QUESTIONS AND CORRECT ANSWERS, LATEST UPDATE 2024
What are carbohydrates and lipids?
Organic compounds that are mostly composed of three types of atom; carbon, hydrogen and oxygen
What do carbohydrates do?
provide energy, in the form of sugars like glucose and fructose, but they also make up structures like
cellulose, which form the cell wall of plant cells
What type of carbohydrate is the most important source of energy?
mono-, di- and poly-saccharides
What are mono and disaccharides?
polar and soluble in water
What are polysaccharides?
Macromolecules resulting from polymerisation (condensation) of sugars and are not soluble in water
Examples of monosaccharides
ribose, glucose, fructose, galactose
What forms a disaccharide?
,AGRADESTUVIA
two monosaccharides linked together by condensation reactions with glycosidic bonds releasing one
H2O molecule
Examples of Polysaccharides
cellulose, glycogen and starch
Monomer of Sucrose
glucose and fructose
monomer of maltose
glucose and glucose
monomer of lactose
glucose and galactose
monomer of starch
glucose
monomer of glycogen
glucose
monomer of cellulose
, AGRADESTUVIA
glucose
In animals, what carbohydrate stores energy?
glycogen
What jobs do carbohydrates have other than storing energy?
structural components
What differs the polysaccharides all made up of glucose?
they differ in the arrangement of glucose molecules and position of the glycosidic bonds
Starch arrangement
amylopectin branched, amylose linear
What is galactose?
a sugar in milk
What is fructose?
a sugar found in fruit and honey
Main characteristic of lipids?
little to no affinity to water, mostly hydrophobic
