Structure of a triglyceride molecule showing glycerol and fatty acid components.

It looks like you've uploaded a Lipid Worksheet that includes a diagram of a triglyceride molecule, composed of glycerol and a fatty acid. The task is:

> 1) Looking at the fatty acid below, copy it into the two remaining rows.

However, in your message, only one row (the bottom one) shows the fatty acid attached to glycerol. There are two blank rows above where you're supposed to copy the fatty acid structure.

Let’s break this down and solve it step by step.

🔍 Understanding the Diagram

The molecule shown is a triglyceride, which consists of:
- One glycerol backbone (three carbon chain with three -OH groups).
- Three fatty acids bonded to each -OH group via an ester linkage (though here only one fatty acid is shown).

In the image:
- The left side shows the glycerol portion.
- The right side shows one fatty acid attached to the middle carbon of glycerol via an ester bond.
- This fatty acid has:
- A carboxyl group (–COOH), but it's linked to glycerol as –COO– (ester bond).
- A long hydrocarbon chain of 8 carbons, all saturated (no double bonds), meaning every carbon is bonded to two hydrogens.

So this is a saturated fatty acid (likely octanoic acid, 8-carbon chain).

✔ Task: Copy the Fatty Acid into the Two Remaining Rows

Since only one fatty acid is drawn, and there are three positions on glycerol (top, middle, bottom), the worksheet likely wants you to copy the same fatty acid into the top and middle positions — completing the triglyceride structure.

But since the image only shows one fatty acid attached, we assume the task is to draw or copy the fatty acid structure into the other two rows, so that all three carbons of glycerol have a fatty acid attached.

📝 Step-by-Step Solution

You need to copy the fatty acid from the bottom row into the top and middle rows.

Here’s how to do it:

#### Row 1 (Top):
```
H
|
H - C - O - C(=O) - C - C - C - C - C - C - C - C
| | | | | | | | | | |
H H H H H H H H H H H
```

Wait — let’s correct the formatting. Since this is text-based, we’ll represent it clearly.

Actually, the fatty acid is:

```
O
║
C - C - C - C - C - C - C - C
| | | | | | | |
H H H H H H H H
```

But note: The first carbon is part of the carbonyl group (C=O), then 8 carbons total.

So the full fatty acid is:

- Carboxyl carbon: C=O and bonded to –CH₂–
- Then 7 more CH₂ groups
- Ends with CH₃

So it’s: CH₃(CH₂)₆COOH, but when bonded to glycerol, it becomes CH₃(CH₂)₆COO–

✔ Final Answer: Copy the Fatty Acid Structure

You should now copy the fatty acid chain (from the bottom row) to the top and middle rows, attaching it to the top and middle oxygen atoms of glycerol.

So the completed structure will look like:

```
O
║
H - C - O - C - C - C - C - C - C - C - C
/ | | | | | | | | |
H H H H H H H H H H
|
H - C - O - C - C - C - C - C - C - C - C
/ | | | | | | | | | |
H H H H H H H H H H H
|
H - C - O - C - C - C - C - C - C - C - C
/ | | | | | | | | | |
H H H H H H H H H H H
```

Wait — that's not quite right. Let's fix it.

Each fatty acid is attached via an ester bond to the oxygen of glycerol.

So the correct way to draw it is:

Correct Format (for each row):

Top Row:
```
H
|
H - C - O - C(=O) - C - C - C - C - C - C - C - C
| | | | | | | | | | | |
H H H H H H H H H H H H
```

Middle Row:
```
H
|
H - C - O - C(=O) - C - C - C - C - C - C - C - C
| | | | | | | | | | | |
H H H H H H H H H H H H
```

Bottom Row: Already given.

But wait — in reality, each fatty acid is identical unless specified otherwise. So yes, copy the same fatty acid to all three positions.

---

✔ Final Answer (What You Should Do)

Copy the fatty acid chain (the long hydrocarbon chain with the carboxyl end) into the top and middle rows, connecting it to the oxygen atoms of glycerol just like in the bottom row.

So for both the top and middle rows, draw:

```
O
║
C - C - C - C - C - C - C - C
| | | | | | | |
H H H H H H H H
```

Attached to the oxygen of the corresponding glycerol carbon.

💡 Explanation

- Triglycerides consist of three fatty acids bonded to one glycerol.
- Each fatty acid is attached via an ester bond between the carboxyl group of the fatty acid and the hydroxyl group of glycerol.
- In this case, the fatty acid is saturated (no double bonds), so it's straight and likely animal-derived.
- By copying the fatty acid to the other two positions, you’re forming a triglyceride with three identical saturated fatty acids.

✔ Summary

To complete the worksheet:

1. Copy the fatty acid chain (from the bottom row) to the top row and middle row.
2. Attach it to the oxygen of the glycerol carbon in each row.
3. Ensure the structure matches exactly: one carbonyl (C=O), followed by 8 carbons (with H’s), ending in CH₃.

This completes the triglyceride molecule.

If you were to draw it neatly, it would show three identical fatty acids attached to glycerol — forming a typical saturated triglyceride.
