Carbohydrates1: Monosaccharides and Disaccharides 1A.2 Flashcards
Macromolecules
Is a giant molecule made of many repeating units. Such molecules are called polymers and the individual unit are called monomers
Condensation
The monomers are covalently linked to make a polymer by removing water
Hydrolysis
The polymer could be broken down by the addition of water
The elements found in Carbohydrates, Lipids, Protein and Nucleic acid
-Carbohydrates: carbon, hydrogen, oxygen(CHO)
-Lipids: carbon, hydrogen, oxygen(CHO)
-Protein: carbon, hydrogen, oxygen, nitrogen(CHON)
-Nucleic acid: carbon, hydrogen, oxygen, nitrogen, phosphorus(CHONP)
Carbohydrates general formula
(CH2O)n or Cn(H2O)n
Monosaccharide example
-glucose
-fructoe
-ribose
Disaccharide example
-sucrose
-maltose
-lactose
Polysaccharide example
-starch
-cellulose
-glycogen
Monosaccharide
Simple sugar units which make up all other carbohydrates that cannot be further hydrolyzed into smaller units.
Respiration can break it down further down.
alpha-glucose
Its the primary substrate in cellular respiration and provide energy for most metabolic reaction
beta-glucose
Is a component of the cellulose microfibrils that are found in the cell of wall of palnts
Where are ribose and deoxynucleic acid is found?
Ribose is found in nucleotides that form ribonucleic acid (mRNA, tRNA,rRNA)
Deoxynucleic acid is found in the DNA
Disaccharide
Two monosaccharides can be linked by glycosidic bonds to form disaccharides
2[(CH2O)]-H2O
Condensation of Monosaccharides
Glucose+Glucose = Maltose + Water
Glucose+Fructose = Sucrose + Water
Glucose+Galactose = Lactose + Water
How is starch broken down?
By hydrolysis
