Macromolecules
Large molecules made up of smaller repeated units
Monomers
Smaller units on the large molecule found in macromolecules
Polymer
Chains of monomers which form the macromolecule
Carbohydrate (CHO)
Starch, cellulose, glucose, glycogen and other sugars; composed of carbon, hydrogen, and oxygen
Lipids (CHO)
Storage for energy,
fats, oils, waxes; composed of
carbon, hydrogen, oxygen
Proteins (CHON)
controls rate of chemical reactions, regulates cell processes, Proteins and amino acids;
carbon, hydrogen, oxygen, nitrogen
Amino acids
Arranged in various orders from proteins
Nucleic Acids (CHONP)
DNA and RNA
composed of carbon, hydrogen, oxygen, nitrogen, phosphorus
DNA
Hereditary material, present in the nucleus.
(deoxyribonucleic acid)
RNA
Controls protein synthesis, present in ribosomes and nucleolus.
(Ribonucleic acid)
-ose
What do carbohydrates often end in?
-ase or -in
What do proteins often end in?
amino acids
What are the building blocks of proteins?
CHON
What elements are found in proteins?
monosaccharides or sugar
What are the building blocks of carbohydrates?
CHO
What elements are found in carbohydrates?
glycerol and fatty acids
What are the building blocks of lipids?
CHO
What elements are found in lipids?
nucleotides
What are the building blocks of nucleic acids?
CHONP
What are the elements found in nucleotides?
glucose, sucrose (table sugar), amylose (plant starch); glycogen (animal starch); celluose
What are examples of carbohydrates?
fats, oils, and waxes
What are examples of lipids?
enzymes (lipase, amylase, pepsin, trypsin), insulin (regulates blood sugar), hemoglobin (carries oxygen)
What are examples of proteins?
DNA and RNA
What are examples of nucleic acids?
carry genetic information from generation to generation; control what goes on in the cell
Why are nucleic acids important? What is their function?
enzymes run reactions in the cell; proteins transport materials like oxygen and carbon dioxide; proteins help to fight infections (antibodies)
Why are proteins important? What is their function?
energy source; in plants cellulose makes up the cell wall
Why are carbohydrates important? What is their function?
long-term energy storage; insulation, cushion organs, important in cell membranes
Why are lipids important? What is their function?
contain carbon and hydrogen
What are organic molecules?
carbohydrates
Which molecules have a 2:1 ratio of hydrogen to oxygen?carbohydrates
Organic
contains carbon and hydrogen
glucose
