Biology Biology
Organic Chemistry• All living things have Carbon in them • Orgo- a class in college where all the
exercises include carbon chains • Organic compounds: 4 groups found in all
living things– Carbohydrates– Fats/ lipids– Proteins– Nucleic acids
Carbs/ Fats / Proteins: All have C,H,O
• Carbohydrates: main source of energy– Simple- quick burst of energy
(snickers)– Complex –provide more energy_ slow
release (brown rice)
All CARBS…– Contain C H O – Starch: extra sugar stored as this– Mono-saccharides ex) glucose,
galactose, fructose– Poly-saccharides ex) glycogen
Proteins• Function? Repair…
– Meat , fish, beans, tofu …… protein bars
– Macromolecule– N C H O
Proteins– Are amino acid polymers….
• Macromolecules: are giant molecules in cells made during polymerization
• Smaller units= monomers• When they join together- polymers• So are amino acids made of proteins or vice
versa?
Lipids• Fats/ Oils/ Waxes (non-polar) :
source of energy too…last– Don’t dissolve in water– Mostly C and H atoms– lipids= fatty acid + glycerol– Cell membrane
Lipids– Saturated fats: ex. Red meat, eggs,
dairy– Unsaturated fats: ex. Olive oil, corn
oil, avocado

• atherosclerosis
Nucleic Acids: DNA, RNA
Nucleic Acids• DNA and RNA (deoxy-ribose-nucleic acid)• Macromolecules/ polymers
– Monomers that make them up=nucelotides
• Contain…H, O, N, C, P• RNA and nucleotides• Nucleotide: sugar+phosphate+nitrogen
