What is the function of carbohydrates?
To give quick energy
Monosaccharides contain how many carbon atoms?
Between 3 and 7 carbon atoms
Glucose has how many carbon atoms?
Disaccharides contain what?
What is maltose?
It is formed from 2 glucose molecules
What is sucrose?
(table sugar) that is formed from glucose and fructrose
Complex carbs that require more energy for the body to break the bonds between them.
The storage of glucose in humans
Where is glycogen stored?
In the liver
In what species is starch found in?
What is cellulose known as?
Fiber or roughage
Why can't humans digest cellulose?
Because humans do not have the proper digestive enzymes
What are lipids?
Fatty acids & glycerol
What are the functions of lipids
To store energy and insulate around the organs
What is one of the unique characteristics about lipids?
They are nonpolar which causes them to be hydrophobic (water-fearing)
What are the differences between unsaturated fats and sturated fats?
Unsaturated fats are liquid at room temperature.
Saturated fats are solid and stored at room temperature.
What type of fatty acid does not have hydrogens bonded to every possible bonding site?
What types of fatty acids have the maximum number of hydrogens boned to the molecule?
What types of lipids contain a polar 'head' and a non polar 'tail'?
What are steriods?
Lipids that have a backbone of four carbon rings.
Cholesterol is a type of what?
Proteins are composed of what?
What are the functions of proteins?
some serve as structual proteins and others as functional proteins
Role of proteins in the body?
- structual proteins such as nails and hair
- transport proteins such as hemoglobin and red blood cells
- form part of plasma membranes
Uniqe characterisitics of proteins?
amino acids are joined with peptide bonds
What is a dipetide?
When two amino acids join together
What is polypeptide?
When three or more amino acids join together
The structures of proteins?
What is a primary structure?
What is a secondary structure?
What is a teritary structure?
What is a quarternary structure?
2 or more linked polypeptides
What is metabolism?
The sum of all chemical reactions that occur in the body
What are enzymes?
substances that help speed up a reaction, but are not used up by the reaction.
Enzymes are specific to a particular what?
Substrate, they only work with substances that they have a particular fit with.
What do enzyme end with?
Substrates normally end with?
What is the active site?
The location in which the enzyme and the substrate fit together
Enzymes _______ the activiation energy of a chemical reaction
What are the factors that influence enzyme activity?
- pH (acid)
- Temperature (heat)
- concentration of reactants and products
Nucleic Acids are composed of what?
What are the functions of nucleitides?
Store genetic information, make proteins, and serve as an energy molecule
What do nucleotides contain?
- some type of phopshate group
- some type of sugar molecule
- some type of nitrogenous base
What are the three types of nucleic acids?
What is DNA?
The way genetic information is stored in the body
What does DNA contain?
- 5 carbon sugars=deoxyribose
- nitrogen base (adeninie, guanine, cytosine, and thymine)
RNA contains what?
- 5 carbon sugars = ribose
- nitrogen base (adennine, guanine, cytosine, and uracil)
ATP is used as?
An energy molecule that is spent in the body when work needs to be performed.
ATP contains what?
- 3 phosphate groups
- 5 carbon sugar= ribose
- nitrogen base (adenosine)
