Question

amino acid monosaccharide complete the table to compare these structures. amino acid monosaccharide is a building block of proteins contains oxygen has a carboxyl group

Explanation:

Step1: Analyze "Is a building block of proteins"

Proteins are made up of amino acids. Monosaccharides are building blocks of carbohydrates (like polysaccharides). So amino acid is a building block of proteins (✔), monosaccharide is not (✖).

Step2: Analyze "Contains oxygen"

Looking at the structures:

• Amino acid: has oxygen in the carbonyl (\(C = O\)) and hydroxyl (\(-OH\)) groups.
• Monosaccharide: has multiple hydroxyl (\(-OH\)) groups. So both contain oxygen (✔ for both).

Step3: Analyze "Has a carboxyl group"

A carboxyl group is \(-COOH\). The amino acid structure shown has \(-COOH\) (✔). The monosaccharide structure does not have a \(-COOH\) group (✖).

Answer:

• Is a building block of proteins: Amino acid (✔), Monosaccharide (✖)
• Contains oxygen: Amino acid (✔), Monosaccharide (✔)
• Has a carboxyl group: Amino acid (✔), Monosaccharide (✖)
