Hydrogenovanými

Hydrogenovanými is a Czech grammatical form used as the instrumental plural of the past passive participle hydrogenovaný, derived from the verb hydrogenovat, meaning to hydrogenate. It describes something that has undergone hydrogenation and is typically used in phrases that express means or accompaniment with a plural noun in the instrumental case.

In chemistry and related fields, hydrogenation refers to the chemical reaction in which hydrogen is added to organic compounds, often across carbon–carbon double bonds, usually in the presence of a catalyst. Substances produced by this process are described as hydrogenované látky or hydrogenované sloučeniny. The word form hydrogenovanými is applied to nouns in the instrumental plural, indicating the thing with which or by which the action is performed or described, for example with or by the hydrogenated products.

Common usage examples include: s hydrogenovanými tuky (with hydrogenated fats) and s hydrogenovanými oleji (with hydrogenated oils). The instrumental plural form is used regardless of the gender of the noun it accompanies, aligning the participle to agree with the plural noun in instrumental case. In general Czech usage, many writers also use the simpler form hydrogenované when referring to plural nouns in nominative or other cases, reserving hydrogenovanými for explicit instrumental constructions.
