Macromolecules

Large molecules with thousands of atoms

Dehydration Reaction

Reaction where monomers are connected through a covalent bond that is formed when a water molecule is removed

Hydrolysis

The process where polymers are disassembled by the addition of a water molecule

Monosaccharide

a molecule that has the formula of C H and O that is a multiple of CH2O

Aldose

a classification of sugar where the carboxyl group is at the end of the carbon chain

Ketose

a classification of sugar where the carboxyl group is is in the within the carbon chain

Disaccharide

2 monosaccarides joined by a glucoside linkage

Glycoside Linkage

a covalent bond fromed between 2 monosaccarides by a dehydration reaction

Polysaccaride

a macromolecule comprised of 100's-1000's of monosaccarides

Lipids

hydrophobic molecules that aren't polymers and aren't big enough to be macromolecules

Fatty acid

a long carbon chain with a functional carboxyl group at one end

Esther linkage

The bond that links fatty acids with the glycerol backbone. It is a bond between the hydroxyl and carboxyl to make a tricylglycerol

Fats

Large molecules (but not macromolecules) assembled from 3 fatty acids and a glycerol backbone

Phospholipids

Lipids that compose the cell membranes; made of 2 fatty acids, glycerol backbone, and a lead group

Steriods

lipids with a carbon skeleton of 4 fused rings

Steric Constraints

The physical constraints of bonding. Monomers can't fit together to bond

Polypeptide

polymers of amino acids

Proteins

Biologically functioning molecules of one or more polypeptides, folded in a specific 3-D shape

Amino Acid

Organic molecule with an amino group and carboxyl group. It is comprised of an alpha carbon surrounded by an amino group, carboxyl group, H atom and R group

Peptide Bond

The covalent bond that attaches the carboxyl group of one amino acid to the amino group of the next through a dehydration reaction

Primary Structure

The linked unique series of amino acids in a protein

Secondary Structure

coils and folds that result from hydrogen bonds between the backbone (Alpha and Beta helix)

Tertiary Structure

Overall shape of a polypeptide resulting from the interactions between side chains. 2 kinds: hydrophobic side chains moving to the shelter of the center, and disulfide bonds between the sulfers of cysteine monomers

Quantiary Structure

Overall protein structure that results from multiple polypeptide sub-units combining

Denaturation

The bonds of a protein fail and it loses shape and is destroyed

Chaperonins

Protein molecules that assist in the folding of other proteins

Nucleic Acids

polymers of DNA material

Nucleotides

Monomers of DNA material

Gene

unit of inheritance that programs the amino acid sequence of polypeptide

Nuclecic Acids

macromolecules that exist as polymers called polynucleotides

Nucleotide

Monomers that make up a nucleic acid. Has 3 parts: Nitrogenous base, 5 carbon sugar (pentose), and 1 or more phosphate groups

Pyrimidine

Nitrogenous base type that has 1 6 ring of Carbon and Nitrogen (Cytosine, Thymine, Uracil)

Purine

Nitrogenous base with a 6 membered ring with a five membered ring (Adenine and Guanine)
