【摘要】 用ＳＤＳＰＡＧＥ法研究了酸溶胶原中的α１，α２，β１１，β１２组份在中性水溶液以及加入盐（ＡｕＣｌ３等）后的水解能力．实验表明：在水溶液中，α１与α２的水解能力相近，β１１与β１２的水解能力也相差不多．但在加入与乳剂成熟条件一致的金属盐［ＡｕＣｌ３（０．１６７‰，ＮＨ４ＣＮＳ（２‰）和Ｎａ２Ｓ２０３（１‰）］之后，由于金属离子（尤其是Ａｕ３＋）的影响，α１的水解能力明显大于α２，β１１的水解能力明显大于β１２．本文还讨论了影响胶原中不同组份水解能力的各种因素．更多还原

【Abstract】  systematic research was made to observe and compare the hydrolysis capacity of different individual conformational components (α1, α2, β11, β12)seperated from acidsoluble collagen. The experimental data clearly showed that under the liquid solution(pH=7.0), after hydrolysis for 4.5 h, α1, α2, β11, β12 had all greatly hydrolyzed, and the hydrolysis capacity of α1 matched that of α2, the hydrolysis capacity of β11 was as great as that of β12; but under the salt solution, the hydrolysis capacity of α1 was greater than that of α2, the hydrolysis capacity of β11 was greater than that of β12. The difference of hydrolysis capacity between α1 and α2, under salt condition was likely due to the content difference of Glu & Asp which could complex with Au3+ in the α components. The main results and conclusions might be of reference value in deeply exploiting the research of collagen reactivity and in practically solving the problem how to maintain and improve the physicomechanical properties of gelatin emulsion layer or a gelatin coating layer in general. 更多还原
