Levels of protein structure: primary, secondary, tertiary, quotiary Primary- just the amino acid structure- basic- AACTCGC Secondary- initial folding- beta pleated sheets: zig zag- alpha helix Tertiary- comelete 3D structure- Quatiary- Poly peptide chain- amino acids linked together Sickle cell- blood disorder, red blood cells disorder only in African American population. KNOW DEFINITIONS AND ENTERPRITATIONS Chaperones aid in folding Dna- phosphorous A T G C Lipis- CH Protein carb/ Amino acid- CHON Nucleic acid- CHONP NH2- amino SH- sulfhydryl C-OH carbon Essential- fats lips, amino acids. Require 20 acids to func, only 11 natural- need food to get other 9 PH of fountain is 7 on Monday and 9 on Thursday and 4 on Friday how are the concentrations of hydrogen and OH changing through the week- Monday – thurday= PH is increase more basic- 10 ^2 – OH is increase by 10^-2 Thursday to Friday- decrease more acidic PH + POH= 14 Taxononmy- king Philip came over for great spaghetti Kingdom, phylum, class, order, family, genus, species

Unformatted text preview: Know scientific method and known vs. alternative 1- Peptide bond and sequence of amino acids 2- Hydrogen bonds, alpha helix of beta plated sheets 3- R groups final folded shape 4- Only some make it here 2 or more strands associate with each other Denaturation- loss of some levels of protein. Caused by salt, ph Sickle cell- C # 6 in protein AA strand VAL sub causes abnormal binding and release Protein folding: chaperoning Abnormal fold, found in Alzheimers and Parkinsons Protein function: 1- Structure 2- Defense 3- Transport 4- Contracting 5- Signaling 20 amino acids only 9 are essential Amino acids are the building blocks of protein not nucleic acid Electronegitivity- attracts electrons a lot Covalent- bonds between carbons Polar covalent- bonds between hydrogen and oxygen 2 diff sugars- RNA-ribos DNA- Deoxyribos- missing oxygen DNA- Tiamine Lipids- fats- non polar-insoluable in H2O- Amino acids- have carboxyl and R Group Primary-...
