monomers and polymers / carbohydrates Flashcards
what are polymers?
large complex molecules composed of long chains of monomers joined together
what are monomers?
small, basic, repeating molecular units
what are examples of monomers?
● monosaccharides
● amino acids
● nucleotides
describe carbohydrates
● contain carbon, hydrogen and oxygen
● polymers
● source of energy for organisms
● made from monosaccharides
what are 3 types of carbohydrates?
● monosaccharides
● disaccharides
● polysaccharides
what are examples of monosaccharides?
● glucose
● fructose
● galactose
draw an alpha and beta glucose
.
what type of sugar are monosaccharides?
all hexose sugars
what is the formula for monosaccharides?
C6H12O6
what do different monosaccharides contain different number of?
carbon atoms
what is a hexose sugar?
a monosaccharide with six carbon atoms in each molecule
what are the types of glucose?
● alpha - hydrogen above hydroxyl group
● beta - hydrogen below hydroxyl group
● isomers
what are isomers?
same molecular formula but atoms connected in a different way
what reaction joins monosaccharides together?
condensation reaction
what is a condensation reaction?
● when 2 molecules join together with formation of a new chemical bond
● a water molecule is released when bond is formed
what forms between the 2 monosaccharides as a molecule of water is released?
glycosidic bond
