Term
Organic Compounds, what are they? How are all similar
Definition
all have a similar 'skeleton' made up of at least carbon, hydrogen, and oxygen
Term
what is common about the structure of organic compounds
Definition
made up or carbon chains. subunits called monomers combine to form polymers/macromolecules
Term
what are the four types of organic compounds?
Definition
lipids, protiens, carbohydrates, and nucleic acids
Term
~*CARBOHYDRATES*~

what are the elements in carbs?
Definition
ratio of 2 hydrogen and 1 oxygen for every 1 carbon atom
Term
what are the subunits of carbs?
Definition
smallest is monosaccharide, which combine to form disaccharide, which combine to form polysaccharide.
Term
name 3 monosaccharides of carbs
Definition
glucose, fructose, and galactose. C6H12O6
Term
name three disaccharides of carbs and their compositions
Definition
1.) Sucrose (table sugar)- glucose and fructose* 2.) Lactose (milk sugar)- glucose and galactose* 3.) Maltose (grain sugar)- glucose and glucose*

C12H22O11
Term
name four polysaccharides of carbohydrates and their function
Definition
1.) starch- food storage for glucose in plants* 2.) glycogen- food storage for glucose in animals (higher form of starch)* 3.) cellulose- forms cell walls of plants, structural suppose* 4.) chitin- component of exoskeleton of anthropods
Term
what is the ratio of elements in a barbohydrate
Definition
2 hydrogen and one oxygen for every one carbon atom
Term
~*LIPIDS*~ what is the subnit of lipids
Definition
glycerol, technically
Term
what is the concentration of elements in lipids?
Definition
carbon, hydrogen, barely any oxygen
Term
what do the terms 'saturated' and 'unsaturated' fats mean?
Definition
the concentraion of hydrogen in them. saturated fats have single carbon bonds, solid at room temp. unsaturated fats have double carbon bonds and are liquid at room temperature
Term
how many calories are in one gram of fat?
Definition
9
Term
name two functions of lipids
Definition
long-term energy storage * inculation and protective coatings for cells
Term
why are lipids insoluable in water?
Definition
they are non-polar molecules
Term
what are triglycerides?
Definition
lipids made up of 3 fatty acid chains
Term
~*PROTEINS*~ what are protiens made of?
Definition
CHONS- carbon, hydrogen, oxygen, nitrogen, and sulfur
Term
the key phrase to remember about proteins is...
Definition
structure and function- they're the building blocks of the structure of organism components.
Term
what are the subunits of proteins? name some characteristics
Definition
amino acids- each contain a central carbon atom * 20 of them * form peptide bonds * covalently bonded to each other to form a polypeptide * consist of carboxyl groups
Term
what does the word globular refer to?
Definition
many polypeptides
Term
name four examples of proteins and their functions
Definition
1.) hemoglobin- regulates oxygen in red blood cells* 2.) collogen- goes in skin* 3.) actin and myosin- help contract muscle* 4.) enzymes- speed up chemical reactions, help digest food and store and release energy
Term
what can cause a protein to be unfunctional?
Definition
bieng denatured by extreme heat, acidity, etc.
Term
~*NUCLEIC ACIDS*~ what are nucleic acids composed of
Definition
CHONP- carbon, hydrogen, oxygen, nitrogen, phosphorus
Term
what is the subunit of a nucleic acid?
Definition
nucleotide- which consists of a sugar, a phosphate, and a base
Term
what are the two examples of nucleic acids?
Definition
DNA and RNA
Term
what does DNA do?
Definition
makes up genes and hereditary material. instructions for protein synthesis
Term
what does RNA do?
Definition
involved in protein synthesis, when the body makes proteins
Term
the cell's activities are controlled by _____________
Definition
nucleic acids
Term
~*GENERAL*~ what is an isomer?
Definition
same molecular formula, but different structure
Term
what is a condensation reaction? AKA dehydration synthesis
Definition
occurs when monosaccharides COME TOGETHER and lose a molecule of water. DEHYDRATION=COMING TOGETHER
Term
what is hydrolosis?
Definition
occurs when two monosaccharides break apart, and gain a molecule of water
Term
true/false.... carbon atoms can bond together in straight chains, branched chains, or rings
Definition
true
Term
true/false..... large molecules containing carbon atoms are called micromolecules
Definition
false
Term
true/false....... proteins are complex polymers
Definition
true
Term
what is an example of dehydration synthesis/condensation reaction?
Definition
process in cells
Term
what is an example of dehydration synthesis/condensation reaction?
Definition
process in cells
Term
what is an example of hydrolosis?
Definition
digestion, food breaks apart
Term
what is the main function of all organic compounds?
Definition
to build and mantain cell parts
