结构重复单元

每8个糖残基构成一个结构重复单元，其中六个为α-1,3-D-Glc，两个为α-1，3-D-Man；

Every eight sugar residues of the backbone consist a repeating unit ;

第二种方案是数字光刻技术，用图形设计软件CorelDraw在图像中设计光栅结构的重复单元来模拟传统全息制作中物光和参考光干涉形成的干涉条纹。

The second program is the use of digital lithography . Designing many repetitive units in the picture by graphic design software CorelDraw to simulate the interference fringe of which is the result of the object light and reference light interfere .

在真核细胞中，所有的基因组DNA与高度进化保守的碱性蛋白&组蛋白以及多种组蛋白相关染色质因子组装构成核小体结构，重复此单元而形成染色质结构。

In eukaryotic cells , all genomic DNA with a high degree of evolutionary conservation of basic protein & histone and histone-related chromatin assembly factors constitute a nucleosome structure ; the repetition of this element forms chromatin structure .

Cf蛋白定位于细胞质膜，但主体在膜外，主要结构域为富含亮氨酸重复（LRR）和跨膜结构域。LRR重复单元数目以及N端序列决定了Cf蛋白对Avr的识别特异性。

The Cf proteins , which are anchored at plasma membrane with the main body outside , mainly consist of a leucine-rich repeat ( LRR ) and a transmembrane domain .
