Ex. 29 Flashcards
Macromolecule
Polymer
Large structure made of smaller structures
Carbohydrates, Nucleic acids, Proteins, and Lipids
Micromolecule
Monomer
Small structure that makes up larger structures
Dehydration
Process of removing water to build macromolecules
Hydrolysis
Process of adding water to break down macromolecules into micromolecules
Carbohydrates
Rich in sugar and starches
Can be broken down into simpler molecules that provide energy
Made of Saccharide
Saccharide
Sugar
Makes up Carbohydrates
Monosaccharide
carb made of 1 sugar molecule
ex. Glucose
Sucrose
carb made from 1 molecule of glucose and 1 molecule of fructose
ex. Table sugar
Oligosaccharide
Carbs with intermediate length anywhere between 3 to 100 monosaccharides
Polysaccharide
Huge carb made of hundreds of monosaccharides
ex. Cellulose in plants
Proteins
Essential to the structures and activities of life
Function as: energy source, fight infection, assist in O2 transportation
Macromoluecule made up of micromolecules called amino acids
Peptide bonds
2 or more amino acids bonded together
Dipeptide bond
2 amino acids bonded together
Polypeptide chain
2 or more amino acids bonded together
Protein shapes
Primary - Chain
Secondary - Folded/Pleated
Tertiary - 3D
Quaternary - Clustered
Nucleic Acids
Make up an organism’s genetic information
DNA/RNA
Made up of the micromolecule nucleotide
Nucleotide
Makes up DNA/RNA
Made of 3 components
- Sugar
- A phosphate group
- A nitrogen base
DNA Nitrogen bases
- Adenine
- Thymine
- Guanine
- Cytosine
G pairs with C
A pairs with T
RNA Nitrogen bases
- Adenine
- Guanine
- Cytosine
- Uracil
G pairs with C
A pairs with U
Lipids
used for energy storage and make up our cell membranes
2 classes: simple and compound
Simple lipids
Contains only Carbons, Hydrogens, and Oxygen
Includes fats and steroids
Can be grouped as Monoglycerides, Diglycerides, and Triglycerides
Saturated or unsaturated
Saturated Lipids
No double bonds
Solid
Unsaturated Lipids
1 or more double bonds
Oils
Compound lipids
Contains Carbons, Hydrogens, Oxygen, fatty acids, and glycerol
DNA
Two strands
During replication, the two strands untwist, pull apart, and the old strand becomes part of the new strand
RNA
Singel stranded
