What is needed to produce protein? - 🧠ANSWER ✔✔AA (building blocks)
ATP (energy)
From what two places does the rumen microbes get AA? - 🧠ANSWER
✔✔1. AA from digesting feeds
2. Use AA produced by themselves
What are keto-acids? what is it a product of? - 🧠ANSWER ✔✔Compounds
leaving ketone and acid
Product of glycolysis, TCA, and fermentation
(fermentation of carbohydrates should provide keto acids for production of
new amino acids, and provide energy for ATP for microbial protein
synthesis)

,What 2 things in feed would provide amino groups to amino acids? -
🧠ANSWER ✔✔1. Amino acids
2. NPN (urea)
if animals ingest too much urea and don't have enough keto acids to trap it
into new amino acids, what will happen - 🧠ANSWER ✔✔Ammonia will
diffuse into the blood
What happens when ammonia is in the blood? - 🧠ANSWER ✔✔highly toxic
- liver converts to urea
What condition happens when the liver can't convert enough ammonia into
urea? - 🧠ANSWER ✔✔hyperammonemia
What happens when the body goes into hyperammonemia? and how do
you prevent it? - 🧠ANSWER ✔✔disrupts CNS,
1. prevent overfeeding of urea
2. feed quick fermenting carbs
What is urea recycling? and by what 2 processes? - 🧠ANSWER ✔✔urea in
blood returns to rumen
1. through rumen wall

,2. with saliva
What are 2 advantages of urea recycling? and what is a way to increase
urea recycling? - 🧠ANSWER ✔✔1. NH3 has a second chance to be used
for amino acid synthesis
2. Less urea excreted in urine
protect amino acid from microbes in a fat capsule
How are lipids measured? - 🧠ANSWER ✔✔in EE: ether estracts
Are lipids hydrophobic or hydrophilic? Soluble in H2O? Soluble in organic
compounds? - 🧠ANSWER ✔✔Hydrophobic, No, ether
What are 4 forms of lipids? - 🧠ANSWER ✔✔Fat, oil, fatty acids, cholesterol
Do lipids have more or less hydrogens than carbohydrates? Does this
mean more or less energy? - 🧠ANSWER ✔✔More, more
(in the body carbohydrates, glycogen, are bound to 2x water. Fat is not
bound to water and therefore has 7x more energy)
What are 6 functions of fat in the body? - 🧠ANSWER ✔✔1. energy source
2. cell membrane

, 3. hormones and vitamin D
4. absorption of vitamins
5. insulate body
6. cushion organs
What are the 2 classifications for lipids? - 🧠ANSWER ✔✔glycerol based
and non-glycerol based
Glycerol - 🧠ANSWER ✔✔3 carbon molecule (backbone for lipids)
Triglycerides - 🧠ANSWER ✔✔3 fatty acids bound to 1 glycerol
Glycolipids - 🧠ANSWER ✔✔1 or more sugar unit bound to glycerol
phospholipids - 🧠ANSWER ✔✔1 phosphate group bound to glycerol
Fatty acids - 🧠ANSWER ✔✔carboxyl group and carbohydrogen chain
What are the 2 terminal ends of fatty acids? - 🧠ANSWER ✔✔carboxyl and
methyl ends
What are 2 systems to classify fatty acids? - 🧠ANSWER ✔✔Length and
number of double bonds
