广州中山大学发现:水稻转基因后生化成分有重大改变
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

我的体系其实不会遇到这么极端的情况,其实就是很单一的L构型的芳香氨基酸,是纯

来自主题: Medicine版 - GNC的Whey和Protein有什么区别?
Most protein supplements come from soybeans or whey. The major factors are
* inclusion of all essential amino acids
* matching of amino acid composition to normal bodily need
* taste, digestibility
In addition, soy protein isolates have some additional reported health
benefits (control of cholesterol and osteoprosis)
It's important not to overdose or become dehydrated. Your brother should
probably consult his doctor first, too.

Thanks!
1st time 2.7 mm, they gave me a possibility of down syndrome of 1/270 ( I
was 27 at that time), I decided to not do the amino test.But when I did the
ultra at 20 wks, they said nuchal fold is big and is an independent test of
nuchal transluency, then re-calculate the possibility to 1/100. I finally
did at the amino at 22 wks.
2nd time 9.9 mm (a big hygroma)
this time 1.8 mm
It was said that NT cutoff is around 2.5-3 mm

来自主题: NextGeneration版 - 关于唐筛!
如果你只是关注唐氏综合症的话,可以等大B超结果出来再做,做大B超的时候,特别注
意观察孩子的小手,如果他的手一直是攥着的,不能张开并且手指自由的活动,就比较
危险了,唐氏儿做大B超的时候,手基本上都是张不开的。
但是如果你也担心孩子有其它基因上的问题,就直接做amino吧,毕竟amino查的不仅是
唐氏,还可以查出不少其它问题。

来自主题: Parenting版 - roundup会不会对小孩健康不好
I am a chemist.
Roundup targets an enzyme in plant. The corresponding enzyme is MISSING in
human. Therefore, in theory, you can drink roundup without any side effect.
For those parents who are more interested in science, roundup targets the
aromatic amino acid biosynthesis pathway in plants. We, human, lack similar
biological pathway and obtain aromatic amino acids from foods. Therefore,
roundup should be safe if accidentally spilled on your skin or mouth, as
long as you eat nutritious food or ... 阅读全帖

Collagen /ˈkɒlədʒɨn/ is the main structural protein

connective tissue, it is the most abundant protein in mammals,[3] making up

elongated fibrils, is mostly found in fibrous tissues such as tendons,
ligaments and skin, and is also abundant in corneas, cartilage, bones, blood

Chemistry
Aspartame is the methyl ester of the dipeptide of the natural amino acids L-
aspartic acid and L-phenylalanine. Under strongly acidic or alkaline
conditions, aspartame may generate methanol(甲醇) by hydrolysis. Under
more severe conditions, the peptide bonds are also hydrolyzed, resulting in
the free amino acids.[4]
For some markets, aspartame is manufactured from phenylalanine produced by a
genetically modified strain of E. coli,[5][6] a bacterium
