Galactan - Wikipedia
Galactan (galactosan) is a polysaccharide consisting of polymerized galactose. [1] In general, galactans in natural sources contain a core of galactose units connected by α(1→3) or α(1→6), with structures containing other monosaccharides as side-chains.

蜗牛的卵和蛋白腺的半乳聚糖，是D-半乳糖和L-半乳糖以6∶1的比例缩合成胶体状粘液，因为与糖原类似，所以亦称半乳糖原，含L-构型的糖是其特点。 半乳聚糖，英文名是galactan，是水解几乎或完全生成半乳糖的多糖的总称。
Galactan - an overview | ScienceDirect Topics
Galactans are polysaccharides that are found in primary cell walls and can be (1-4)-linked β-d-Galp. They are often attached to pectic polysaccharides and can undergo turnover during cell growth. Recent research suggests that galactans play a role in controlling the crystallization of cellulose in the cell wall.
生科院张阿英教授团队揭示细胞壁组分调控植物耐盐新机制
β-1,4-半乳聚糖由半聚糖合成酶（galactan synthase, gals）合成，有gals1, gals2和gals3三个基因负责编码gals，该研究发现，只有gals1在基因表达水平上响应盐胁迫诱导，而且进一步研究发现，gals1的表达受转录因子bpc1和bpc2直接调控。
Galactan - an overview | ScienceDirect Topics
Galactan is a natural polysaccharide composed of the galactose units. The well-known source of galactan are terrestrial plants and macroalgae especially the marine algae. The established rheological properties of galactan has increased its industrial applications. The polymer is structurally complex compared to other natural polysaccharides.

Galactan is a polysaccharide composed of galactose residues linked by β-1,4 glycosidic bonds, and arabinan consists of arabinose residues (→5)-α-L-Araf). AG-I is identified as a β -(1,4)-linked galactan chain with branches of one or more α -(1,5)-linked L-Ara f …
Galactans and Its Applications - SpringerLink
2014年1月1日 · Galactan is a generic term to design a very large family of polysaccharides identified in terrestrial plants and other organisms but above all in red marine macroalgae. They are mainly represented by agars and carrageenans which have been largely investigated and used in industry for their unique rheological properties.
Galactans: An Overview of their Most Important Sourcing and ...
2011年12月1日 · However, some galactans are more complex and their specific structural features have been characterized after their extraction from terrestrial plants, seaweeds but also animals and microoragnisms....
Structural Diversity in Galactans From Red Seaweeds and Its …
Galactans are important components of many plant cell walls. Besides, they are the major polysaccharides in extracellular matrixes from different seaweeds, and other marine organisms, which have an acidic character due to the presence of sulfate groups in their structures.
Making tuberculosis more susceptible to antibiotics
2020年9月16日 · MIT chemists have discovered that changing the length of the carbohydrate galactan can dramatically affect its function. In a study of mycobacteria, the type of bacteria that cause tuberculosis and other diseases, they found that shortening galactan impairs some cell functions and makes the cells much more susceptible to certain antibiotics.
