Carbon Compounds Chapter 2 sec. 3
carbon Organic compounds contain carbon
Macromolecules Monomer -simplest form Polymers -repeating monomers Macromolecules -made up of polymers
Molecules of life 4 essential organic compounds essential to life 1.Carbohydrates 2.Lipids 3.Proteins 4.Nucleic acids
Carbohydrates Composed of carbon, hydrogen and oxygen Used as main source of energy 1.Monosaccharides 2.Disaccharides 3.Polysaccharides
Monosaccharides “Simple sugar” Ratio of 1:2:1 (CH 2 O) Glucose C 6 H 12 O 6 Fructose = fruit Galactose = milk
Disaccharides Double sugar = 2 monosaccharides Sucrose = glucose + fructose
Polysaccharide Composed of 3 or more monosaccharides EX. Glycogen – many glucose molecules Cellulose and starch
Lipids Large nonpolar organic molecules that do not dissolve in water Large # carbon and hydrogen bonds
Fatty acids Unbranched carbon chains that make up most lipids 1.Triglycerides 2.Phospholipids 3.Waxes
Triglycerides 3 fatty acids and a alcohol glycerol Saturated (shortening and fats) (solids) Unsaturated (energy) (liquids)
Phospholipids 2 fatty acids joined to glycerol Cell membrane = lipid bilayer
Wax Long fatty acid chain joined to long alcohol chain Waterproofing – plants and animals
Nucleic Acids Very large and complex Store important info in cell 1)Nucleic acids 2)Nucleotides 3)DNA
Structure of DNA One Nucleotide consists of: 1.Phosphate group 2.Sugar (deoxyribose) 3.Nucleic Acid
Nucleic Acids DNA and RNA = deoxyribonucleic acid polymers of nucleotides
Proteins Carbon,hydrogen,oxygen and nitrogen Building blocks of proteins
Amino Acids 20 different types 1)Amino acid 2)Dipeptide 3)polypeptide
Dipeptides 2 amino acids bonded together Peptide bond = bond between amino acids
Polypeptide Long chains of amino acids
Enzymes Catalyst in reactions Enzymes are proteins Ex. Digestive enzymes
Enzymes and Proteins Fit “lock and key” to substrate to produce product (very specific for what they bond too)
Bio 1 Carbohydrates, Lipids, Proteins, and Nucleic Acids
Lesson Overview 2.3 Carbon Compounds.
Chapter 3: Biochemistry
3.3 Molecules of Life.
Vocabulary 16. Lipid Monosaccharide 17. Nucleotide Active site DNA
3-2: MOLECULES OF LIFE There are 4 classes of organic compounds essential to life: Carbohydrates Proteins Lipids Nucleic Acids Each of these compounds.
ORGANIC COMPOUNDS Chapter 2 Section 3.
Energetics. Do Now-QUIZ on separate sheet of paper- do not talk or use notes Place your HW on your desk 1.Analyze why Carbon is unique 2.Define polymer.
Ch. 3.2 Molecules of Life: Macromolecules. Carbohydrates: carbon, hydrogen, and oxygen. 1:2:1 Monomer = monosaccharide (simple sugar) (CH 2 O) n where.
Section 6.3 – Life Substances
Biomolecules The Molecules of Life
Biochemistry Chapter 3. Water polar compound one end is slightly negative while the other is slightly positive polar compound one end is slightly.
Chapter 3 Objectives Section 1 Carbon Compounds
Organic compounds Carbon compounds
Biochemistry Chapter 3.
Organic Compounds Carbohydrates, Lipids, Proteins & Nucleic Acids.
Chapter 3 Biochemistry.
Organic = contains carbon ALL living things contain carbon So ALL living things are organic.
