1. Monosaccharide
  • Have molecular formula CH2O
  • Common monosaccharide is Glucose C6H12O6 

2. Disaccharide 
  • Formed when a dehydration reaction joins two monosaccharides 
  • The covalent bond is called glycosidic linkage 

3. Polysaccharide
  • Have storage and structural roles
  • The architecture and functions are determined by its sugar monomers and the positions of its glycosidic linkages

  • have two polynucleotides spiralling around, forming a double felix
  • backbones run in opposite 3' - 5' directions from each other, referred as antiparallel
  • Certain bases paired up and form hydrogen bond, this is called complementary base pairing
  • Adenine (A) always with Thymine (T) and Guanine (G) always with Cytosine (C)

  • Single-stranded 
  • Complementary base pairing can occur between two RNA molecules 
  • Thymine is replaced by Uracil (U)
  • Variable in form

- Fats
  • Fats are constructed from two types of smaller molecules (glycerol and fatty acids)
  • 3 fatty acids joined to glycerol by an ester linkage, creating a triacylglycerol or triglyceride
  • Fats have saturated fats and unsaturated fats which saturated fats is saturated fatty acid with no double bonds while unsaturated fats is unsaturated fatty acids have one or more bonds
*hydrogenation is a process of converting unsaturated fats to saturated fats by adding hydrogen

-Phospholipids 
  • two fatty acids and phospholipids attached to glycerol
  • two fatty acid tail which is hydrophobic while phospholipid and its attachment is hydrophilic 

- Steroid 
  • Are lipid characterized by a carbon skeleton consisting of four fused rings 
  • Cholesterol is a type of steroid

1. Primary 
  • Set of 20 amino acids
  • Is its unique sequence of amino acids

2. Secondary 
  • The coils and folds result from hydrogen bonds
  • a helix & B pleated sheet

3. Tertiary 
  • These interactions include hydrogen bonds, ionic bonds, hydrophobic interactions and van der Waals interactions
  • A mix of both a helix and B pleated sheet

4. Quaternary 
  • results when two or more polypeptide chains form one macromolecule
