Biochemical Engineering Flashcards
Bond between monosaccharides
glycosidic bonds
Primary level of protein structure
amino acid sequence
Secondary level of protein sturcture
Alpha helix coil or beta sheet
Tertiary protein structure
fold of proteins
Quaternary structure of proteins
Polypeptide chains
Protein chains that are easily soluble in water, found in enzymes, spherical conformation
Globular
Protein chains that are found as parallel polypeptide chains in long sheets, water insoluble, tough, stretchy
Fibrous
Types of inhibition
Competitive, non-competitive
Inhibition type where the binding site is blocked
Competitive
Inhibition type that changes the shape of enzyme
non-competitive
Generally-accepted model for enzyme fit
Induced fit model
Lengths of proteins
> 50 amino acids
Lengths of peptides
< 50 amino acids
Bonds that link amino acids together
peptide bonds
The only secondary amine out of the 20 amino acids
proline
the only achiral amino acid
glycine
Natural configuration of amino acids
L
pH where the amino acid exists as neutral, zwitterionic form
Isoelectric point
Separation of polar compounds based on mobility (charge and molecular mass)
electrophoresis
Convention of writing peptide sequences
N-terminus to C-terminus
Enzyme that catalyzes hydrolysis of peptide bonds
Proteases
Organic molecules/metal ions that aid enzymes in reactions
coenzymes
When the carbonyl of a monosaccharide is located at the C1 carbon
aldose
When the carbonyl of a monosaccharide is located at any carbon except C1
ketose
Carbohydrates with the OH group pointing to the right of the Fischer projection
D-carbohydrates
The simplest carbohydrate
glyceraldehyde
Process of forming an equilibrium mixture of the anomers
mutarotation
Carbohydrate with a missing hydroxyl group
Deoxy sugar
