使用 HPLC 对 Cl 碳质球粒陨石的原始内部碎片进行氨基酸分析，Orgueil 和 Ivuna 发现，β-丙氨酸、甘氨酸和 γ-氨基正丁酸 (ABA) 是这两块陨石中最丰富的氨基酸，浓度范围约为十亿分之 600 至 2,000 份 (ppb)。其他 α-氨基酸，如丙氨酸、α-ABA、α-氨基异丁酸 (AIB) 和异缬氨酸仅存在微量（
Amino acid analyses using HPLC of pristine interior pieces of the Cl carbonaceous chondrites Orgueil and Ivuna have found that beta -alanine, glycine, and gamma -amino-n-butyric acid (ABA) are the most abundant amino acids in these two meteorites, with concentrations ranging from approximate to 600 to 2,000 parts per billion (ppb). Other alpha -amino acids such as alanine, alpha -ABA, alpha -aminoisobutyric acid (AIB), and isovaline are present only in trace amounts (
