Protein

1. Amino Acids are building blocks

   • nitrogen | carbon| hydrogen| oxygen
     • low-quality
       • plant proteins
         • complimentary proteins
         • nuts & seeds
     • high-quality
       • animal proteins
         • B-12
   • 20 amino acids
     • non -essential
       • 11
     • essential
       • 9
         • carbon bacbone
           • leucine
           • isoleucine
           • valine
         • limiting amino acid
           • amino acid that stops protein synthesis
         • Measurement
           • biological value
             • nitrogen retained/nitrogen absorbed
           • chemical score
             • chemical analysis of amino acids
               • egg is gold standard
   • linked through peptide bonds
   • synthesis in the cytoplasm
   • digestion
     • stomach
       • pepsin; stomach enzyme
       • pancreas
         • inside small intestine cells
           • portal vein
             • liver
               • bloodstream
               • Broken down for energy
               • combined into proteins needed
               • stored as fat
                 • excess is excreted through kidneys

2. regulate body functions

   • blood clotting
   • fluid balance
     • protein attracts fluid into bloodstream
       • deficiency
         • edema
           • tissues swell
             • Kwashiorkor
   • hormone
   • enzyme production
   • transport substances
   • visual processes
   • cell repair
   • supply energy
