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) |
