The use of a range of modern analytical techniques has facilitated the structural characterisation of the polysaccharide from the New Zealand endemic red alga, Callophyllis hombroniana. The native polysaccharide contains a number of structural units with the largest proportion consisting of 3-linked beta-D-galactopyranosyl 2-sulfate units, alternating with 4-linked 3,6-anhydro-alpha-D-galactopyranosyl 2-sulfate units, that is, theta-carrageenan (36 mol%). C. hombroniana is the first red seaweed reported to naturally contain such a large proportion of theta-carrageenan.
一系列现代分析技术的应用促进了对来自新西兰本土红藻Callophyllis hombroniana的多糖的结构表征。天然多糖包含许多结构单元,其中比例最大的是由3-连接的β-D-吡喃半乳糖基2-硫酸盐单元组成,与4-连接的3,6-脱水-α-D-吡喃半乳糖基2-硫酸盐单元交替排列,即θ-卡拉胶(36摩尔%)。Callophyllis hombroniana是首个被报道天然含有如此高比例θ-卡拉胶的红藻。
