details.
Here is what I used for hepatocyte.
Preparation of the fatty acid stocks
The free fatty acids are prepared by dissolving each individual free fatty
acid in 100% ethanol. Most are readily dissolved in ethanol, though some
require heating to achieve fully solubility.
A final concentration of 100 mM for each of the fatty acids as follows:
31 ul 1 M Palmitic Acid Solid, 1 g / 3.3 ml EtOH

发帖数: 351 | 4 这几种脂肪酸中，Palmitic Acid 和 Stearic Acid常温下是固体，计算摩尔浓度比较
容易。其他几种常温下是液体，但是大体上他们的密度和水的密度很相近，1ml近似1g
。这些脂肪酸都极易溶于乙醇。溶解Palmitic Acid需要略微加热（50C)。
The free fatty acids are toxic unless they are presented bound to purified,
fatty acid free, endotoxin-free serum albumin, which is used at a typical
concentration of 0.1–0.2%.
Take 31ul 1M palmitic acid, 2.8ul 1M Palmitoleic acid etc and bring the
final volume to 1000ul with 100% EtOH, you will get 0.1M FFA. Add 76ul of

1. 保护孩子首先。
2. 从你描述的症状来看。应该是不能代谢长链脂肪酸, 没法beta-oxidation
LCHAD=Long-chain 3-hydroxyacyl-coenzyme A dehydrogenase deficiency
VLCAD=Very long-chain acyl-coenzyme A dehydrogenase deficiency
最后导致长链脂肪酸堆积，导致肝损伤，直至肝硬化。
3.避免长链脂肪酸。这类的疾病用Carnitine or MCT (medium chain triglycerides)
oil supplement.跳过长链脂肪酸代谢那一步(请尊医嘱)
4.我想应该是long chain FA氧化通路上的基因的mutation导致的。
Arnold W. Strauss, MD

Deadly Diabetes Deception
Introduction
If you are an American diabetic, your physician will never tell you that
most cases of diabetes are curable. In fact, if you even mention the "cure"
word around him, he will likely become upset and irrational. His medical
school training only allows him to respond to the word "treatment". For him,
the "cure" word does not exist. Diabetes, in its modern epidemic form, is a
curable disease and has been for at least 40 years. In 2001, the most

I have a cat with kidney disease and I have heard that reducing phosphorus
intake is important for cats with kidney problems. Is it safe to feed a cat
with chronic kidney disease a raw meat diet? Doesn't it have too much
phosphorus? My cat hates the prescription diet and I am looking... 阅读全帖 |

Insulin sensitization would result in increase in RER, which shows the
elevation of carbohydrate oxidation and the concomitant reduction of fat
oxidation. Therefore, the overall energy expenditure would not be altered.
If food intake is not affected, adiposity and body weight will then be
maintained. The increased glucose taken into cells will get burned,
replacing the elevated fatty acid oxidation in diabetic state. The
biochemical mechanism underlying glucose/fatty acid fuel selection ... 阅读全帖 |

吃錯了，當然會生病！
陳俊旭醫師的健康飲食寶典
博客來網路書店金石堂、誠品等全省各大書店熱賣中
作者：陳俊旭
人造奶油的製作方法，是在每個植物油分子裡加兩個氫原子，使原本順式脂肪酸 (
cis -Fatty Acid) 變成反式脂肪酸 ( trans -Fatty Acid)。
反式脂肪酸由於分子的極性較大，油分子之間的互相吸引力較強，所以在常溫下 ( 25
℃ ) 是固態，相當穩定。
而原本的大豆油、玉米油這些植物油，在常溫下比較不穩定，呈液態。
這就像變魔術一樣，液態的植物油，加了兩個氫之後，就變成固態的氫化植物油，然後
再加點調味料、人工香料與色素，味道與模樣就跟奶油一樣... 阅读全帖 |

大家最耳熟能詳的人造奶油就是乳瑪琳。
從三十年前開始，台灣人就很盛行吃乳瑪琳，至今仍歷久不衰。另外一種氫化植物油，

linolenic fatty acid is a healthy contributor for your hearts because it is
unsaturated,but it is not stable in a high temperature such as frying.
linolenic fatty acid 在高温下（油炸）会容易降解，和转化为trans-fatty acid,so
linolenic is not good for a frying oil in restaurants and food industries.
high linolenic soy oil was reduced to a low concentration by hydrogenation
to improve the quality for frying purpose. but this processing produced
saturated trans-fat. GM soybean frying oil contains low lin and |

顾秀林
下面的论文发表的时间，是中国两种转基因水稻一种转基因玉米“终于”获得安全证书
、并引起全国转基因大辩论的时候：2010年2月。
让我们看一下摘要的简单译文（全文未见）：
“用近红外反射法，气相色谱-质谱法、高效液相色谱法、电感耦合等离子体原子发射
光谱法，并以化学计量法研究三种（分别）可抗霉菌病和抗虫的转基因水稻中重要的营
养物质成分组成（按欧共体标准），发现其营养成分组成和物理性状有非预期改变，其
中蛋白质、三种氨基酸、两种脂肪酸、两种维生素及其他数种（微量）元素出现了非预
期的构成变化。差异幅度：氨基酸20-74%，脂肪酸19-38%，维生素25-57%，（微量）元
素20-50%，蛋白质35%；植酸没有显著变化。相比于非转基因水稻，转基因水稻的营养
成分构成和物理性状的非预期改变，可能与基因的转入有关，阐明变化后的作用需要经
过更多研究。”
需要说明的是：这项研究所用的上述几种方法，全都属于常规分析方法，不是专门检测
转基因成分的高新技术，因此这项研究似乎不是针对转基因成分的（网上尚未见全文）
。所以在研究中，外源基因的表... 阅读全帖 |
