Attempt This Question
Not attemptedCorrect Answer: (c) A is true but R is false
Dietary fatty acids (especially the essential ω-3 linolenic and ω-6 linoleic acids) must be supplied through food, so including them in a balanced diet is desirable – making Assertion true. However, human cells can synthesise most saturated and monounsaturated fatty acids de-novo; only the two essential poly-unsaturated series cannot be formed because the necessary desaturase enzymes are absent. Therefore the Reason is false. ([pmc.ncbi.nlm.nih.gov](https://pmc.ncbi.nlm.nih.gov/articles/PMC11879921/?utm_source=openai))
