Q: What was the first amino acid to be isolated?


Read this paragraph and choose the correct option from the provided answers:

The first amino acid to be isolated was asparagine in 1806. It was obtained from protein found in asparagus juice (hence the name). Glycine, the major amino acid found in gelatin, was named for its sweet taste (Greek glykys, meaning “sweet”). In some cases an amino acid found in a protein is actually a derivative of one of the common 20 amino acids (one such derivative is hydroxyproline). The modification occurs after the amino acid has been assembled into a protein.

 Choices:

- histamine

- histon

- glutathione

- asparagine


A:
asparagine
