Test #2 Flashcards
Monomer
a molecule of any class of compound that can be bonded to form a polymer
Polymer
materials made of long, repeating chains of molecules. Made up of many monomers joined together.
Macromolecules
Proteins, Carbohydrates, Lipids, Nucleic acids
Organic Molecules
Amino Acids, RNA, DNA, Glucose, Glycogen, Phospholipid, Glycerides, Fatty Acids, Steroids, ATP
Proteins
Made up of hundreds of amino acids
Structure of Proteins
(RCH(NH2)COOH )
Monomer of Proteins
Amino acid
Polymer of Proteins
Polypeptides and Peptides
Examples of Proteins
Enzymes, Antibodies, collagen, hemoglobin
Function of Proteins
- Form the structures of cells
- Enzymes a protein that helps catalyze (speed up) biological reactions
- Act as carriers such as the protein hemoglobin which is used to carry oxygen in red blood cells
- Muscle development
Carbohydrates
Sugars and Starches
Carbohydrates Monomer
Monosaccharide
Carbohydrates Polymer
Disaccharide and Polysaccharide
Branches of Carbohydrates
Monosaccharides- simple sugar molecule that cannot be broken down
Disaccharides- two sugar molecules that can be broken down to a simple sugar
Polysaccharides- more than two sugar molecules that can be broken down
Carbohydrates Functions
Serve as a source of short-term l energy or fuel which is then quickly used to make ATP
Carbohydrates Structure
Hexagon Shaped
2 types of Charbohydrate
Glucose, Glycogen
Lipids
Fats and Oils
Lipids Monomer
Glycerol and Fatty acid
Properties of lipids
- Do not dissolve well in water or blood
- Not as large as proteins or carbohydrates
Types of lipids
Fatty acids
Glycerides
Phospholipids
Steroids
Function of lipids
Provide insulation
Long-term energy
