FNH 250 Lecture Notes - Lecture 8: Sickle-Cell Disease, Hemoglobin, Peptide
Document Summary
Protein are recycled so that we can use them more than one protein turnover. You are absorbing single amino acids, not proteins or peptides. Excess of amino acids leads to high urea production. While nut is in their name, peanuts are in fact legumes. Peanuts actually grow underground, as opposed to nuts like walnuts, almonds, etc. that grow on trees. H-bonds and disulphide bonds stabilize the protein 3d structure/configuration. 3d shape of a polypeptide stabilized by side chain interaction (non- covalent or disulfide bonds) and interactions between side chains and backbone atoms. Replacement of one of the amino acids in the beta chain of hemoglobin leads to sickle cell anemia. Food allergy: allergic only to pro (not cho or fat) Animal foods give a bit more of protein as a component of energy (kcal) than plant foods. Tuna most protein-sensed food (>85% of kcal as pro) High intake of protein can lead to kidney damage (high urea production)
