The origin of the ethylene carbon skeleton in Penicillium digitatum appears to be intimately associated with the Krebs cycle acids, particularly the middle carbon atoms of dicarboxylic acids. Among the other compounds studied, certain carbon atoms of beta-alanine, propionic acid, and methionine can be incorporated into the ethylene carbon skeleton presumably by way of an indirect route via the Krebs cycle acids. Carbon atoms of acrylic acid, particularly C-2, were also found to be incorporated into the ethylene skeleton. Inhibition of ethylene but not respiratory CO(2) formation in the mold by cis-3-chloroacrylic acid at 1 x 10(-3)m pointed to the possibility that acrylic acid may be related to the precursor for ethylene.
指状青霉中乙烯碳骨架的起源似乎与三羧酸循环酸密切相关,尤其是二羧酸的中间碳原子。在研究的其他化合物中,β-丙氨酸、丙酸和蛋氨酸的某些碳原子可能通过三羧酸循环酸的间接途径被整合到乙烯碳骨架中。丙烯酸的碳原子,特别是C-2,也被发现整合到乙烯骨架中。1×10⁻³m的顺式-3-氯丙烯酸对霉菌中乙烯而非呼吸性CO₂形成的抑制作用表明,丙烯酸可能与乙烯的前体有关。
