| 摘要: |
| 合成代谢的研究结果表明, 1. 667 nmol·s-1的胰岛素对香猪、长白猪脂肪的合成均无明显的促进作用(P<0. 05), 0. 416 8 pmol·s-1的胰岛素显著促进香猪脂肪酸的生物合成(P>0. 05)。肾上腺素抑制长白猪脂肪组织14C-葡萄糖转化为脂肪酸,但促进14C-葡萄糖氧化为二氧化碳及甘油。分解代谢的研究结果表明,不同浓度的肾上腺素均促进脂肪分解,且香猪对肾上腺素的敏感性明显高于长白猪。香猪、长白猪均表现为0. 416 8 pmol·s-1的胰岛素不抑制脂解, 1. 667 nmol·s-1的胰岛素则明显抑制脂解。 |

| Abstract: |
| The efffectofhormone on lipogenisis indicated:Regardless of Xiang pig or
Landrace, pharmocological concentration of insulin didn’t stimulate adipose tissue anabolism, but physiological concentration of insulin significantly stimulated fatty acid synthesis in Xiang pig.Epinephrine inhibited 14C-glucose incorporated into fatty acid, but
stimulated glucose oxidized to CO2 and glycerol synthesis in Landrace.Any concentrations of epinephrine stimulated lipolysis.The sensitivity of epinephrine to Xiang pig was
significantly higher than Landrace. Physiological concentration of insulin didn’t inhibit
lipolysis.Pharmocological concentration of insulin significantly inhibited lipolysis. |
