FSHN 150 1st Edition Lecture 21Outline of Last LectureI. Exam 2 Study Guide Outline of Current LectureI. Amino AcidsII. TransaminationIII. Protein SynthesisIV. Organization of proteins: shapeV. Sickle Cell anemiaVI. Protein DenaturationVII. Protein DigestionVIII. Protein AbsorptionIX. Fate of ProteinsCurrent LectureI. Amino AcidsA. building blocks of proteinB. central atom carbonC. bound to one H atom, one amino group, one acid group, one side groupD. 20 amino acids, 11 non-essential, 9 essentialII. TransaminationA. transfer the amino group from a nonessential amino acidIII. Protein SynthesisA. DNA contains coded instructionsB. Copies of codes are transferred to the cytoplasmC. Amino acids added one at a time with aid of tRNAIV. Organization of proteins: shapeA. large molecules, amino acid sequenceB. the AA sequence in a polypeptide chain determines the proteins shape and functionThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.C. AA sequence cis the AA sequence- the backbone structureD. Secondary structure- folding of AA chainE. Tertiary structure- 3D shapeF. Quaternary structure- final 3D structure all polypeptide chainsV. Sickle Cell anemiaA. hemoglobin proteinB. 1 AA changed= abnormal shapeC. blocks the capillaries D. dominant gene in African and some mediteranean and middle eastern ethnic groupsE. malaria resistanceVI. Protein DenaturationA. loss of secondary structureB. protein shape determines function C. loss of secondary structure=loss of functionVII. Protein DigestionA. stomach-acid and pepinB. small intestine- pancreatic enzymesVIII. Protein AbsorptionA. small intestine- absorptive cellsi. need carrier molecules and energy (active)B. absorbed as AAC. portal vein to liverIX. Fate of ProteinsA. protein is not stored for future useB. dietary protein becomes body protein=amino acid poolC. excess dietary protein=fatD. too much protein, no obvious effecttoo little and you start to loose
