Shimer-Macromolecules

Lipids, carbohydrates, proteins, and nucleic acids represent the four major macromolecules essential to life. Lipids, such as fats and oils, are crucial for energy storage, cushioning organs, and insulating the body.

Shimer-Macromolecules

Shimer-Macromolecules

Lipids

Fats
Saturated Fats

Solid at Room Temperature

Long, Straight Chains

No C=C double bonds

All C's bonded to H's

Unsaturated Fats

(Actual Chain is Bent)

Vegetable Oils

Liquid at Room Temperature

Plant and Fish Fats

Bend in chain

C=C double bonds

Non-Polar and Hydrophobic
Fats, Oils, Phosphlipids, Steroids
Structure of a Phospholipid

Phospholipids are found in the cell membrane

Energy Storage, Cushions Organs, Insulates Body
Triglyceride

Proteins

When a protein loses its shape it is called DENATURING
Temperature and pH can denature a protein
Peptide bonds are the special bonds that keep them together
The R group changes between them to make them unique
The shape allows proteins to do their jobs
There are four different layers of Proteins
Muscle, Skin, Hair, Enzymes
Hormones, Movement in Muscles, Immune System, ENZYMES, Transport
Amino Acid

Carbohydrates

Cellulose in Nature: Structure in plants (cell walls) Cellulose in American Diet: Fiber
Pants-Starch, Animal-Glycogen
Glucose,Fructose, Sucrose, Maltose
Sugars end with -OSE
Sugars, Starches, Cellulose, Glycogen
Carbon Ring(Hexagon)
Energy Storage, Quick Energy, Structure
Carbon, Hydrogen, Oxygen
Monosaccharide

Nucleic Acids

Phosphate Group, Nucleotide, and a Pentose Sugar make up a Nucleic Acid
Stores and Transmits Hereditary Information
RNA and DNA
RNA is a single nucleotide chain and DNA is a double nucleotide chain (double helix)
Carbon, Hydrogen, Oxygen, AND Nitrogen
Nucleotide
