Elements Of Lipids
|
CHO
carbon, hydrogen, oxygen |
|
Ratio Of Carbon to Hydrogen
|
Lipids do not have a 1:2 carbon to hydrogen ratio
|
|
Examples of Lipids
|
fats, oils, and waxes
|
|
Energy per gram
|
Carbohydrates release 4 calories/1 gram
Lipids release 9 calories/1 gram |
|
Functions Of Lipids
|
Stored Energy
Cushion Organs Provide Insulation Are a component of the cell membrane Ear wax traps dirt, microbes, and dust Plants leaves have a waxy cuticle layer for protection and to prevent water loss Skin produces oils in the sebaceous layer to prevent from cracking |
|
Lipid Structure
|
Contain 1 glycerol and 3 fatty acids
|
|
Elements of Protein
|
CHON
carbon, hydrogen, oxygen, and nitrogen |
|
Proteins are macromolecules
|
macromolecules- large molecules made up of chains of smaller molecules
|
|
Proteins are made of amino acids
|
amino acids- the simplest unit of proteins; there are 20 essential amino acids in living organisms
|
|
Amino Acids
|
The 20 amino acids are similar in structure except for something called the "R-group". Each structure has a hydrogen group, an amino group, and a carboxyl group that are identical. The "R-group" is different for each of the 20 amino acids.
|
|
Dehydration Synthesis
|
amino acids are bonded together by peptide bonds to form proteins. when two amino acids combine a water molecule is released.
|
|
Function of Protein
|
to build muscles
growth and repair component of cell membrane used to make enzymes hormones antibodies hemoglobin neurotransmitters |
|
Organization of proteins
|
amino acids (simplest)
dieptide (two amino acids bonded together) polypeptide (many amino acids bonded together) protein (many polypeptides bonded together and held together by hydrogen bonds) |
|
Elements of Nucleic Acids
|
CHONPS
carbons, hydrogen, oxygen, nitrogen, phosphorous, and sulfur |
|
Nucleic Acids
|
DNA- deoxyribonucleic acid
RNA- ribonucleic acid |
|
Function of Nucleic Acids
|
to hold and pass on the genetic information of the cell
|
|
Shape of DNA
|
arranged in the form of a double helix and ultimately make up the chromosome
|
