Abstract
The vitreous contains collagen and soluble non-collagen proteins. The degeneration of collagen takes place in a different manner than in the other proteins. It has been detected that the cattle vitreous does not show any collagenolytic activity against the basic types of collagen (I, II, IX, and XI). The vitreous digests haemoglobin only in the acidic section of pH (optimum 3.5-4.5). No proteolytic activity towards Hb in physiological pH has been found.
摘要
玻璃体包含胶原蛋白和可溶性非胶原蛋白。胶原蛋白的降解方式与其他蛋白质不同。据检测，牛玻璃体对基本类型的胶原蛋白（I、II、IX和XI）没有任何胶原olytic活性。玻璃体仅在pH值的酸性区域（最佳pH值为3.5 - 4.5）消化血红蛋白。在生理pH值下未发现对血红蛋白的蛋白水解活性。
