CARBON COMPOUNDS
The chemistry of Carbon The chemistry of carbon is very important
to living things Carbon has 4 electrons available for
bonding Can form 4 covalent bonds Carbon can bond with many elements
including hydrogen, oxygen, phosphorus, and sulfur
All living things have carbon in them
The Chemistry of Carbon Carbon can also bond with itself Because carbon can bond with itself, it
can form REALLY long chains
Carbon Chains
Macromolecules Some molecules are so large, they are
known as macromolecules, or “giant molecules”
We’ve talked about these before… …carbohydrates, lipids, proteins, amino
acid, nucleic acid Let’s look at more specifics
Carbohydrates Made up of Carbon, Hydrogen, and
Oxygen Main source of energy for living things Sugars are “carbs” When broken down, provide energy Many living things store extra sugar is
stored as starch
Carb: Simple sugars Can be called monosaccarides and simple
sugars PS. Mono means 1
Examples include: glucose and galactose (found in milk) and fructose (found in fruits)
Table sugar, sucrose, is made up of both glucose and fructose and is a disaccharide PS. Di means two.
Complex Carbs Large macromolecules formed when simple
sugars join together Many animals store extra sugar as a complex
carb (glycogen) When glucose in your blood runs low,
glycogen is broken down into glucose and enters the blood stream
Plants use a different complex carb, starch, to store extra sugar.
Plants also make a complex carb called cellulose
Cellulose Cellulose gives plants their strength and
rigidity. Cellulose is the major part of wood and
paper
Lipids Fats, oils, and waxes are common lipids Lipids are macromolecules that generally
do not dissolve in water Made of H and C Some lipids store energy Others form biological membranes Some produce waterproof coverings on
cells and tissues https://

Saturated vs. Unsaturated Many lipids are formed when a glycerol
molecule joins with a fatty acid Bonds are the “—” between the letters
If there are all single bonds, it is considered “saturated”
If there is a double-bond with any of the carbon, it is “unsaturated”
Lipids that have “unsaturated fatty acids are liquid at room temperature ex.: olive oil
Saturated vs. Unsaturated
Saturated/Unsaturated
Nucleic Acid Macromolecule containing H, O, N, C, P Store and transmit genetic information
Two types-RNA ribonucleic acid Contains ribose
DNA- deoxyribonucleic Contains deoxyribose
Proteins Micromolecules that contain: N, H, C, O https://

rates, others form important parts in a cell, while others help fight disease
Amino Acids are joined in long chains according to instructions in the DNA
