17
Q

What can triglycerides be broken down into?

A

1 glycerol

3 fatty acids

18
Q

How is triglyceride broken down?

A

By 3 hydrolysis reactions

19
Q

What is needed to break down the triglyceride?

A

3 water molecules

3 oxygen atoms and 6 hydrogen atoms are added to the triglyceride

This breaks the 3 ester bonds, for,img glycerol and 3 fatty acids
