Chapter 3 : The Molecules Of Cells Flashcards
Proteins may consist of what?
Thousands of convalently connect atoms
4 main classes of large biological molecules
- carbohydrates
- lipids
- proteins
- nucleic acids
Units that serve as the building blocks of polymers
Monomers
What is a polymers?
A molecule consisting of many identical or similar molecular units string together - much like a train consists of many individual cars
How many amino acids do proteins have?
20
Dehydration reaction
A reaction that removes a molecule of water
Hydrolysis
Breaking with water and cells break binds between monomers by adding water to them
What are the largest lipids and how are they formed?
The fats; they’re formed by dehydration reactions from several smaller molecules
Lipids are generally smaller than what?
Polysaccharides, proteins, nucleic acids
What are polymers assembled by dehydration reactions from their respective monomers
Polysaccharides, proteins, nucleic acids
What is maltose also called?
Malt sugar
What’s polysaccharides?
Polymers of monosaccharides linked together by dehydration reactions
Glycogen
Animals store excess sugar in the form of another glucose polysaccharide
What is cellulose?
The most abundant organic compound on earth
What are lipids?
They’re diverse compounds that consist mainly off carbon and hydrogen atoms linked by no plat covalent a bonds.
