Kyllästettyjä

Kyllästettyjä is Finnish for saturated things in the plural partitive form of the adjective past participle kyllästetty, which comes from the verb kyllästää (to saturate). It is used to describe substances that have been saturated, most often fats or fatty acids. The form kyllästettyjä appears before a plural noun in the partitive case, for example kyllästettyjä rasvoja (saturated fats) or kyllästettyjä öljyjä (saturated oils).

In nutrition and food science, the term is commonly used with rasvat and rasvahapot to distinguish saturated fats from unsaturated fats. Saturated fats are characterized by having no carbon–carbon double bonds in their fatty acid chains, which affects their physical properties, such as being solid at room temperature. Dietary guidelines typically address the intake of kyllästetyt rasvat due to associations with cardiovascular risk factors, especially when consumed in excess. Common dietary sources of saturated fats include certain animal fats (such as butter and meat fats) and some plant-based fats (such as coconut and palm oils).

In chemistry, kyllästettyjä can describe molecules that have been saturated, meaning they have no reactive double bonds remaining in their structure. The term is generic and can apply to various substances, not only fats, whenever a saturation process has occurred.

Usage note: kyllästettyjä is a grammatical form used in front of a plural noun in the partitive case. It is not typically a stand-alone noun; its meaning relies on the accompanying noun, such as rasvoja, öljyjä, or fatty acids, to specify what has been saturated.
