Essential element in all biomolecules. Can form 4 bonds.
What is carbon?
Long chains of simple sugars (monosaccharides) linked together
What is a Polysaccharide?
Chain of amino acids; combines to form ______
What are polypeptides (proteins)?
This nitrogenous base is not found in DNA but is found in RNA
What is uracil?
Type of bond that is responsible for water's unique properties, including cohesion, adhesion, surface tension and high specific heat.
What is hydrogen bond?
Carbohydrates, proteins, lipids, and Nucleic acids
What are categories of macromolecules in living things
Made up of glycerol(3 carbon molecule) and 3 fatty acids(long hydrocarbon chain)
What is a Lipid?
Breaking down of proteins due to unfavorable pH, temp, etc. The protein doesn't function properly anymore.
What is denaturation?
Biuret Solution turns ________if _______ are present.
What is purple and proteins?
Type of covalent bond that is formed when amino acids combine
What is peptide bond?
Organic compound made up of sugar molecules that contain the elements C, H, O in a 1:2:1 ratio.
What are carbohydrates?
Type of fat - solid at a room temperature. ex. butter; fatty acid chains have single bonds
What are saturated fats?
Proteins and nucleic acids have this specific element
What is nitrogen?
This indicator turns blue-black if starches are present.
What is Iodine/Lugol's Solution?
Type of bond between H and O within a water molecule. This bond contributes to water's polarity.
What is polar covalent bond.
Process by which biomolecules combine, water is produced.
What is dehydration synthesis?
This indicator turns orange/red if sugars are present.
What is Benedict's Solution?
This biomolecule contains phosphorous
What are nucleic acids?
One way you can test for lipids
What is place a sample on a brown paper bag?
This indicator is uses a water bath for its test.
What is the Benedict's Test?
Process by which biomolecules are broken down. Water is a reactant.
What is hydrolysis?
Monomers of proteins, building blocks of protein, there are 20 different of these
What are amino acids?
Both DNA and RNA have these three components
What is - sugar, phosphate group and nitrogenous base?
The difference between an enzyme and a substrate
What is the substrate is the molecule being acted upon and the enzyme is the specific catalyst attached to the substrate?
What is shape, pH, Temperature
