Answer:

The trivial name for 2-hydroxypropane-1,2,3-tricarboxylic acid

Explanation:

A weak tribasic tricarboxylic acid (contains 3 separate carboxyl groups) that occurs naturally in citrus fruits (it exists as around 50 g/litre in pure lemon juice).

Applications include food flavouring, acidification, and also as a sequesterant (citrate ions readily form complexes with metal cations).
