**Lipid Structure and Properties**

In the image provided, we can observe the structural representation of a lipid molecule. Below the structural formula, several questions are intended to assess understanding of lipid biochemistry.

**Molecular Structure Details:**
1. The molecule depicted in the image is a triglyceride composed of a glycerol backbone linked to three fatty acid chains through ester bonds.
   - The first fatty acid chain (topmost) consists of a long hydrocarbon chain with a terminal carboxyl group (O=C-OH).
   - The second fatty acid chain (middle) features three double bonds located at the 9th, 12th, and 15th carbon atoms, denoted by the positions of the double bonds and the omega (ω) designation.
   - The third fatty acid chain (bottom) is another long hydrocarbon chain similar to the first.

**Questions about the Molecule:**
1. **Identify this molecule (1):**
   - This molecule is a triglyceride, a type of lipid.

2. **This molecule is formed when 1 molecule of ___________ reacts with 3 molecules of ___________:**
   - This molecule is formed when 1 molecule of glycerol reacts with 3 molecules of fatty acids.

3. **Will it be a solid or liquid at room temperature? Why? Justify your answer (2):**
   - The physical state at room temperature can be determined by the presence of double bonds in the fatty acid chains. Unsaturated fatty acids (those with double bonds) usually lower the melting point, making the triglyceride more likely to be a liquid. In this case, given the presence of double bonds in at least one of the fatty acid chains, it is likely to be a liquid at room temperature.

4. **In nature, will it assume a cis or trans confirmation?**:
   - In nature, the double bonds in unsaturated fatty acids most commonly assume the cis configuration, where the hydrogen atoms attached to the carbon atoms of the double bond are on the same side, causing a bend in the hydrocarbon chain.

Understanding the structure and properties of lipids is essential in biochemistry as they play critical roles in cell membrane structure, energy storage, and signaling.
