Unit 2 : Proteins Flashcards
1
Q
How are proteins formed
A
Condensation reactions of amino acids
2
Q
What functional groups do amino acids contain
A
- amino group
* carboxyl group
3
Q
How many amino acids are there
A
20
4

A
H O
| ||
N — C
5
Q
What are essential amino acids
A
Amino acids that can only be taken in through diet
6
Q
What happens when proteins are digested
A
- enzymes in our bodies break the proteins we eat down into amino acids (by hydrolysis).
- These amino acids are transported around the body by blood.
- In the bloodstream, condensation reactions build the amino acids up to produce proteins required by the body.
7
Q
What are the structure of proteins
A
Helix structure
8
Q
How do you denature proteins
A
Boiling the proteins, which destroys the active site, making the enzyme denatured
9
Q
What type of bonds do enzymes contain
A
Weak polar-polar bonds and hydrogen bonds
