==Amino acids identified== {{Category see also|Chemical synthesis of amino acids}} Below is a table of amino acids produced and identified in the "classic" 1952 experiment, as analyzed by Miller in 1952<ref name="miller19532" /> and more recently by Bada and collaborators with modern mass spectrometry,<ref name="bada20132" /> the 2008 re-analysis of vials from the volcanic spark discharge experiment,<ref name="bada20132" /><ref name="Johnson-2008" /> and the 2010 re-analysis of vials from the H<sub>2</sub>S-rich spark discharge experiment.<ref name="bada20132" /><ref name="Parker-2011" /> While not all proteinogenic amino acids have been produced in spark discharge experiments, it is generally accepted that early life used a simpler set of prebiotically-available amino acids.<ref name="Singh M.-2002" /> {|class="wikitable sortable" style="text-align:right" |- ! scope="col" rowspan="2" | Amino acid ! colspan="4" scope="col" | Produced in experiment ! scope="col" rowspan="2" | [[Proteinogenic]] |- ! scope="col" | Miller–Urey<br />{{small|(1952)}} ! scope="col" | Bada Reanalysis of 1950s product<br />{{small|(2008–)}} ! scope="col" | Volcanic spark discharge<br />{{small|(2008)}} ! scope="col" | H<sub>2</sub>S-rich spark discharge<br />{{small|(2010)}} |- |[[Glycine]] | {{ya}} | {{ya}} | {{ya}} | {{ya}} | {{yes}} |- |[[alanine|α-Alanine]] | {{ya}} | {{ya}} | {{ya}} | {{ya}} | {{yes}} |- |[[beta-Alanine|β-Alanine]] | {{ya}} | {{ya}} | {{ya}} | {{ya}} | {{no}} |- |[[Aspartic acid]] | {{ya}} | {{ya}} | {{ya}} | {{ya}} | {{yes}} |- |[[alpha-Aminobutyric acid|α-Aminobutyric acid]] | {{ya}} | {{ya}} | {{ya}} | {{ya}} | {{no}} |- |[[Serine]] | {{na}} | {{ya}} | {{ya}} | {{ya}} | {{yes}} |- |[[Isoserine]] | {{na}} | {{na}} | {{ya}} | {{ya}} | {{no}} |- |[[2-Aminoisobutyric acid|α-Aminoisobutyric acid]] | {{na}} | {{ya}} | {{ya}} | {{ya}} | {{no}} |- |[[3-Aminoisobutyric acid|β-Aminoisobutyric acid]] | {{na}} | {{ya}} | {{ya}} | {{ya}} | {{no}} |- |[[beta-Aminobutyric acid|β-Aminobutyric acid]] | {{na}} | {{ya}} | {{ya}} | {{ya}} | {{no}} |- |[[gamma-Aminobutyric acid|γ-Aminobutyric acid]] | {{na}} | {{ya}} | {{ya}} | {{ya}} | {{no}} |- |[[Valine]] | {{na}} | {{ya}} | {{ya}} | {{ya}} | {{yes}} |- |[[Isovaline]] | {{na}} | {{ya}} | {{ya}} | {{ya}} | {{no}} |- |[[Glutamic acid]] | {{na}} | {{ya}} | {{ya}} | {{ya}} | {{yes}} |- |[[Norvaline]] | {{na}} | {{ya}} | {{ya}} | {{na}} | {{no}} |- |[[Methylamine]] | {{na}} | {{ya}} | {{ya}} | {{ya}} | {{no}} |- |[[Ethylamine]] | {{na}} | {{ya}} | {{ya}} | {{ya}} | {{no}} |- |[[Ethanolamine]] | {{na}} | {{ya}} | {{ya}} | {{ya}} | {{no}} |- |[[Isopropylamine]] | {{na}} | {{ya}} | {{ya}} | {{na}} | {{no}} |- |[[n-Propylamine]] | {{na}} | {{ya}} | {{ya}} | {{na}} | {{no}} |- |[[alpha-Aminoadipic acid|α-Aminoadipic acid]] | {{na}} | {{na}} | {{ya}} | {{na}} | {{no}} |- |[[Homoserine]] | {{na}} | {{na}} | {{ya}} | {{na}} | {{no}} |- |[[2-Methylserine]] | {{na}} | {{na}} | {{ya}} | {{na}} | {{no}} |- |[[3-Hydroxyaspartic acid|β-Hydroxyaspartic acid]] | {{na}} | {{na}} | {{ya}} | {{na}} | {{no}} |- |[[Ornithine]] | {{na}} | {{na}} | {{ya}} | {{na}} | {{no}} |- |[[2-Methylglutamic acid]] | {{na}} | {{na}} | {{ya}} | {{na}} | {{no}} |- |[[Phenylalanine]] | {{na}} | {{na}} | {{ya}} | {{na}} | {{yes}} |- |[[Homocysteic acid]] | {{na}} | {{na}} | {{na}} | {{ya}} | {{no}} |- |[[S-methylcysteine|''S''-Methylcysteine]] | {{na}} | {{na}} | {{na}} | {{ya}} | {{no}} |- |[[Methionine]] | {{na}} | {{na}} | {{na}} | {{ya}} | {{yes}} |- |[[Methionine sulfoxide]] | {{na}} | {{na}} | {{na}} | {{ya}} | {{no}} |- |[[Methionine sulfone]] | {{na}} | {{na}} | {{na}} | {{ya}} | {{no}} |- |[[Isoleucine]] | {{na}} | {{na}} | {{na}} | {{ya}} | {{yes}} |- |[[Leucine]] | {{na}} | {{na}} | {{na}} | {{ya}} | {{yes}} |- |[[Ethionine]] | {{na}} | {{na}} | {{na}} | {{ya}} | {{no}} |- |[[Cysteine]] | {{na}} | {{na}} | {{na}} | {{na}} | {{yes}} |- |[[Histidine]] | {{na}} | {{na}} | {{na}} | {{na}} | {{yes}} |- |[[Lysine]] | {{na}} | {{na}} | {{na}} | {{na}} | {{yes}} |- |[[Asparagine]] | {{na}} | {{na}} | {{na}} | {{na}} | {{yes}} |- |[[Pyrrolysine]] | {{na}} | {{na}} | {{na}} | {{na}} | {{yes}} |- |[[Proline]] | {{na}} | {{na}} | {{na}} | {{na}} | {{yes}} |- |[[Glutamine]] | {{na}} | {{na}} | {{na}} | {{na}} | {{yes}} |- |[[Arginine]] | {{na}} | {{na}} | {{na}} | {{na}} | {{yes}} |- |[[Threonine]] | {{na}} | {{na}} | {{na}} | {{na}} | {{yes}} |- |[[Selenocysteine]] | {{na}} | {{na}} | {{na}} | {{na}} | {{yes}} |- |[[Tryptophan]] | {{na}} | {{na}} | {{na}} | {{na}} | {{yes}} |- |[[Tyrosine]] | {{na}} | {{na}} | {{na}} | {{na}} | {{yes}} |}
