NUSC 1165 Lecture Notes - Lecture 25: Essential Amino Acid, Gluconeogenesis, Sodium-Potassium Alloy
Document Summary
Important because red blood cells can only use glucose for energy. Ways to assess protein status: serum albumin, analyze blood, want levels less than 3. 5, calculate nitrogen balance. If negative, indicates they are protein deficient: uun (urinary urea nitrogen) + 4g tells us how much nitrogen we are losing a day. If uun=10g, + 4g = 14g: convert to protein, 14*6. 25=87. 5 grams of protein/ day, *** on exam (uun+4)*6. 25 = how much protein you need, general recommendation of protein for public: 0. 8g* kg of body weight (lbs*2. 2=kg) *no added benefit from excess protein, ends up in urine, if anything puts extra pressure on your kidney.

Limiting amino acid is eaa5, since it is the lowest essential amino acid. Higher the biological value of food, the higher the level of protein.
