fatty acid
A chemical compound that is a basic building block of fats and oils. A main distinction is made between saturated, monounsaturated, and polyunsaturated fatty acids, which are important for the metabolism of living organisms.
Omega-3 ist eine essenzielle Fettsäure, die der Körper nicht selbst herstellen kann.
Omega-3 is an essential fatty acid that the body cannot produce itself.
The word is a compound of 'Fett' (fat) and 'Säure' (acid). The 's' in between is a linking element that connects the two words. So the meaning is literally an acid that is a component of fat.
Avocados enthalten viele gesunde Fette und somit auch Fettsäuren.
Avocados contain many healthy fats and therefore also fatty acids.
'Fettsäure' (fatty acid) is a technical term from chemistry, biology, and nutrition science. In normal everyday life, people usually speak more generally of 'Fetten' (fats).
Im Biologieunterricht haben wir über die Struktur von Fettsäuren gesprochen.
In biology class, we talked about the structure of fatty acids.
In connection with nutrition, fatty acids are often described more precisely. Typical combinations are 'gesättigte Fettsäuren' (saturated fatty acids), 'ungesättigte Fettsäuren' (unsaturated fatty acids), and 'essenzielle Fettsäuren' (essential fatty acids).
Lachs ist reich an mehrfach ungesättigten Fettsäuren.
Salmon is rich in polyunsaturated fatty acids.
acid / acidity
'die Säure' and 'die Fettsäure' can be confused because both words come from chemistry and contain 'Säure' (acid). 'Säure' is the more general term for a certain type of chemical substance, for example 'Salzsäure' (hydrochloric acid) or 'Zitronensäure' (citric acid). 'Fettsäure' is more specific: it is a building block of fats and oils and is often mentioned in relation to nutrition, the body, and metabolism. So not every acid is a fatty acid. If you are speaking generally about acidic substances or chemistry, 'Säure' fits. If it is about fat, oil, or nutrition, 'Fettsäure' is more precise.
Omega-3 ist eine Fettsäure, die in manchen Fischsorten vorkommt.
Omega-3 is a fatty acid that occurs in some types of fish.
Im Chemieunterricht lernen wir, wie eine Säure mit Metall reagiert.
In chemistry class, we learn how an acid reacts with metal.
