当这几个词的意思翻译为:脂肪,蛋白质,矿物质,维生素.这些词的时候,是既可数又不可数的.当他们指的是物质本身的时候是不可数的.但是如果表示种类的话是可数的.
fats,proteins,minerals and vitamins这里的意思是各种脂肪,蛋白质,矿物质和维生素.所以后面加s.楼上说脂肪只有一种是错误的.脂肪共有三种类型:1、饱和脂肪酸(存在于动物性脂肪中,如肉、蛋、牛奶等);2、单不饱和脂肪酸(花生油,橄榄油等);3、多不饱和脂肪酸(葵花籽油,菜子油,核桃油等).这里的脂肪不是说身体组织,而是从食物中摄取的脂肪种类.
如果单纯说某一种脂肪,蛋白质,矿物质和维生素的话就不可数

英语翻译
However,the preferred handling of peptides over protein faces challenges concerning the higher complexity of the proteome sample and the wider dynamic range,where thousands of peptides,with very similar m ass to charge (m/z) ratios,are present at different levels of abundance.Considering that the human proteome (containing approximately 20,000 genes) yields millions of peptides,it becomes clear that this task is not a trivial exercise .Therefore,methods exhibiting high resolving power are required to maximize the separation of peptides before the m ass spectrometric analysis.Improved resolving power can help decrease competition between peptides during ionization and reduce the likelihood of ion sup-pression,increasing the possibility for the detection of low-abundance peptides (and the protein of origin).

A polymer is a large molecule (macromolecule) composed of repeating structural units typically connected by covalent chemical bonds.
Proteins (also known as polypeptides) are organic compounds made of amino acids arranged in a linear chain and folded into a globular form. The amino acids,which are universally containing both amine and carboxyl functional groups, in a polymer chain are joined together by the peptide bonds between the carboxyl and amino groups of adjacent amino acid residues. One amino acide can be considered as a unit that protein consists of hundreds of single units. So they are labeled polymers as their another name "polypeptides".
Since there are no repeating units in the lipid structure, they cannot be naturally treated as polymers.

阅读理解.
The high-protein,low-carbohydrate (碳水化合物) diets many people turn to for weight loss might have
potentially harmful long-term effects on the colon,a small study indicates.
In the study,UK researchers found that a protein-heavy,low-carb diet created certain changes in the colon
that could contribute to colon cancer risk The study itself does not show whether high-protein diets really raise
the risk of any colon diseases,but the findings raise that possibility.
Diets relatively high in protein and lower in carbs have been shown to help heavy people lose weight."People
should not be discouraged from losing weight," Dr Flint said.However,he added,they should make sure that
any weight loss plan includes adequate amounts of fiber and a high protein intake over months to years might
have ill effects on the colon.
The findings are based on 17 overweight men who followed three short-term diets:a one-week menu plan
to keep their weight; a four-week high-protein diet with reasonable amounts of carbohydrates; and a four-week
high-protein diet low in carbs.
On average,the study found when the men were on the high-protein diets,they had higher levels of
substances known as N-nitroso compounds (亚硝基化合物) and other metabolites (代谢物) that have been
linked to cancer.And when they were on the high-protein,low-carb diet,they had lowered amounts of fiber-
originated compounds thought to be protective against cancer.
Exactly what those changes might mean for a person's health is not clear.But Flint said that the findings
suggest that people should be cautious about consuming too much protein and too little fiber over a long period.
In general,experts recommend that adults get about 28 grams of fiber per day-though it's not known whether
that's enough for someone on a high-protein weight-loss diet.

GTPase Activating Proteins,or GAPs,or GTPase Accelerating Proteins is a family of regulatory proteins whose members can bind to activated G proteins and stimulate their GTPase activity with the result of terminating the signaling event.
GAPs mediate switching a G protein on and off.G proteins are switched from the active,GTP-bound form to the inactive,GDP-bound form by hydrolysis of the GTP through intrinsic GTPase-activity.It can be reverted (switching the G protein on again) by guanine nucleotide exchange factors (GEFs).Only the active state of the G protein can transduce a signal to a reaction chain.
The ability of GAPs to turn off G proteins depends on their local concentration in the cell,and on their own activity state.Both of these are frequently under regulation of one or more signaling pathways,and modified by binding to other regulatory proteins or specific lipids,or by phosphorylation.
The GAPs that act on small GTP-binding proteins of the Ras superfamily have conserved structures and use similar mechanisms,whereas most of those that act on alpha subunits of heterotrimeric G proteins belong to a distinct family,the RGS protein family.
An example of a GTPase is the monomer,Ran,which is found in the cytosol as well as the nucleus.Hydrolysis of GTP by Ran is thought to provide the energy needed to transport nuclear proteins into the cell.Ran is turned on or off by GEFs and GAPs,respectively.

英语翻译
原文是
Proteins are more stable in water when their hydrophobic side chains are aggregated in the protein interior rather than solvated by the aqueous medium.(在水中,当蛋白质的疏水侧链聚集在其内部而不是溶解在水溶液中时,蛋白质更稳定)Because water molecules interact more strongly with each other than with the nonpolar side chains of a protein,the side chains are forced to associate with one another,causing the polypeptide chain to collapse into a more compact molten globule.(因为水分子之间的相互作用要比水同蛋白质的非极性侧链之间的相互作用强烈得多,导致多肽链相互聚集,形成更加紧密的“融球”)
这些是理解下面翻译的上文.
接下来请翻译:
The decrease in entropy of the polypeptide is more than offset by the increase in solvent entropy;this overall increase in entropy provides the major driving force for protein folding.
前面的那句话怎么翻译呢?是被动结构吗?
懂物化的或者生化的还可以回答下,为什么在蛋白质折叠过程中,多肽链的熵减少了而溶液的熵增加了?
我重新理解了下,这句话应该是被动结构,is offset by,是被抵消的意思,is more than offset by,是后者能更多地抵消前者的意思。所以我觉得这句话翻译成“多肽链熵的减少更多地被溶液熵的增加所抵消”或者“多肽链熵的减少不足以抵消溶液熵的增加”似乎更好。

英语翻译Enrichment of protein synthesis in transition-stage SAMs
英语翻译
Enrichment of protein synthesis in transition-stage SAMs is consistent with previous findings that enhanced ribosome function is required to establish a shoot meristem
(Weijers et al.,2001; Tzafrir et al.,2004; reviewed in Byrne,2009).Transcriptsencoding the maize RIBOSOMAL PROTEIN S5A and S5B (RPS5A,also known as Arabidopsis
MINUTE-LIKE1 [AML1];RPS5B) are both upregulated in transition-stage embryos compared with the L14-stage SAMs.Development of aml1 mutant embryos is arrested at the globular stage in Arabidopsis before the meristem is established (Weijers et al.,2001).
