Characteristics of water
Adhesion- Different particles that attach themselves to one another
Cohesion- Molecular attraction in which elements are bonded
Polarity- The dipole-dipole intermolecular forces between the two pole located at the north and south of the molecule, each positive and negative.
Heat storage- water has one of the highest thermal capacities Heat capacity
pH scale- used to measure acidic or basic a substance is.
Macromolecules: large molecules made up of smaller organic molecules.
there are four types of macromolecules:
carbohydrates,lipids, proteins, nucleic acids.
Carbohydrates: a large biological macromolecules that is made up of only carbon, hydrogen and oxygen.
Lipids- Any substances contains fat and oils,there job is to store energy (Saturated, unsaturated)
Carbohydrate- Any group of organic compounds
Three types of Carbohydrates
Monosaccharides- Table sugar, provides energy for red blood cells, brain and rest of the nervous system
Disaccharides- Sucrose, provides the body with energy for mental and physical needs
Polysaccharides- Starch, used as fuel for all cells
Proteins- Made of amino acids and the building materials for other living cells operates a majority
Nucleic Acid- Group of complex compounds in all living organisms and viruses, DNA, RNA and ATP, help transfer genetic information
Enzymes- A substance that causes a chemical reaction, speeds up the rate of chemical reactions (Metabolic, digestive and food)
