Lesson 3 - Macromolecules Continued Flashcards
1
Q
Proteins
A
- Amino acids are the monomers
- Polypeptides are the polymers
2
Q
Amino Acids
A
- joined together by covalent bonds called peptide bonds formed between the carbonyl of one and the amino group of another
3
Q
Primary Structure
A
- sequence of amino acids
4
Q
Secondary Structure
A
- Foiling and coiling of polypeptide chains
- forms alpha helix and beta sheets
5
Q
Tertiary Structure
A
- additional folding due to side chains
6
Q
Quaternary
A
- two or more polypeptide chains come together forming a multilayer subchain
7
Q
Function of Proteins
A
- make cell structures required for growth and repair
- acts an enzymes in chemical reactions
- help transport molecules across cell membrane
- acts as a chemical messengers
8
Q
Dénaturation
A
- when proteins lose their structure and are unable to carry out their biological function
- caused by high temperature, radiation and pH changes
9
Q
Nucleic Acid
A
- found in DNA, RNA, ATP
- DNA and RNA are polymers
- Nucleotides are monomers
10
Q
Functions of Nucleic Acids
A
- DNA codes for genetic information
- DNA and RNA code for and make proteins
