Coenzyme containing sulphur element

Post by goose_keeper » Mon Aug 15, 2005 1:07 pm

Who can tell me the follwing question:

How many and what coenzymes are containing the chemical element of sulphur(S)? What funtions are them?

Maybe I should refer to a biochemistry textbook?
But I am really confused about this problem?
Thanks for your attention?

I doubt you will find the answer to this question, since we do not yet know the structure of every coenzyme. And i doubt we have discovered all of them too...

Thanks a lot for your answer.

I know four of them, who can suggest another?
You know I cannot find the answer via google and textbook!

Another question about enzyme

Post by goose_keeper » Tue Aug 16, 2005 3:19 am

Who can tell me about the hypothetical theory of why enzyme has higer catalitic ability thanother catalysts? Or how can I find the answer?

Is it the [color=red]activation energy
that accounts?

Thanks for you attention![/color]

Enzymes reduce activation energy. http://users.rcn.com/jkimball.ma.ultran ... zymes.html

Enzymes are called a higher catalytic agents because they can catalys substances a lot quicker that other catalyst agents.
For example, if your body excesses of CO2, they will soluble CO2 with the blood plasma with this reaction:
CO2 + H2O ---> H2CO3 (carbonic acid)

In the ordinary reaction (without enzyme), this reaction will take time about hours or days...but with enzyme (Carbonic Anhidrase) the reaction will goes 18 million times faster that ordinary-without enzyme- reaction. Can you imagine how fast it is??? 8)

And for Sulphur substances, I think one of the function is to making disulphide bonds..usually, certain enzymes have it....but still IMMSMR

:oops: Thanks for your replies!

I think learing science needs great imagination which I lack very much.

Yup, science is great...don't even think the world will gonna be without science... :lol: But, unfortunately I'm lack in math.. :(
