- Biological Molecules
- Lipids
- roles: energy storage mol, bilayer of cell mem-ctrls what comes in & out
- emulsion test: dslve solid smple in ethanol, + equal vol H2O, shake, +ive...milky-white emul forms
- tryglyce.: cond reac=ester bond+H2O mol, energy storage mol, glycerol+3 F.A,insol.so dont affect T. H.phobic tail,H.phyllic head.long h.carbon tail contains lots chem energy
- Phospholip.: bilayer of cell mem. 2 F.A+phosph grp+glycerol, bilayer cent=h.phob, barrier
- Carbs
- Pollysacch.: POLYMER monosacc bond via glyco.
- Starch
- Iodine Test: + iodine dissolved in pottas.iodide soln, +ive...BROWNY/ORANGE -- BLUE/BLACK
- Glycogen: energy,a-glucose,compact,branched,quick energy release&gd store
- Cellulose: long,unbranched,B-glucose,straight chains,H-bnds,struct.supp,eg.cell wall
- Starch
- Monosacch.: MONOMER
- Glucose: a-gluc..DDUD b-gluc..UDUD
- Fructose
- Galactose
- Disacch.: 2 monosacc, glyco bond
- Maltose: a-gluc+a-gluc
- Lactose: Gluc+Galac
- Red-Sugar test: add BLU BenRe,heat,+ive...BRICK RED PPT COPPER (I) OXIDE.blu.gree.yel.ora,b.red
- Sucrose: gluc+fruct
- Non-Red sugar test: red.sug.test= -ive: + dil.HCL, heat, neut w/ Na hydcarbonate....RedSug test AGAIN
- HCL to break into monosacch's
- Non-Red sugar test: red.sug.test= -ive: + dil.HCL, heat, neut w/ Na hydcarbonate....RedSug test AGAIN
- Pollysacch.: POLYMER monosacc bond via glyco.
- Protiens
- Biuret Test: NaHydrox soln=make alkaline soln, + Cu(II)sulfate, shake,+ive....BLU--VIOLET
- Enzymes: speed up chem reac by acting and bio catalysts
- Inhibition: comp inhib-block AS..noncomp inhib-binds away from AS alters AS shape
- Activation Energy: Enzy lower this in reaction
- Specific Active site: only 1 comlement subs will fit
- Induced fit: as subs binds AS changes shape slightly
- ESC
- Induced fit: as subs binds AS changes shape slightly
- Enzyme Action
- Conc
- pH: pH opt exceeded, enzy denature
- Temp: temp opt exceeded, enzy denat
- Amino Acid: MONOMER, dipep=2AA,polypep=2+AA, prot=1+polyp
- Primary/2ndary/tertiary/quaternary Struct: P-seq AA in polypep chain..S-Hbond, aHelix coil, bpleated sheet..T-Hbond,disulf bridges, ionic bonds..Q-sevral polypep chains hld by bonds
- Nucleic Acids
- Nucleotides: polynucleotides..polymer
- ATP: Adenosine TriPhosphate..breaks into ADP
- DNA: DeoxyriboNucleic Acid-store genet info, grow&develop, DEOXYribos sug
- Semicons Replication: DNA helicase, Hbonds, Polynucleotid, unwind, expose bases, OG single strand, template, comp base pair, free nucleotides, cond reaction, DNA polym, form Hbonds, 2 DNA mols, 1 OG strand&1 new.
- RNA: RiboNucleic Acid-protien synthesis, ribose sug
- Nucleotides: polynucleotides..polymer
- Water
- Polar, metabolite, Hi L.H.V, buffer temp, solvent, cohesion
- Inorganic Ions
- Fe ions-haemaglobin, H ions-pH, Na ions-trnsprt glucose&AA across cell mem., Phospht ions- component of ATP&DNA
- Condensat/Hydrolysis: cond- 2 mols join, MAKES glyco bond + 1 mol water. Hyd- braks chemical bond, USES 1 water mol
- Lipids
