Biological Molecules Flashcards
3 examples of monomers
Monosaccharides
Amino acids
Nucleotides
What’s a condensation reaction
Joining of 2 molecules together with the formation of a chemical bond and involves the elimination of a molecule of water
What’s a hydrolysis reaction
Breaking of a chemical bond between 2 molecules and involves the use of a water molecule
What’s a carbohydrate
Carbohydrates are large monosaccharides made up of carbon, hydrogen and oxygen and have the general formula Cx(h2o)y
What forms when a condensation reaction occurs between 2 monosaccharides
Glycosidic bond
What’s formed by condensation of 2 monosaccharides
Disaccharides
3 common disaccharides
Sucrose
Maltose
Lactose
How is Moltose (disaccharide) formed
A condensation reaction of 2 glucose molecules
How is sucrose (disaccharide) formed
Condensation of a glucose molecule and fructose molecule
How is lactose (disaccharide) formed
Condensation of a glucose and galactose molecule
What is formed by the condensation of a-glucose
Glycogen and starch
What is formed by the condensation of b-glucose
Cellulose
The 2 groups of lipids
Triglycerides and phospholides
How are triglycerides formed
Condensation of 1 molecule of glycerol and 3 molecules of fatty acid
What are phospholipids
One of the fatty acids of a triglyceride is substituted by a phosphate- containing group
