Hualtaco gum, from the South American plant , yields D-galactose, D-glucuronic acid, L-rhamnose and small quantities of arabinose and aldobiuronic acid on hydrolysis with strong acid. Like gum arabic, hualtaco yields a highly immunologically reactive product after mild degradation, while stronger hydrolysis furnishes an aldobiuronic acid, 6--(β-D-glucuronopyranosyl)-D-galactose, identical with that isolated similarly from gum arabic. Quantitative data are given on some of the precipitin reactions of the gum in antipneumococcal sera and the chemical basis for the reactivity in each system is discussed insofar as present knowledge permits.
源自南美植物的瓦尔塔科胶，在用强酸水解时会产生D - 半乳糖、D - 葡萄糖醛酸、L - 鼠李糖以及少量阿拉伯糖和醛二糖酸。与阿拉伯胶一样，瓦尔塔科胶在轻度降解后会产生一种具有高度免疫反应性的产物，而更强的水解则会产生一种醛二糖酸，即6 - (β - D - 吡喃葡萄糖醛酸基)-D - 半乳糖，与从阿拉伯胶中类似分离得到的产物相同。给出了该胶在抗肺炎球菌血清中的一些沉淀素反应的定量数据，并就现有知识所允许的范围讨论了每个系统中反应性的化学基础。
