Macromolecules Flashcards
Macromolecules
Polymers made of repeating monomers
What are the four major macromolecules?
Carbohydrates, lipids, proteins, and nucleic acid.
Carbohydrates monomer
Sugars or monosaccharides
Lipids monomer
Fatty acids and glycerol
Proteins monomer
Amino acids
Nucleic acid monomer
Nucleotides
What is carbohydrates polymer?
Polysaccharides
Example: glucose, sucrose, photos, starch, cellulose.
Lipid polymer
Triglyceride
Nucleic acids parts
1.) 5 – carbon sugar.
2.) phosphate group
3.) nitrogenous base
What do carbohydrates do?
They are the main source of energy for living things; quick energy and use for structural purposes
What do lipids do?
Long-term energy storage, they build biological membranes and waterproof coverings
What do proteins do?
They control Rita cell processes that form important tell your structures, and they transport substances in and out of the cell.
What do nucleic acids do?
They store and transmit, hereditary or genetic information
What is a saturated fat?
Lack double bonds between carbon atoms
What is unsaturated fat?
There’s at least one double bond in the fatty acid chain of carbon
