Macromolecules Flashcards
1
Q
Macromolecules
A
- large biological molecules divided into four categories
2
Q
What are the four types of macromolecules?
A
- Proteins
- Lipids (fats)
- Carbohydrates
- Nucleic Acids
3
Q
Polymer
A
- a large molecule compromised of smaller monomers
4
Q
Monomer
A
- a smaller part of a large molecule (polymer); subunit
5
Q
Carbohydrates
A
- molecules made of carbon, hydrogen, & oxygen atoms in a 1:2:1 ratio; includes starches & sugars
6
Q
Lipids
A
- molecules made of carbon, hydrogen, & oxygen atoms; made of monomers called fatty acids; includes waxes, oils, & cholesterol
7
Q
Fatty Acids
A
- chains of carbon atoms bonded to hydrogen atoms (found in lipids)
8
Q
Proteins
A
- molecules comprised of carbon, hydrogen, oxygen, & nitrogen; made of monomers called amino acids
9
Q
Amino Acids
A
- molecules that contain carbon, hydrogen, oxygen, nitrogen & sometimes sulfur; 20 different kinds
10
Q
Nucleic Acids
A
- molecules that contain carbon, hydrogen, oxygen, nitrogen, & phosphorus; 2 types are DNA & RNA; have only 1 function
11
Q
nucleotide
A
- the monomer of a nucleic acid
12
Q
What are the 3 parts of a nucleotide?
A
- a sugar
- a phosphate group
- a nitrogenous base
13
Q
Peptide Bond
A
- the bond that holds amino acids together
