Urm.. watched Mulan last night at a friend's house! Haven't seen it for ages and it was great. Downloaded multiple songs onto iPod. Physics taken over life. End report, less cheering-up than initially intended but an attempt. :trytofly:

The fact that the super cool 'I'll make a man out of you' is sung by Donny Osmond is great.

awh physics

I like 'a girl worth fighting for' - so funny - 'chicken , beef, pork' heh :biggrin:

Lion King, it rocks, no arguments, end of! :p:

Anyways I'd better go revise chemistry, got two exams tomorrow, havent revised yet :confused:

Had a discussion in our English class a couple of months ago where we concluded that the Lion King is actually based loosely on Hamlet, with a disney ending...

Is it just me, or is this the second (possibly third??) time this thread has gone onto the subject of favourite Disney film?

(Lion King all the way! :biggrin:

Are there any ~~weirdos~~ biologists here? :p:

I need major help with food science, basically its a module I have to do for my chemistry course, and I know nothing. Its all biology. Can someone please explain what the primary, secondary and tertiary structures of proteins are and how they are maintained?

Ill rep whoever does tomorrow, I would post this in the bio forum but Im scared of them :p:

Primary structure: The sequence of amino acids in the protein

Secondary structure: The way the polypeptide sequence folds. Can either be an alpha helix or a beta pleated sheet. Secondary structure is held together by hydrogen bonds.

Tertiary structure: The overall shape of the protein. Held together by a variety of bonds, i.e. hydrogen bonds, disulphide bridges and ionic bonds.

Oh, and there's nothing wrong with biologists! :p:

I'd have to agree, we're spoilt for choice! Disney films are the best.

I think Bambi has to be my favourite, and fern gully is also pretty cool, the Pagemaster! although that blond **** stars in it... nope im staying with bambi :smile:

Very minimal explanation:

Primary: order of amino acids in the polypeptide chain. Maintained by peptide bonds: C=O-N-H (obv the N is bonded to the C)

Secondary: alpha helices and beta sheets. Alpha helices are right-handed and maintained by hydrogen bonding between the amino group of a peptide bond and the carboxyl group of another peptide bond four residues away.
Beta sheets: polypeptide chains are linked together in a side-by-side configuration, again by H-bonding. Beta sheets can be either parallel, where the adjacent polypeptide strands extend in the same direction, or anti-parallel (the strands extend in opposite directions).

Tertiary: further folding and coiling of the protein, determined between interactions between amino-acid side chains. Hydrophobic interactions place the amino acids containing non-polar R groups towards the centre of the molecule. In many proteins the covalent disulphide bonds that form between the sulphydryl (SH) groups on cysteine residues make an important contribution to tertiary structure. (Blatantly nicked from Scholar). Prosthetic groups (e.g. haem groups on haemoglobin) are incorporated at this stage (I think, or it may be quaternary).

Quaternary: joining together of 2+ polypeptide subunits, forming a larger protein. e.g. haemoglobin = 4 units, 2 of alpha and 2 of beta globin.

Enjoy.

Check out this quote from the H&R forums :laugh:

What good will that do? Putting a number against your penis won't make her feel more comfortable. "Actually I'm less than one standard deviation from the mean!" What kind of turn-on is that...
