Amino Acids Guide

The first few amino acids were discovered in the early 1800s. In 1806, the French chemists Louis-Nicolas Vauquelin and Pierre Jean Robiquet isolated a compound in asparagus that proved to be asparagine, the first amino acid to be discovered.[3][4] Another amino acid that was discovered in the early 19th century was cystine, in 1810,[5] although its monomer, cysteine, was discovered much later, in 1884.[4][6]Glycine and leucine were also discovered around this time, in 1820.[7]...
