Chemistry - Biomolecules Question with Solution | TestHub

Amino acids are organic compounds that contain amine $\left(-{\mathrm{NH}}_2\right)$ and carboxyl $(-\mathrm{COOH})$ functional groups, along with a side chain (R group) specific to each amino acid. a-carbon of cc-amino acid is asymmetric. Hence this statement is true. Proteins exist in both D and L -form. Human body can synthesize all proteins they need. At $\mathrm{pH}=7$, both amino and carboxylic groups exist in ionised form.
