Bandurski和Teas1已经证明橡胶中的橡胶起源于醋酸酯，尽管Park和Bonner2无法重复这些观察结果，也无法证明β-Hotxy-β-甲基戊二酸或β-甲基巴豆酸加入橡胶中。醋酸酯途径及其在脂肪酸和甾醇生物合成中的类似物仍然非常有吸引力。甲伐他酸已被加入橡胶2中；但巴洛和帕特里克3在应用于橡胶树冠和橡胶茎中后，无法证明它的加入。给雏鸟注射的醋酸盐大部分是针对呼吸代谢的。我们对乙酸盐和甲氧戊酸酯的掺入实验结果对Bandurski和Teas的结论的有效性提出了一些怀疑。
Bandurski and Teas1have shown that rubber inHevea brasiliensishas its origin in acetate, although Park and Bonner2have been unable to repeat these observations, and could not show the incorporation of β-hydroxy-β-methylglutarate or of β-methylcrotonate into rubber. The acetate pathway, with its analogies in fatty acid and sterol biosyntheses, remains very attractive. Mevalonate has been incorporated into rubber2; but Barlow and Patrick3were unable to show its incorporation after application toHevealeaves and stems. Much of the acetate administered toHeveaseedlings is directed towards respiratory metabolism4. The results of our experiments on incorporation of acetate and mevalonate cast some doubt on the validity of the conclusions of Bandurski and Teas.
