycerol and three fatty acid molecules," we need to analyze the components and their relationships. Here’s a step-by-step breakdown:

### Step 1: Understand Glycerol and Fatty Acids
- Glycerol is a simple polyol compound, which is a three-carbon molecule with hydroxyl (–OH) groups attached to each carbon.
- Fatty acids are long hydrocarbon chains with a carboxylic acid group (–COOH) at one end.

### Step 2: Identify the Combination
- When three glycerol molecules combine with three fatty acid molecules, they form a type of lipid known as triglycerides (or triacylglycerols).
- Each glycerol molecule can bind with one fatty acid molecule, resulting in the formation of three ester bonds.

### Step 3: Recognize the Structure
- The structure of triglycerides consists of a glycerol backbone with three fatty acid chains attached. This structure is crucial for energy storage in living organisms.

### Step 4: Differentiate from Other Biomolecules
- It is important to differentiate triglycerides from other biomolecules such as carbohydrates (like disaccharides and polysaccharides) and proteins (like amino acids).
- In the context of the question, we are focusing on the lipid category, specifically triglycerides.

### Step 5: Conclusion
- Therefore, the combination of three glycerol and three fatty acid molecules results in the formation of triglycerides, which are essential for energy storage in biological systems.

### Final Answer:
The combination of three glycerol and three fatty acid molecules forms triglycerides.
