What are four examples of Macromolecules?
Carbohydrates, Lipids, Proteins, and Nucleic Acids
What do all macromolecules have?
Hydrogen, oxygen, and carbon
What do Proteins and Nucleic Acids both have?
What do Proteins only have?
What do nucleic acids only have?
Is a carbohydrate a polymer or monomer?
Is a lipid a polymer or monomer?
Is a protein a polymer or monomer?
Is nucleic acid a polymer or monomer?
What is the monomer of Carbohydrates?
What is the monomer of Lipids?
Lipids does not have a monomer
What is the monomer of Protein?
Amino Acids (20 different)
What is the monomer of Nucleic Acid?
Nucleotides (4 in DNA and 4 in RNA)
What is a Monomer?
A single subunit of organic molecules
What is a Polymer?
Many units/parts linked together by covalent bonds
What is dehydration synthesis?
Removal of water from organic molecules
What is a Carbohydrate?
A five-carbon ribose
What elements make up a Carbohydrate?
C, H, and O
What is the formula for Carbohydrates?
n = number of carbons
What is a Monosaccharide?
What is the formula for a Hexos sugar?
What is the formula for a Pentose sugar?
What is sugar product of DNA?
What is a Disaccharide?
Two monosaccharides covalently bonded togheter
(Mono + Mono = Disaccharide)
What is Hydrolysis?
Splitting a disaccharide into two monosaccharides by adding water
What is sucrose?
Disaccharide of the monosaccharides glucose and fructose
What is a Polysaccharide?
Many monosaccharides linked covaently
What is a starch?
Polysaccharide of glucose and stored in plants
What is glycogen?
Polysaccharide of glucose and stored in animals
What is Cellulose?
Polymer of glucose that creates plant cell walls
What is Chitin?
A polysaccharide but different because chitin has a nitrogenous group that replaces the OH group of glucose
Where is Chitin commonly found?
Exoskeleton of arthropods and cell walls of many fungi
What are two examples of Lipids?
Oil and Vingear
Is oil hydrophobic or hydrophilic?
Is vingear hydrophobic or hydrophilic?
What elements make up Lipids?
C, H, and O
What are some other characteristics of Lipids?
Less oxygen than carbohydrates, no true monomers, mix very poorly with water (hydrophobic)
What are some examples of Lipids?
Neutral Fats, Steroids, Waxes
