Chemical recipe for apples?

My SO many years ago had come across some breakdown of an apple into chemical components, like a list of ingredients. He’s been looking for it again for quite a while, without success.

Any help? Thanks.

Something like this, perhaps?

That’s IT!!! thank you ssooooooooo much.

His sister is the quintessential ‘little bit of knowledge’ person (nice, of course), so he wanted to give her the description, do the ‘would you allow your child to eat this?’ and then tell her what it was.

thanks a billion or more!
