Biological Molecules Flashcards
1
Q
Monosaccharides
A
Simple sugars with 1 sugar unit
2
Q
Disaccharides
A
2 monosaccharides
3
Q
Condensation
A
2 carbs bond, forming a H2O molecule
4
Q
Hydrolysis
A
Adding H2O to break bond
5
Q
Polysaccharides
A
Monomer (single glucose units) linked by glycosidic bonds. Aka polymer
E.G. starch
6
Q
R-C=O-O-CH2 x 3
A
Triglyceride
7
Q
Saturated fats
A
No C=C
8
Q
Fatty acids + glycerol
A
= saturated fats
9
Q
H-N-H+R-C-H+C=O-O-H
A
Amino acid
10
Q
Pimary proteins
A
Linear AA sequence
11
Q
Secondary proteins
A
Secondary structure (twisted) 2 types: a-helix or b-pleated sheets
C=O–H-N bond (– = H bonds)
12
Q
Tertiary proteins
A
Folded into precise shape
Achieved by:
S-S bonds, H bonds, ionic bonds hydrophobic and hydrophilloc interactions
13
Q
Quaternary proteins
A
Different polypeptides bonded together, e.g haemaglobin
14
Q
Rf equation
A
Rf = distance moved by AA/distance moved by solvent front
