Proteins Flashcards
1
Q
atoms commonly found
A
carbon, O2, hydrogen, nitrogen
2
Q
what are AA
A
- molecules made of atoms which are the small compoents of proteins
- there is 20 common AA
- every AA has different biochem properties
3
Q
what determines protein type
A
the structure and combination of AAs
4
Q
the 4 protein structure
A
primary, secondary, tertiary, quaternary
5
Q
Primary structure
A
sg chains of AAs (polymers) held together via peptide bonds
6
Q
secondary structure
A
protein chains containing sulphur or hydrogen resulting in either: alpha helix (sulphur) or beta pleated sheet (hydrogen)
7
Q
teritary structure
A
2 folds of polymer chains causing interactions between peptide chains and the envrioment resulting in ionic/disulphic/hydrogen bonds & hydrophobic interactions
8
Q
quaternary structure
A
4 sub-units of tertiary structures which interact with each other causing bonds to form between them
