Question

part a which of the following formulas represents an amino acid? \\(\ce{c3h7no2}\\), \\(\ce{c6h12o6}\\), \\(\ce{c10h16n5o13p3}\\), \\(\ce{c55h98o6}\\)

Explanation:

Amino acids have the general formula \( C_xH_yO_2N \) (or with additional groups, but must have at least one amino (\( -NH_2 \)) and one carboxyl (\( -COOH \)) group, so the formula should have C, H, O, N with O around 2 and N around 1. Let's analyze each option:

• \( C_3H_7NO_2 \): Contains C, H, O, N with O=2, N=1, matching amino acid general formula.
• \( C_6H_{12}O_6 \): No N, it's a carbohydrate (glucose-like).
• \( C_{10}H_{16}N_5O_{13}P_3 \): Has P, likely a nucleotide (like ATP/DNA component).
• \( C_{55}H_{98}O_6 \): No N, likely a lipid (fatty acid/triglyceride).

So \( C_3H_7NO_2 \) fits the amino acid structure.

Answer:

\( \boldsymbol{C_3H_7NO_2} \) (the first option, though labeled with the formula \( C_3H_7NO_2 \))
