Which one of the following statements is wrong

Options

A. Sucrose is a disaccharide
B. Cellulose is a polysaccharide
C. Uracil is a pyrimidine
D. Glycine is a sulfur-containing amino acid

Explanation

To determine which statement is wrong among the given options, we will analyze each statement one by one.

### Step 1: Analyze the first statement about sucrose.
- **Statement**: Sucrose is a disaccharide.
- **Explanation**: Sucrose is indeed a disaccharide composed of glucose and fructose. It is classified as a carbohydrate. Therefore, this statement is **true**.

### Step 2: Analyze the second statement about cellulose.
- **Statement**: Cellulose is a polysaccharide.
- **Explanation**: Cellulose is a complex carbohydrate and is indeed a polysaccharide made up of long chains of glucose units. It is a major component of plant cell walls. Thus, this statement is also **true**.

### Step 3: Analyze the third statement about uracil.
- **Statement**: Uracil is a pyrimidine.
- **Explanation**: Uracil is one of the nitrogenous bases found in RNA and is classified as a pyrimidine. Therefore, this statement is **true**.

### Step 4: Analyze the fourth statement about glycine.
- **Statement**: Glycine is a sulfur-containing amino acid.
- **Explanation**: Glycine is the simplest amino acid, consisting of just a hydrogen atom as its side chain (R group). It does not contain sulfur. The amino acids that contain sulfur are methionine and cysteine. Therefore, this statement is **false**.

### Conclusion:
The wrong statement is: **Glycine is a sulfur-containing amino acid.**
