are organic compounds composed of carbon, hydrogen, and oxygen in a ratio of about one carbon atom to two hydrogen atoms to one oxygen atom
a monomer of a carbohydrate-simple sugar-contains carbon, hydrogen, and oxygen, in a ratio of 1-2-1
A double sugar formed when two monosaccharides combine in a condensation reaction
is a complex molecule composed of three or more monosaccharides
are organic compounds composed mainly of carbon, hydrogen, oxygen, and nitrogen
the linkage of monomers
when two amino acids form a convalent bond
long chains of amino acids
RNA or protein molecules that act as biological catalysts
a reactant being catalyzed
a folded enzyme; shape allows the substrate to fit into the active site
are large non-polar molecules (Don't dissolve in water)
are unbranched carbon chains that make up most lipids
have two, rather than three fatty acids attached to a molecule of glycerol
is a type of structural lipid consisting of a long fatty-acid chain joined to a long alcohol chain
molecules composed of four fused Carbon rings with various functional groups attached to them
are very large and complex organic molecules that store and transfer important information in the cell
contains information that determines the characteristics of an organism and directs its cell activities
stores and transfers information from DNA that is essential for the manufacturing of proteins
is made up of three main componets: a phosphate group, a five carbon sugar, and a ring-shaped nitrogenous base
are made up primarily of carbon atoms
clusters of atoms
carbon compounds that are built from smaller, simpler, molecules
a chemical reaction where monomers link to form polymers
a process in which complex molecules such as polymers, are broken down.
adenosine triphosphate (ATP)
a type of compound that stores a large amount of energy in their overall structure
What are the four organic compounds?
lipids, nucleic acids, carbohydrates, and proteins
thousands of glucose molecules linked together
glucose and glucose bonded together
a dissacharide, and maltose
What is glucose and frutose bonded together?
table sugar (glucose)
galactose and galactose bonded together
lactose (milk, dairy products)
What do you add to break down glucose?
water (hydrolysis reaction)
breaks down starch to get energy
What are the two purposes of a lipid?
insulation, and reserving energy
functional group in a lipid
the same molecular formula but a different structural formula (ex. gluctose, frutose)
where all carbon atoms are linked through a single bond in a lipid
where some carbon atoms are linked through double bonds
phospholipids make up
the cell membrane
phospholipids consist of
A hydrophobic end and a hydrophyllic end
examples of steroids
tesostrone, estrogen, cholestrol
What do proteins do?
build and repair tissues
What are the physical characteristics of a protein?
they are very large and consist of C, H, N, O, and sometimes S and sometimes P
How do amino acids bond?
through a condensation reaction
another name for a protein
long stretched out chains of amino acids
linked chain, then it folds onto itself
What are some characteristics of enzymes?
very large proteins, can be used over and over again, lowers activation energy, enzymes are specific,
can block substrates or active site
What differs between RNA and DNA?
DNA consists of deoxyribose and has 2 strands. RNA consists of ribose
