Carbon Hydrogen Nitrogen Oxygen Phosphorus Sulfur
Trace elements
Elements we need in small amounts
Carbon atoms
Can bond 4 other atoms
For short strong bonds
Can make double bonds
Can make long chains and rings
Which is stronger cabin chains or rings
Chains
Monomers
Single molecules that makeup all living things
Monosaccharide
Single sugars
Glycerol
Alcohol used to connect things
Fatty acids
Make fats and oils
Amino acids
Make proteins
Nucleotides
Found is nucleus
Make DNA and RNA
Monosaccharides elements
Type of carbohydrate
Made only carbon hydrogen and oxygen
Carbon/water
Examples of monosaccharides
Glucose-made by photosynthesis
Fructose-fruit sugar
Disaccharide
2 monosaccharides bonded together
Example of disaccharide
Sucrose- table sugar
Polysaccharide
Many monosaccharides bonded together
Glycerol(alcohol)
3 bonded monomers
Triglyceride
Glycerol bonded to 3 fatty acids
Fatty acid made of
Acid followed by a hydrocarbon chain
Chain of hydrogen and oxygen
Fatty acid-water
Hydrophobic
Saturated fatty acids
Straight chains
Unsaturated fatty acids
Bent chains
Rings
Amino acids made of
1Carbon 1 hydrogen An amino group nh3 An acid (Carbon oxygen oxygen hydrogen) An r group (random)
How many different R groups
20
How many amino acids
20
Are amino acids important
Some are essential
You can’t just make them you need to incorporate them in your diet
Nucleotides made of
One 5carbon sugar
Phosphate
Nitrogen containing base
5 different nitrogen bases
Guanine Cytosine Adenine Thymine Uracil
DNA nitrogen bases
Guanine
Thymine
Cytosine
Adenine
RNA bases
Uracil
DNA bases end in
Ine
Two different 5 Carbon sugars are
Ribose in RNA (OH)
Deoxyribose in DNA (H)
Largest monomer
Nucleotides
Largest monomer actually includes monosaccharide
Phosphate made of
Phosphate and oxygen
Characteristics of phosphate
Hydrophilic
Phosphate part likes water
Macromolecules this monomer can make
Phospholipid
Condensation dehydration rxn
Remove water (in form of h from one molecule and OH from another) In order to stick molecules together
Polymers/macromolecules
Monomers bordered together to make polymers
Chemical reactions that bond monomers together is condensation dehydration rxn
5 macro monomers
Polysaccharides Lipids Phospholipids Proteins Nucleic acids
Polysaccharides made up of
Made up of MANY single sugars
Carbohydrates
Polysaccharides examples
Starch - how plants store glucose
Glycogen-how animals store glucose
Cellulose- makes plant cell walls and is out fiber in our diet (fiber is indigestible)
All are made of chains of glucose
Lipids made up of
Fatty acids and glycerol
Lipids-water
Hydrophobic
Lipid examples
Fats- solid at room temp. (Saturated fatty acid) stored energy in animals
Oils- liquid at room temp. (Unsaturated fatty acid) stored energy in plants
Waxes- used to water proof
Steroids- hormones help with homeostasis
Phospholipids made of
Glycerol
2 fatty acids
1 phosphate
Phospholipids -water
Phosphate head hydrophilic
Hydrocarbon tail
Hydrophobic
Phospholipids example
Cell membrane
Proteins made of

Protein quality
3D shape
Most muscle is protein
Most enzymes are proteins
