Morphology
The form is compositional (adjective + "acid"), so a learner who knows "acid" can infer this is a type of acid; however "aspartic" is a technical, language-specific chemical label whose referent (an amino acid) is not deducible from the ordinary meaning of the adjective. Because the structure signals a kind of acid but the crucial lexical element is specialized and requires domain knowledge, the item is only partially transparent to a B1 learner.
Etymology
The chemical name aspartic acid comes from the vegetable asparagus, because scientists first found this acid in asparagus juice. That's why the name points to its original source and helps you remember it is a natural 'building block of proteins' found in foods.
