Macromolecules!

Lipids

Steroids

Cholesterol

Phospholipids

Has a hydrophilic head and the tail is remote from water, just as the entire lipid. Which is another factor that makes lipids unique.

Fats

Made up of fatty acids and glycerol

Diverse group of hydrophobic molecules.

all based on the molecular sturcture.

Hydrophobic (afraid of water)

have little or no affinity for water.

made up of no polymers

Proteins

Enzymes are importants because they act as catalysts to regulate matabolism and selectively speeds up the reation in the cell without being consumed.

Has a wide range of functions.

defence on foregin substances.

movement

cellular communications

transportation

gives structual support.

storage

speeds up chemical reaction

Built from 20 different amino acids which is hundreds of amino asids long.

Accounts for more that 50% of the dry mass in a cell.

Carbohydrates

Polysaccharides

A storage material, to provide sugars for the cell. Monoaccharides make up this also.

"I will accept you"

Monosaccharides

I am a single sugar and can provide major nutrients for the cell.

Join together to create disaccharides and form a glycosidic linkage to covalently bond to form a disaccharides.

"I'm Single!"

Disaccharides

So when H2O left me us two momosaccharides came together. We met when we were joined by the condensation reation gurus..

"I'm in a realationship!

I am fuel and building material for cells

Nucleic Acids

I store and transport hereditary information.

Takes a part in creating the double helix in your DNA. Inclludes nitrogen, oxygen, carbon, and hydrogen bases which make up the DNA and RNA (A,T,C,G,U)

Polyonucleotides make up my structure. Meaning "many nucleotides"

Nitrogenous base, pentose, and a phosphate group is what mekes up a nuelcotide.

RNA

I help control protein synthesins for DNA.

DNA

Provides directions for its own replication. Also directs RNA synthesis.
