The Hydrolyzation of Collagen by Fucoidan Olisosaccharide's Complex with Ce~(IV)

Fucoidan is such a polysaccharide that its hydroxies are easy to combine with lanthanons ion (CeIV) to form complex. This work obtained the complexes of three fucoidan oligosaccharides with different molecular weights F1(>5000), F2 (1000-5000) and F3(<1000) by hydrolyzing Oligosaccharide collagen with sulfuric acid. It is found that the fucoidan oligosaccharide F3 can form complex with more CeIV than F1 and F2. Hydrolyzing collagen with the complex was carried out to produce amino acid and peptides. All the three fucoidan oligosaccharide complexes with CeIV( F1, F2, F3) can catalyze by the artificial hydrolytic enzyme, and the activity of the complex of F3 is the highest.     

Proline with or without Hydroxyproline Influences Collagen Concentration and Regulates Prolyl 4-Hydroxylase α(I) Gene Expression in Juvenile Turbot(Scophthalmus maximus L.)

This study was conducted to investigate the effect of dietary proline(Pro), and Pro and hydroxyproline(Hyp) in combination on the growth performance, total Hyp and collagen concentrations of tissues, and prolyl 4-hydroxylase α(I)(P4H α(I)) gene expression in juvenile turbot feeding high plant protein diets. A diet containing 50% crude protein and 12% crude lipid was formulated as the basal and control, on which other two protein and lipid contents identical experimental diets were formulated by supplementing the basal with either 0.75% Pro(Pro-0.75) or 0.75% Pro and 0.75% Hyp(Pro+Hyp). Four groups of fish in indoor seawater recirculating systems, 35 individuals each, were fed twice a day to apparent satiation for 10 weeks. The results showed that dietary Pro and Hyp supplementation had no significant effect on growth performance and feed utilization of juvenile turbot(P 0.05). Total Hyp and collagen concentrations in muscle were significantly increased when dietary Pro and Hyp increased(P 0.05), and fish fed diet Pro+Hyp showed significantly higher free Hyp content in plasma than those fed other diets(P 0.05). The expression of P4 H α(I) gene in liver and muscle was significantly up regulated in fish fed diet Pro-0.75 in comparison with control(P 0.05); however the gene was significantly down regulated in fish fed diet Pro+Hyp in muscle in comparison with fish fed diet Pro-0.75(P 0.05). It can be concluded that supplement of crystal L-Pro and L-Hyp to high plant protein diets did not show positive effects on growth performance of juvenile turbot, but enhanced total collagen concentrations in muscle.

The Hydrolyzation of Collagen by Fucoidan Oligosaccharide＇s Complex with CeⅣ

Fucoidan is such a polysaccharide that its hydroxies are easy to combine with lanthanons ion （Ce^IV） to form complex. This work obtained the complexes of three fucoidan oligosaccharides with different molecular weights F1 （〉5 000）, F2 （1 000-5 000） and F3 （〈 1 000） by hydrolyzing Oligosaccharide collagen with sulfuric acid. It is found that the fucoidan oligosaccharide F3 can form complex with more Ce^IV than F1 and F2. Hydrolyzing collagen with the complex was carried out to produce amino acid and peptides. All the three fucoidan oligosaccharide complexes with CeIV（ F1, F2, F3） can catalyze by the artificial hydrolytic enzyme, and the activity of the complex of F3 is the highest.

游乐中的体育 在桂西北一带的彝族,每到彝年或火把节等节庆,彝家村寨总要举行一种叫做"磋逻磋"(打磨秋)的娱乐活动. 彝族打磨秋,已有悠久的历史.在彝族民间流传着一个这样的故事:很久以前,彝家村寨一连几个月乌云遮天,不见太阳,也不下雨,草木干枯,河水断流,瘟疫流行.正在大家一筹莫展的时候,李家兄弟想出了个办法,拿来两根木头做成磨秋,兄弟俩坐在磨秋上向老天说情,求老天爷开恩.
