glykoaineissa

Could you clarify what you mean by glykoaineissa? The Finnish term could refer to several related concepts (for example glykoaineet as a general class of sugar-containing substances, glykoalkaloidit, glykoamiinit/amino-sugar compounds, or glycoproteiinien/glykanien alueeseen liittyviä aineita). A precise interpretation will help me write an accurate, concise wiki-style article under 300 words.
