components of cells such as chromosomes, membranes and lysosomes may be damaged over a period of seconds to hours 細胞組織如染色體細胞膜和溶小體會在數(shù)秒至數(shù)小時之間被破壞。
One of the most important plant plycoproteins is extensin, a structural component of cell walls, in which the side chains are tetrasaccharides of arabinose 伸展蛋白是一種最重要的植物糖蛋白,它是一種細胞壁的組分,其側(cè)鏈是阿拉伯四聚糖。
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(磷脂酰膽堿):磷脂的一種,由甘油、脂肪酸、磷酸和膽堿組成,在高等動植物中廣泛存在,是細胞膜的重要組分。
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.筍細胞壁的利用狀況,利用石蠟切片半薄切片和超薄切片技術(shù),通過光鏡和透射電子顯微鏡觀察,對比研究野生大熊貓食物和糞便中的松花竹筍細胞壁的形態(tài)。發(fā)現(xiàn)竹筍經(jīng)過大熊貓的消化后,其細胞壁在形態(tài)上有明顯的變化,薄壁細胞細胞壁變薄,厚壁細胞初生壁和次生壁都有部分消失缺損或扭曲。
