Polymers

(meaning many parts) When a polymer being formed, two smaller molecules combined by a condensed reaction which produces a larger organic molecule plus water molecule. This specific type of reaction is called dehydration reaction because a molecule of water is removed when a monomer is added to a growing polymer.

major classes of lipids

-phospholipids -steroids -triglycerides -waxes

The process which monomers combine to form polymers is called an ____ reaction, whereas the reversible process by which a polymer is broken down into polymers is called ___.

1. dehydration, condensation , dehydration synthesis 2. hydrolysis, hydrolytic

If a chromosome contains 20% thymine, how much guanine should it have?

30%

What are the monomers found in proteins?

Amino acids

polysaccharide

Carbohydrates that are made up of more than two monosaccharides

Hydrolysis Reaction

Molecule of water is added back each time a monomer is released.

are small molecules that are linked together to form polymers, such as proteins, polysaccharides, and nucleic acids.

Monomers

Carbohydrates polymers are called?

Polysaccharides

Polymers that form when monosaccharides are linked together after a condensation (or dehydration) reaction occurs during glycosidic linkage. This is called?

Polysaccharides

Proteins are made up of chains of ____ acids
