Question

is the structure of $\alpha $ amino acid. Based on different R groups the following amino acids are formed. Select the correct amino acid according to a different R group:

• A. $R \rightarrow H$ (alanine)
• B. $R \rightarrow CH_{3}$ (glycine)
• C. $R \rightarrow CH_{2}OH$ (serine)
• D. $R \rightarrow CH_{3}CH_{2}COOH$ (valine)

Answer 1

Answer: (C)

Amino acids are building blocks of proteins. An amino acid has an amino group and a carboxyl group attached to it. There are 22 standard amino acids. Every amino acid has side chain that has different R groups attached to it. There are 22 standard amino acids.
R ⟶ CH₂OH (serine) is the only correct pair.
