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
