A salt or ester of malic acid, an organic compound found in many fruits.
In biochemistry, malate refers to the anion or salt of malic acid, a key intermediate in metabolic cycles like the Krebs (citric acid) cycle and the Calvin cycle in plants.
Linguistics
Semantic Notes
"Malate" is almost exclusively used in chemistry and biochemistry contexts. It is a countable noun when referring to specific salts (e.g., magnesium malate). It is not used in general English.

Examples
By CEFR Level
- Malate is found in many fruits and contributes to their sour taste.
- The supplement contained calcium and magnesium malate for better absorption.
- The enzyme malate dehydrogenase catalyses the oxidation of malate to oxaloacetate in the Krebs cycle.
- In C4 plants, malate is shuttled from mesophyll cells to bundle-sheath cells to concentrate CO2.
Learning
Memory Aids
Mnemonic
Think of a 'MAY' tree (like an apple tree) that's LATE to bear fruit, because it needs the compound MALATE to help its apples taste sour (malic acid gives sour taste).
Conceptual Metaphor
A CURRENCY OF ENERGY: Malate is often conceptualized as a form of stored chemical energy or a transport molecule that 'carries' energy or carbon between different parts of a cell or metabolic process.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'меланин' (melanin, a pigment).
- May be incorrectly parsed as 'mal-' (bad) + '-ate' (verb ending).
Common Mistakes
- Misspelling as 'malete' or 'malaite'.
- Incorrect pronunciation with stress on the second syllable (e.g., /məˈleɪt/).
- Using it as a verb (to malate something).

FAQ
Frequently Asked Questions
No. The prefix 'mal-' in 'malate' comes from 'malic acid', which is derived from the Latin 'malum' (apple). It has no relation to the Latin 'malus' (bad, evil) found in 'malicious'.
Only if the essay is specifically about biochemistry, nutrition, or food science. It is far too technical for general contexts.
It means the product contains magnesium bound to malic acid, a form of magnesium supplement that some claim is well-absorbed.
No, 'malate' is strictly a noun. The related verb would be something like 'esterify to form malate' or 'produce malate'.
