Triglyceride help BIOL 1 Jan 2012

Hi,

Page 2, question 1(b)(i) asks
'A triglyceride molecule is formed by condensation. From how many molecules is this triglyceride formed?' (1 mark)

How is the answer 4 and not 3? I'm an external student and so can't ask anyone for advice and am seriously stumped!

Thanks,
Sophia

I feel so stupid now.
Ah don't worry, everything's obvious when you're told!
