| Question | Answer |
|---|---|
| Organic molecules | anything that contains C |
| Inorganic Molecules | O,K,Na,Cl,P,Ca,Zn,Fe,S |
| Biomolecules | molecules that are synthesized by leaving body that contains C atom. *Found in living things (plants, animals,virus,bacteria) |
| Types of Biomolecule | 1.carbohydrate2.lipids3.amino acids and proteins4.neucleotide |
| Carbohydrate | composed of C,H,O |
| Groups of Carbohydrate | Monosaccharide, disaccharide, polysaccharide |
| Monosaccharide | Simple Sugar Ex)glucose(from photosynthesis),fructose(from fruit, very sweet), galactose(in milk, less sweet) |
| Groups of Disaccharide | Sucrose,lactose |
| Groups of polysaccharide | Chain of monosaccharides, glycogen, starch, cellulose(found on cell wall of plants) |
| Classes of Lipids(not water soluble) | Triglycerids(fat),steroids(hormone),phospholipids,Eicosanoids(transport) |
| Triglycerids | Has glyceros and fatty acid chains*unsaturated is better than saturated |
| phospholipids | Contains phosphate group*has polar&non-polar sides*found in our membrane(bilayer) |
| Proteins | Made of Amino Acids. 20 AA groups. AA forms polymers |
| polymers | Attach and make proteins |
| How many AA does protein have | ~50 AA |
| What does the R indicate in AA? | The type of AA it is |
| Levels of protein structure | Primary(determined by sequence of AA), secondary(alpha helix & B-pheated sheath), tertiary(further floating of 2ndary), Quaternary(formation of protein with more than 1 protein chain. Ex)hemoglobin) |
| Protein SHape | Fibrous(collagen),globular(myoglobin(most of our body)) mixed(myosin) |
| Nucleotides | Carry genetic info.Transfer energy ex)ADP&ATP |
| What happens when phosphate group breaks? | We get energy from ATP |
| Nucleic Acid | polymers of nucleotides *DNA*RNA |
| DNA | Stores genetic code |
| RNA | needed for expression of genetic code |
| DNA to RNA to Protein | DNA to RNA(transcription). RNA to Protein(translation)*Doesn't happen in RBC(lacks nucleus) |
