Question

one way the types of lipids differ is their chemical structures. the model shows the chemical structure of a fat. fats are also known as triglycerides. triglycerides store energy in the body.
chemical structure of stearin
select the true statements.
triglycerides contain phosphorus atoms.
fats store energy in the body.
triglycerides have carbon atoms arranged in long chains.

Explanation:

1. For "Triglycerides contain phosphorus atoms": Looking at the chemical structure of stearin (a triglyceride), the atoms present are C, H, O. There is no phosphorus (P) atom, so this statement is false.
2. For "Fats store energy in the body": The text states "Triglycerides (fats) store energy in the body", so this statement is true.
3. For "Triglycerides have carbon atoms arranged in long chains": The structure shows long chains of carbon atoms (e.g., the fatty acid chains with multiple C atoms), so this statement is true.

So the true statements are "Fats store energy in the body" and "Triglycerides have carbon atoms arranged in long chains".

Answer:

• Fats store energy in the body.
• Triglycerides have carbon atoms arranged in long chains.
