Reversal of deceased vital salt (6)

I believe the answer is:

folate

I'm a little stuck... Click here to teach me more about this clue!

'vital salt' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'reversal of deceased' is the wordplay.
'reversal' says the letters should be written backwards.
'deceased' becomes 'late' (I've seen this in another clue).
'of' backwards is 'fo'.
'fo'+'late'='FOLATE'

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
