components of cells such as chromosomes, membranes and lysosomes may be damaged over a period of seconds to hours 细胞组织如染色体细胞膜和溶小体会在数秒至数小时之间被破坏。
one of the most important plant plycoproteins is extensin, a structural component of cell walls, in which the side chains are tetrasaccharides of arabinose 伸展蛋白是一种最重要的植物糖蛋白,它是一种细胞壁的组分,其侧链是阿拉伯四聚糖。
lecithin ( phosphatidyl choline ) one of a group of phospholipids that contain glycerol, fatty acid, phosphoric acid, and choline that are found widely in higher plants and animals, particularly as a component of cell membranes 卵磷脂(磷脂酰胆碱):磷脂的一种,由甘油、脂肪酸、磷酸和胆碱组成,在高等动植物中广泛存在,是细胞膜的重要组分。
occurred through giant panda s alimentary canal . the cell wall became thinner, and the rupture and loss of primary and secondary wall was observed . therefore, it showed that giant panda has the ability to digest part of components of cell wall, such as pectin and semicellulose, etc . furthermore, it is possible that giant panda can digest a little cellulose . the morphological method used in this study is a new idea for nutrition research . the ability of utilization of cell wall of bamboo by giant panda is unique in carnivore . it is adaptation to its phytophage sp.笋细胞壁的利用状况,利用石蜡切片半薄切片和超薄切片技术,通过光镜和透射电子显微镜观察,对比研究野生大熊猫食物和粪便中的松花竹笋细胞壁的形态。发现竹笋经过大熊猫的消化后,其细胞壁在形态上有明显的变化,薄壁细胞细胞壁变薄,厚壁细胞初生壁和次生壁都有部分消失缺损或扭曲。
