Cards

Term
4 classes of large biological molecules
Definition
  • carbohydrates
  • lipids
  • protiens
  • nucleic acids
Term
Macromolecules
Definition
large molecules composed of thousands of covalently conencted atoms
Term
Polymers
Definition
  • chain like molecules that consist of many building blocks
  • macromolecueles are polymers
Term
Monomers
Definition
  • small building blocks that make up polymers
Term
Enzymes
Definition

Specialized marcomolecules that speed up chemical reaction

 

  • snythesize= to make
  • catalyze = to breakdown
Term
Dehydration Reaction
Definition

two monomers bond due to the loss of water between the molecules

Term
Hydrolysis
Definition
reverse of dehydration reaction. Polymers are disassymbled to monomers by hydrolysis
Term
Carbohydrates
Definition
  • include sugars and polymers of sugars
  • comes in forms of monosaccharides, disaccharides, and polysaccharides
  • is a macromolecule and one of the large biological molecules
Term

Monosaccharides

Definition
  • simplist form  of carbohydrates, also called single sugars
  • are the bulding blocks of polysaccarides
  • have molecule fomulas that are in multiples of CH20
  • classified by: location of the carboxyl group, number of carbons in the carbon skeleton
  • serves as a major fuel for cells and as raw materials for building molecules
