Answer: Docosahexaenoic acid (DHA)

Flashcard 6: Starter F75 has 75 kcal and _____ g protein per 100 mL

Flashcard 7: 1. Identify → _____ 2. Nutritional values → 43.2% protein, Deficient in methionine and cysteine, NPU 55, 432 kcal/100gm

Answer: Soyabean

Extra: Soybeans are a rich source of plant-based protein and are widely used in clinical nutrition and public health programs. While they are deficient in sulfur-containing amino acids (methionine and cysteine), they are rich in lysine, making them an excellent complement to cereal proteins.

Flashcard 8: _____ is an "internal" indicator of protein quality

Answer: Biological value (BV)

Extra: NPU (Net Protein Utilization) is an "external" indicator because it measures nitrogen retained relative to nitrogen **intake**. NPU = BV × Digestibility coefficient

Flashcard 9: _____ has the maximum NPU(net protein utilisation)

Answer: egg

Extra: 

Flashcard 10: _____ is the best protein indicator
