WebHere, the concentrations of amino acids from two particles from different touchdown sites (TD1 and TD2) are reported. The concentrations show that N,N-dimethylglycine (DMG) is the most abundant amino acid in the TD1 particle, but below detection limit in the other. The TD1 particle mineral components indicate it experienced more aqueous alteration. Most amino acids are synthesized from α-ketoacids, and later transaminated from another amino acid, usually glutamate. The enzyme involved in this reaction is an aminotransferase. α-ketoacid + glutamate ⇄ amino acid + α-ketoglutarate Glutamate itself is formed by amination of α-ketoglutarate: α-ketoglutarate + NH 4 ⇄ glutamate songs about pain
