ch6-pro Flashcards
how many essential amino acids are there and what are they
9
- Histidine
- Isoleucine
- Lueicine
- Lysine
- methionine
- phenylalanine
- thronine
- trytophan
- valine
If you dont have the correct essential amino acids what happens
the remaining non essential aas in the body go to waste
what is the flow of pro synthesis and breakdown
Amino acids from food+breakdown make pool
- Synthesis can happen from this pool
- excess nitogen in form of free amonia used to synthesize urea
what stims denaturation in protein function
- heat
- acids/bases
- heavy metals
- alcohol
what is a complete vs incomplete pro
Complete- contains all 9 essential aa
where does digestion of pros occur and what substances used
HCL- breaks down pro structure
Hydrochloric acid- activates pesin
Pepsin- brekas down pro to short polypeptides + AA
What digestion occurs in the small intestine
proteases complete digestion of proteins into sigle aa
What is the RDA (per kg and total)
0.8 per/kg
10-35%
What is protein energy malnutrition and what are the 2 serious forms
A disorder caused by inadequate intake of pro + energy
What is marasmus
grossly inadequate intake of pro
s+s- severe wasting of muscle tissue, stunted brain dev, weakened immune function
What is kwashiorkor
Extremely low pro intake often seen in children in developing countries
s+s- weight loss, muscle wasting, edema, slowed growth+dev
