| 00:01 → 00:04 |
Elizabeth, please describe to us what it is we're seeing in here. |
| 00:05 → 00:08 |
This is indol-6-carboxylic acid |
| 00:08 → 00:13 |
Really? What are the uses of indol-6-carboxylic acid? |
| 00:15 → 00:17 |
Make up something! |
| 00:17 → 00:25 |
It's an amino acid used in vitamin carrying protein transport |
| 00:30 → 00:32 |
Point to the crystal in here |
| 00:34 → 00:37 |
It's right there! Can you see it? |
| 00:37 → 00:40 |
I can see it! Wow! Let's get it close. |
| 00:41 → 00:43 |
You look at it through this thing, and see it moves. |
| 00:43 → 00:45 |
You look through that? |
| 00:46 → 00:48 |
Yeah. Right here! |
| 00:48 → 00:49 |
And it swivels! |
| 00:50 → 00:52 |
It's pretty expensive... |
| 00:52 → 00:55 |
Approximately, how much is this piece of equipment worth? |
| 00:56 → 00:58 |
Probably about a couple of hundred thousand dollars. |
| 00:58 → 01:01 |
A couple of hundred thousand dollars? Just for an X-ray machine? |
| 01:01 → 01:04 |
It's not just ANY X-ray machine. |
| 01:05 → 01:07 |
Please, tell us! |
| 01:09 → 01:10 |
It's an X-ray crystallography machine. |
| 01:10 → 01:12 |
Really? |
| 01:12 → 01:15 |
You should know that. |
| 01:16 → 01:18 |
What does it do? |
| 01:18 → 01:21 |
How about YOU explain? |
| 01:24 → 01:31 |
Well, as you can see, the X-ray crystallographer shoots X-rays back and forth in these two contraptions |
| 01:32 → 01:36 |
When they shoot back and forth that determines how it looks in 3D |
| 01:36 → 01:42 |
Not just 2D...3D...three, not two..bad! |
| 01:44 → 01:46 |
So what you do - processes - Come close! |
| 01:47 → 01:48 |
We're taking a journey! |
| 01:50 → 01:54 |
You look, you twist, it shoots... |
| 01:54 → 01:56 |
...you party! |
| 01:57 → 02:04 |
And we use this light so we can see the crystal that we are using, in this case indol-6-carboxylic acid, |
| 02:04 → 02:08 |
Which as you so eloquently described is an amino acid! |
| 02:09 → 02:11 |
Now we have Siobhan to desccribe what this does! |
| 02:12 → 02:14 |
What does the X-ray diffractometer do? |
| 02:19 → 02:24 |
I can't tell you what it really does - I can make something up. It shoots X-rays at a crystal |
| 02:25 → 02:26 |
Wow! |
| 02:26 → 02:29 |
Yeah! And then it tells us the structure.... |
| 02:29 → 02:32 |
The STRUCTURE! |
| 02:32 → 02:37 |
...of the crystals, and the molecule we're studying. That's what it does. |
| 02:39 → 02:41 |
Wow! Fascinating! |
| 02:43 → 02:47 |
That was our inside look on the X-ray diffractometer. |
