The oxygen isotope ratio (δ18O) of carbohydrates derived from animals, plants, sediments, and soils provides important information about biochemical and physiological processes, past environmental conditions, and geographical origins, which are otherwise not available. Nowadays, δ18O analyses are often performed on carbohydrate bulk material, while compound‐specific δ18O analyses remain challenging
氧同位素比率(δ 18 O)来自动物,植物,沉积物衍生的碳水化合物,和土壤提供了有关的生化和生理过程,过去的环境条件,以及地理来源,它们否则不提供重要的信息的。如今,δ 18个ö分析常常对碳水化合物散装材料执行,而化合物特异性δ 18个ö分析仍然具有挑战性和用于广泛的个人碳水化合物的方法是罕见的。
