What does this picture mean to you?
There are two categories of compounds:
Substances that are formed by the chemical combination of two or more elements
Most abundant compound on Earth is
Elements have very different properties “actions/appearances” than the compounds that they form.
H = Hydrogen = gas
O = Oxygen = gas
H2O = water = liquid
The attraction of atoms that cause element to form compounds
is any member of a large class of chemical compounds whose molecules contain carbon and hydrogen
Is any member of a large class of chemical compounds of molecules that contain earths elements
Contains the earth’s element
Example: H2O water
Contains Carbon & Hydrogen always together!
Four Major Groups of Organic Compounds
“giant molecules” that are made of thousands or even hundreds of thousands of smaller molecules.
DNA and RNA
Source of short term & long term ENERGY and FOOD STORAGE
that are classified into three categories:
A sample of food containing one type of a large molecule was treated with a specific digestive enzyme. Nutrient tests performed on the resulting products showed the presence of simple sugars, only. Based on these test results, the original large molecules contained in the sample were molecules of……
linked together to form proteins
broken down into carbon dioxide and water
used as a source of energy
stored in the form of starch molecules
Building blocks :
One Glycerol molecule and three Fatty Acidmolecules
Ratio is greater than 1:2:1
include energy storage, acting as structural components of cell membranes, insulation, and participating as important signaling molecules
fats, oils and waxes
Lipids can be found in butter, olive oil, peanut oil, cheese, milk, animal fat
LIPIDS THAT ARE LIQUID ARE CALLED OIL
Greater than 2:1 ratio
Organic compounds, such as proteins and starches, are too A to diffuse into cells. Proteins are digested into B and starches are digested into C.
A-large, B-simple sugars, C-amino acids
A-small, B-simple sugars, C-amino acids
A-large, B-amino acids, C-simple sugars
A-small, B-amino acids, C-simple sugars
DO Now: Complete
“Bio-Chem. recall” numbers 1-10
Homework: Bio-Chem. Review Sheet
There are 20 different sorts of amino acid, each with slightly different properties
Proteins are made up of chains of amino acids, and are often folded up into a ball shape.
An 'average' protein has about 250 amino acids in its chain. How many different combinations are there of 250 amino acids? Although there are billions and billions of possible combinations, actually there are less than 100,000 used in the human body according to the best estimates of the scientists.
C9 H17 O4 N3
1) Structural Material (most abundant organic material within the cell)
2) Muscle Tissue
- control chemical reactions w/in organisms
4) Cell communication (hormones, neurotransmitters)
5) Immune response (antibodies)
6) Growth and repair
