Chapter 5--polymers And Monomers Flashcards
Monomers
Small building blocks of molecules
Polymer
Chain of monomers
Dehydrogen reaction
Takes away water
Hydrolysis reaction
Adds water in the reaction
Carbohydrates
Made of sugars
Monosaccharide
Single sugar. Carbohydrate’s monomer
Polysaccharide
Many sugars. Carbohydrate’s polymer. Responsible for storage and structure
Disaccharide
2 sugars
Glycosidic linkage
Alpha and beta linkages between carbohydrates
Alpha glycosidic linkage
On the same side of the molecule. In plant cells. An example if a Cis-molecule
Beta glycosidic linkage
Different sides of the molecule. In animal cells. An example of a trans-molecule
Lipids
Class of large biological molecules which DO NOT FORM POLYMERS
Glycerol
Three carbons with a hydroxyl group attached to each carbon
Fatty acid
Carboxyl group attached to large carbon groups
Ester linkage
The link between fats
Saturated fat
As many hydrogens as possible (i.e. No double bonds)
Unsaturated fat
Has a double bond (or multiple), so it doesn’t have all the hydrogens that it could
Phospholipid
Two fatty acids and a phosphate attached to a glycerol. The phosphate group is hydrophilic, tails are hydrophobic
Enzyme
Protein that acts as a catalyst. It makes and breaks bonds
Peptide linkages
The link between proteins
Amino acid
Monomer of protein. 20 types. Classified by their r group
Primary structure (1°)
Depends on the amino acid sequence
Secondary structure (2°)
α helix or pleats
Tertiary structure (3°)
Interaction of 2°
