Text Solution

AI Generated Solution

The correct Answer is:
### Step-by-Step Solution: 1. **Identify the Smallest Amino Acid:** - The smallest amino acid is glycine. 2. **Understand the Common Structure of Amino Acids:** - Amino acids generally have a common structure that includes: - An amine group (-NH2) - A carboxylic acid group (-COOH) - A variable side chain (R group) which can be a hydrogen atom or a chain of carbon and hydrogen atoms. 3. **Determine the Structure of Glycine:** - For glycine, the R group is replaced by a single hydrogen atom. - Therefore, the structure of glycine can be represented as: - NH2 (amine group) - CH2 (the carbon atom to which the amine and carboxylic acid groups are attached) - COOH (carboxylic acid group) 4. **Write the Complete Structural Formula:** - The complete structural formula of glycine is: - NH2-CH2-COOH
