Sativa meal and both weight gain rate and relative growth rate also increased significantly. The above indexes of fish fed 4% and 12% M. sativa meal were higher than those of fish fed 16% M. sativa meal and were lower for fish fed fresh M. sativa than that of the control group. 2 With increased levels of M. sativa meal in the diets, crude protein content in the muscle of fish fed M. sativa meal increased significantly, while EE and cholesterol were significantly decreased and moisture showed a quadric curve variation. Fish fed fresh M. sativa had no improvement in comparison to the control group. 3 Protease and amylase in foregut, midgut, hindgut and hepatopancreas of C. carpio increased with increased M. sativa meal but the variation was not linear.

试验Ⅰ、Ⅲ组的上述2项指标高于对照组，试验Ⅳ组低于对照组，苜蓿鲜草组低于对照组，但差异均不显著。2和对照组相比，添加苜蓿草粉显著或极显著提高了禾花鲤肌肉中粗蛋白质含量，随着苜蓿草粉添加水平的增加，肌肉中粗脂肪和胆固醇水平显著下降，肌肉中水分含量呈先降后升的二次变化趋势，苜蓿鲜草组的肌肉中粗蛋白质、粗脂肪含量和胆固醇水平无显著变化。3添加苜蓿草粉后对消化道各部位蛋白酶活性及淀粉酶活性有促进作用，均呈先升后降的变化趋势，其中试验Ⅱ组的酶活性最高。

The protease activity in foregut was higher than that of midgut in an acidic condition at pH 5.0-5.8, while in an alkalescence condition at pH 7.0-8.6, the protease activity was higher in midgut than that in foregut. The lipase activity of foregut was high and stable in two pH ranges: 4.2-5.0 and 6.2-7.0, and that of midgut was high at pH 3.8, while the lipase lost enzyme activity at pH over 9.0. The amylase activity was high and stable at pH 6.6-7.4 in both foregut and midgut. The cellulase activity of foregut and midgut was high and stable at pH 6.2-7.4 and 5.4-7.0 respectively.

刺参前肠蛋白酶活力在酸性环境下较中肠高，且在反应pH为5.0-5.8之间酶活力相对稳定，而中肠蛋白酶活力在碱性环境下较前肠高，且在反应pH为7.0-8.6之间酶活力相对稳定；刺参前肠脂肪酶活力随着pH的升高出现两个相对稳定的峰值，分别为4.2-5.0和6.2-7.0区间，中肠脂肪酶活力在pH为3.8时达到最大值，而在pH超过9.0明显失活；刺参前肠和中肠淀粉酶活力在pH变化时表现出相似的变化趋势，在反应pH为6.6-7.4之间酶活力较高且相对稳定；刺参前肠和中肠中纤维素酶活力在pH变化时反应不一致，前肠淀粉酶在反应pH为6.2-7.4之间酶活力较高且相对稳定，中肠纤维素酶活力在反应pH为5.4-7.0之间酶活力较高且相对稳定。

The relative activity of a lipase from Candida valida Z6 was studied in hydrolysis of simple esters,fatty acid glycerides and lipidse.

通过与一种不同来源的脂肪酶作比较，研究了粗状假丝酵母诱变株Z6产脂肪酶水解不同底物的相对酶活，包括对低级酯、脂肪酸甘油酯和天然油脂的水解。

Samples of tissue displayed the molecular signature of brown fat, including a key heat-producing protein that was absent from white fat.

这些组织的采样显示出棕色脂肪的分子特征，包括一种产生热量的关键蛋白质，这种蛋白质并不存在于白色脂肪中。

FOXC2 affects adipocyte metabolism by increasing the sensitivity of the β-adrenergic-cAMP-protein kinase A signaling pathway through alteration of adipocyte PKA holoenzyme composition.

FOXC2通过对各种参与代谢重要基因的调控和提高β-肾上腺素能－cAMP-蛋白激酶A信号通路的敏感性，改变脂肪细胞PKA全酶的组成来影响脂肪细胞的代谢。

Results In 3T3-L1 adipocytes, isoproterenol at the concentration of 10 μmol/L reduced the adiponectin secretion and insulin at the concentration of 5 nmol/L could block the inhibitory effect of isoproterenol. In 313-Li adipocytes expressed myrAkt, adiponectin secretion decreased significantly, isoproerenol treatment increased adiponectin and insulin couldn't block the effect of isoproterenol.

结果 异丙肾上腺素可明显降低3T3-L1脂肪细胞脂联素的蛋白质表达，胰岛素可纠正这一变化；表达myrAkt的3T3-L1脂肪细胞中脂联素明显减少，异丙肾上腺素可增加脂联素蛋白的表达，胰岛素不能纠正这一变化。

The next leanest is ground round (for 218 calories, 13 grams of fat), then ground chuck and ground beef (both about 231 calories, 15 grams of fat).

还有一种能够瘦身的牛精肉，它含有218卡路里，13克脂肪，然后是牛颈肉和绞细牛肉，它们都含有231卡路里，15克脂肪。
