Bio Chemistry question

Post by **Mik** » Wed Aug 18, 2004 10:04 pm

I haven't used my Biology knowledge in .... well....... I've never used it but I remember a lot of it.

I know that enzyme are like made of protein/ amino acid but how do they get made inside the body again?

cause I forget or was never told to being with.

Also

can they contain heavy metals, say Lead or Silver ?

my biology knowledge is below par, so i cant answer your questions, but, what excactly would this knowledge pertain to?

try wikipedia.com and type in enzymes. then see what you get.

I've refreshed my memory in regards to their contruction. The answer to what I was thinking about, lay in lead posioning but still means I'm going to have to nerf a scientific answer and just .. make some shit up.

Proteins are made by Ribosomes, these are organelles inside cells. Basically they use RNA (Through many steps involving translation etc of DNA -ie the template for the proteins) as a template for the way that the aminoacids (building blocks of protein) are strung together. Think of Proteins as a string of beads, each bead is an aminoacid, there are several different types of beads and they get strung along on a string. This string is the unformed protein now these 'beads' have certain charges (ie negative/positive) due to there side chains, These interact with the other beads forming tertiary structures there by forming your protein.

Yes some proteins do use certain metals like Lead, zinc, Magnesium etc in there structural formation. Basically the metal has a charge of it's own and it helps the protein form certain shapes, prehaps carry certain charges...etc etc.

Is that all you needed to know? or would you like to know more.

so theortically speaking the enzyme could contain silver ?

if so how would if get a source of this element .. the blood ?

wait a minuite... we use lead?

i thought lead was toxic?

(yes i know i'm stupid)

No lead is actually biologically inactive in the body but once in there it mimics the actions of other biological important metals like iron or zinc which as I mentioned early get used in other proteins (ie enzymes etc), it has a higher affinity with the protein's and displaces either Fe or Zn in favour for itself. The final product however is usually a shoddy version of the protein and it doesn't function properly causing the systems of lead poisoning.

I'm not sure of Ag as being used in metalloproteins...i'll look.

You can get silver associated with proteins... but not in a normal biological sense for humans.
Most of the silver associated proteins that I know of at least are antifungal agents (pretty sure these are produced by certain strains of bacteria...they probably secrete it and dont use it for anything but a secondary metabolite) and alot of the shit we use to treat antifungal agents run the risk of hurting us...stupid genomic homology....

It's like most heavy metals, you run the risk of throwing your protein regulation and synthesis haywire.

your rather inteligent arent you, the sorta lass that didnt forget all she learned in school

respect.

For what Mik is after that might actually work in his favor.

and yes, Les wore a labcoat to prom.

Melana didnt no u were so fukin brainy
im well impressed

I was hoping she'd answer, I knew she'd have something helpful that my own not listening in secondary school and A-level Biology and Chemistry would work against me. And I claimed I'd never use them ... boy was I wrong.

As kaos hinted that might indeed be just as good and as bad as I had orgianlly hoped for, when I think about it as long as I vaguely try to explain what I'm getting at it should be that big a deal.

I for one am glad we have our own resident crazy scientologist.
