Chemistry of Life
Chemicals are responsible for directing virtually all of our bodily functions. Bodily functions are directed by chemicals.
Understanding the basic chemical reactions that occur in the body is essential.
Understanding the basic concepts of biochemistry is vital.
A question for you!
What is the primary difference between organic and inorganic compounds?
Organic CompoundsOrganic Compounds Inorganic CompoundsInorganic Compounds
LivingContain C-C and C-
H BondsExamples:
CarbohydratesLipids, Proteins,
and Nucleic Acids
NonlivingDoes not contain C-
C and C-H bondsExamples: water,
temperature, soil, and wind
Compounds
Answer !
Inorganic compounds do not contain carbon-carbon bonds or carbon-hydrogen bonds.
[water and some acids, bases, and salts]
Organic compounds contain carbon and include carbon-carbon bonds and/or carbon-hydrogen bonds.
The human body has both types of compounds!
Inorganic compounds
Water Water is a solvent (liquid into which solutes are
dissolved), forming aqueous solutions in the body
Water is involved in chemical reactions Dehydration synthesis (water removed) Hydrolysis ( water added)
Water Qualities
Polar moleculeComposed of hydrogen and oxygenHigh surface tensionHigh heat of vaporizationExpands when it freezesBody composed of mainly waterChemical reactions participation

Organic Chemistry
Major types found in body: Carbohydrates Lipids Proteins Nucleic acids
Note: Table 2-3 on page 32 gives examples, and functions of each.
CarbohydratesCarbohydrates LipidsLipids
Source of energy3 types:Monosaccharide: one
simple sugar (glucose, fructose, galactose)
Disaccharide: two simple sugars (sucrose)
Polysaccharide: many simple sugars (starch and glycogen)
Composed of one glycerol and 3 fatty acids
Fats and OilsExample:
Triglyceride and Phospholipid

Seminar Topic: Tissue Types
Bill is a 17 year old high school student that plays soccer for his high school team. During yesterday’s game, he fell while scoring the game winning goal. He is not sure, but he thought he heard a snapping sound in his arm. Discuss the 4 tissue types and how they may be involved in his injury.
Question for You!
What are the four types of tissues?
4 Tissue Types:
EpithelialConnectiveMuscleNervous
Epithelial Tissue

Muscle and Nervous

urinary tracts
Nervous: Nerve cells (Glia)
Connective Tissue
Most abundant tissue in the bodyTable 3-7 page 61Types include: Areolar, Adipose, Dense
fibrous, Bone, Cartilage, Blood, Hematopoietic
