The glycerol contains alcohol as functional group.
Explanation - The beta oxidation of fatty acids cause the breakdown of lipids and leads to release of fatty acids as well as glycerol. The glycerol is a polyhydroxy alcohol. It means that it has more than one -OH (hydroxy) groups.
The figure attached below shows the breakdown of triglyceride
into fatty acids and glycerol.

Triglycerides can be broken down by hydrolysis reactions to glycerol and fatty acid chains in the digestive tract. Glycerol is easily converted to 1 phosphoglyceraldehyde also known as PGAL. Using your knowledge about how aerobic cellular respiration functions, explain how from this original glycerol molecule how many ATP’s are formed in this process. Make sure you include explanations where each ATP is made.

Which of the following statements are true? 1- Triacylglycerols (triglycerides) are composed of fatty acid residues and glycerol. 2- Saturated fats are more likely than unsaturated fats to be solid at room temperature. 3- Triacylglycerols (triglycerides) are carboxylic acids. 4- Saturated fats have lower melting points than do unsaturated fats. 5- Fats that contain more saturated fatty acid residues than unsaturated fatty acid residues are more likely to be solid at room temperature.

Which of the statements are true? Fats that contain more unsaturated fatty acid residues than saturated fatty acid residues are more likely to be liquid at room temperature. Tracleucerols (triglycerides) always contain three identical fatty acids. Unsaturated fats have higher melting points than saturated fats. Triacylglycerols (triglycerides) are composed of fatty acid residues and glycerol. Unsaturated fats are more likely than saturated fats to be liquid at room temperature.
