Which of the following is correct statement

Options

A. proteins are not amino acids
B. `alpha`-hydrogen is present in fructose
C. starch is polymer of `alpha`-glucose
D. Amylose is compound of cellulose

Explanation

To determine which of the statements is correct, we will analyze each statement one by one.

1. **Statement 1: Proteins are not amino acids.**
- This statement is **false**. Proteins are made up of long chains of amino acids. Therefore, while proteins themselves are not amino acids, they are composed of them.

2. **Statement 2: Alpha hydrogen is present in fractals.**
- This statement is also **false**. Alpha hydrogen refers to the hydrogen atom attached to the carbon atom adjacent to a functional group (usually in organic compounds). Fractals are mathematical constructs and do not contain atoms or hydrogen.

3. **Statement 3: Starch is a polymer of alpha glucose.**
- This statement is **true**. Starch is indeed a polysaccharide that is composed of numerous units of alpha glucose linked together. This is a correct statement.

4. **Statement 4: Amylose is a compound of cellulose.**
- This statement is **false**. Amylose and cellulose are both polysaccharides made of glucose, but amylose is not a compound of cellulose. They are distinct types of polymers; amylose is a linear polymer of alpha glucose, while cellulose is a linear polymer of beta glucose.

Based on the analysis above, the only correct statement is:

**Correct Statement: Starch is a polymer of alpha glucose.**
