compressibility
4 types of Biomolecules
Carbohydrates
Proteins
Nucleic Acid
Lipids
Most common molecule
Carbohydrates
Primary energy source of our body
Carbohydrates
What is the building block of carbohydrates?
Monosaccharides
Also known as simple sugar
Monosaccharides
Three types of simple sugar
Glucose (blood sugar)
Fructose (fruit sugar)
Galactose (found in milk with glucose)
Also known as double sugars
Disaccharides
When you add two glucose together
Maltose (malt sugar)
-Found in beers
When you combined galactose and glucose
Lactose (milk sugar)
Fructose + glucose
Sucrose
Also known as complex sugars
Polysaccharides
-Used for storage in plants
-They provide a “quick” form of energy for the human body
Starch
-Used for energy storage in animals
-it stores emergency energy in the liver and muscles when the body doesn’t need glucose
Glycogen
-found in plants
-gives us fiber
Cellulose
Forms the exoskeleton of certain insects and crustaceans
Chitin
2 test for carbohydrates
Iodine test
Benedicts test
Test used to determine the presence of starch in materials
Iodine test
Test used for simple carbohydrates
Benedicts test
Bodybuilding molecules which help us grow
Transport molecules in and out of the cell
Protein
Building blocks of proteins
Amino acid
Test for protein
Biuret Test
Biomolecular components of hereditary materials are present in the DNA
Nucleic Acids
They store more energy than carbohydrates and proteins
Lipids
