Alkaloid gives a good answer, alkaloids does not (getting hung up on an -s)

[cbizon]

When you search for Alkaloid, you get the clique for CHEBI:22315, which has Alkaloid as a preferred name, and Alkaloids as a synonym.

But if you search for Akaloids, that CHEBI clique is nowhere to be found and the top result is:

"curie": "UMLS:C3653469",
"label": "Alkaloids, excl. rauwolfia, antihypertensives",
"synonyms": [
  "Alkaloids, excl. rauwolfia",
  "Alkaloids, excl. rauwolfia, antihypertensives"
],

I think we might need to think about de-pluralizing
