Proteins Flashcards
(23 cards)
Proteins are large biological molecules that perform _
Thousands of metabolic roles
Each protein function is defined by its _
Shape
Shape of protein is based on an _
Exact chemical make up
A protein is a polymer _
Long molecule made up of smaller units
Amino acids are simple organic compounds that include _
A nitrogen atom
Human proteins built using _ amino acids
20
There are a few more _ used in other life forms
Amino acids
Every protein has a precise order of _
Amino acids chained together
A typical protein includes about _ amino acid molecules
500
Recent advances in computing mean we can predict the shape of a protein from its _
Primary structure
Predicting shape of protein from primary structure means we can _
Figure out what a protein does and adjust its design
There a four levels to a protein’s _
Ultimate form
Four levels to ultimate form because the many components of a long protein molecule _
Attract and repel other parts of the chain
By attracting and repelling other parts of the chain, protein folds into _
A complex three-dimensional shape
A prion is a _ that can trigger disease
Misfolded protein
Prions trigger disease by making other
Variants of the same protein
The other variants of the prions also _
Change their shape
_ are very rare
Prion diseases
Tiny body of a fruit fly includes about _ types of proteins
10k
Proteins also work at molecular level as _
Enzymes
Precise shape of proteins means they can be _
Put to use in highly specific ways
If primary structure is correct, then any _ will also be correct
Quaternary shape
With primary and quaternary shape correct, it is possible to _
Manufacture proteins in large quantities
