The molecular weight of broad bean vicilin and legumin measured by gel filtration chromatography were 135000 and 351000, DSC showed that their denature temperatures were 72℃ and 87℃ respectively. The legumin had a lowest solubility at pH 4. 5-5. 0 whereas the vicilin at pH5. 5. Vicilin and legumin were all possessed low levels of α-helical and high β-sheet secondary structure fractions. The total content of α-helical,β-sheet and β-turn fraction of vicilin and legumin reached to 90% and 78% separately showed that they had a high ordered structure in solution.

对两种组分的凝胶层析表明7S和11S的相对分子质量分别为135000和351000；DSC分析显示其热变性温度分别为72℃和87℃；溶解度分析表明：11S球蛋白在pH4.5-5.0之间，7S球蛋白在pH5.5时具有最低的溶解度；圆二色性分析结果显示7S和11S球蛋白的β-折叠结构含量分别高达40.5％和38.1％，证明二者都属于β-折叠型蛋白质，二者的α-螺旋、β-折叠和β-转角结构的含量总和分别达到了90％和78％，从而说明它们在溶液中的结构是高度有序的。

Using papain to hydrolyze the legumin and vicilin respectively showed that it could obtain higher DH from legumin than from vicilin, and the emulsifying activity of legumin hydrolysates was also increased more than vicilin hydrolysates. It was easier to hydrolyze the β-sheet fractions than α-helical fractions of broad bean legumin by papain, but to vicilin the β-sheet fractions was difficult to be hydrolyzed.

发现Papain对11S的水解程度大于7S，11S水解物的乳化活性也高于7S水解物；对水解物的圆二色性分析表明：蚕豆11S球蛋白的β-折叠结构易于被木瓜蛋白酶作用，而7S球蛋白的α-螺旋结构易于被木瓜蛋白酶作用；蛋白质分子中的α-螺旋结构对乳状液的形成和稳定起着重要作用。

To investigate the genetic differences between the Liquidambar formosana populations at different altitudes and in the same light conditions in Wuzhi Mountain of Hainan, the samples of Liquidambar formosana at 7 altitude levels and the 6 samples (among which, there were 3 samples from shade conditions and 3 from sunlight conditions) from the same altitude (700 m) were made a study in molecular biology by RAPD method, with 50 random primes in use.
