The enzymes that generally calalyse the hydrolysis of proteins and lipids are both hydrolases. Protease is the general enzyme that breaks the peptide bonds between amino acids in proteins, in hydrolysis. Lipase is the general enzyme that breaks the ester bonds between fatty acids and gylcerol in a trigylceride, during hydrolysis. But like you have stated, they do get more specific than thier generalised catagories.

From my limited experience, I can vouch on a small scale that the polularity is dropping. For someone that usually has a high aptitude for science, I lasted for aprox. 1 week in my AS Physics class, and in that time he only covered basic mechanics! Safe to say I was joined by many other students.

I thought that RSC membership is reserved for graduates? Excuse me if I'm wrong!

If I'm reading correctly, then you can't find the excess ammount unless stated, as it is an excess, but you can find the ammount reacted. http://www.wpbschoolhouse.btinternet.co.uk/page06/Mtestsnotes/ExtraVolCalcs1.htm I found working through these questions rather useful in exam preperation!

Green Tea :]

Can't really answer your question, but what sort of speeds are you getting using Torpark? When testing it the other day, it was extremely slow - not worth the hassle.

Reminds me of the film 'Urban Ledgends'

Haha! Great to see you back! I'm not as loved as you here, but hopefully I can find a little bit more time for sfn these days.

Hehe, just read this on slashdot. I'm not going to stop downloading mp3's, but good song non the less!

Just reviewing my choices for AS's next year, well month, but you know what I mean. Was thinking of taking chemistry, physics, computing, and another one, maybe maths. I dont really have an interest in maths (I know I should do!), but figured it may have its use for a level phys and chem, and science at the degree level. Can anyone provide some support for this? Also, I would be greatful for some recomendations of reading material for the physics and chemistry a-levels. I know the basics of the sylebuses, but always like to be ahead! Thanks!

Eek! Can't wait until next thursday for GCSE results!!

I managed to get through the usually horrendous English Literature exam today, considering my lack of knowledge of "of mice and men" and the bastard anthology...! It turns out the two essay questions I answered, I have aleady done them in one of many practice exams! Oh how I hate English!!

I don't think your that alond here Cloud, atleast theres me here doing GCSE's! I'm also hoping for AA science, which I think is quite achievable - if only I could get the biology right! How come you are doing your modules this late on? I have my first two exams next week, English Lit (EEK!!) and RS.

was it a cartridge with a chip on it? if so you cannot refill them types, as the chip on them works out the ammount of ink remaining, AFAIK.

What type of pen does Nash use when he is writing on the windows throughout the movie? Thanks.

The easiest and safest method i know of is fractional freezing. From my notes: -store bought hydrogen peroxide is usually 3% H2O2, 97% H20 -water freezes at 0 degrees (obv!) -H2O2 freezes at -11 degrees depending on your freezer, if you freeze the solution, and drain it off, the drained liquid will be relatively pure H2O2.

You seem to have quite an interest in chemistry, never thought about getting on a chemistry course in your highschool?

Yes that also works as a catalyst for the breakdown, all the methods discussed here are the only ones i know from chemistry. Weve also done it with potassium permanganate.

I can understand your confusion then from that explanation considering what you have said, sorry if i seemed abit rude! In the electrolysis of water, at the cathode (negative electrode) hydrogen gas (h2) is formed, and at the anode (positive electrode) oxygen gas (o2) is formed.

You cant electrolyse water and expect to make lead dioxide!! Before, if you would like me to write an explanation, what level of chemistry are you currently at?

Certain elements are reffered to as diatomic, meaning they exist in nature as a molecule containing two of the same atoms (http://en.wikipedia.org/wiki/Diatomic_molecule). The diatomic elements are H, O, F, Br, I, N, Cl, and At but that is usually discounted from its ammount naturally occuring. Subscript numbers are a representation of the chemical formula, the ratio of elements in a molecule. Superscript numbers are reserved for ions, more the charge that a certain element/compound has. (http://en.wikipedia.org/wiki/Chemical_formula). Why do you want to make these gases? edit: superscript numbers to the left of an elements symbol refers to the isotope of the element, which doesnt have an awful lot to do with chemistry.

I got this email forwarded today, wasnt sure about the accuracy of the content but didnt dismiss it as i dont usually get spam from family. Seems like crap to me, just wanted others opinions. I obiously know what dioxins are, but this! Cheers

BBC and BBC Worldwide are two different companys. BBC is strictly a uk company.

I think weve had enough conversation of nutmeg over the past week thanks!!

Put this in about me: <br /> <style type="text/css"><br /> .Main { position:absolute; left:50%; top:125px; width:800px; z-index:1; margin-left:-400px; padding:0px; border:0px; background-color:transparent;}<br /> </style><br /> And this in who id like to meet: <br /> <DIV class="Main"> <table style="width:800px; height:600px; cellpadding:0px; cellspacing:0px; border:2px solid silver; background-color:ffffff;}"> <tr> <td valign="top"> <!-- Your HTML Here! --> </td> </tr> </table> </DIV><br /> I had this saved in a text file awhile ago so dont credit me for it. Basically its a CSS class that covers up your profile so you cannot see it. My guess is you can copy all your HTML from your site into where ive left the comment. Worth a try as ive not tested it. I dont know how youdd intergrate comments etc though.
