what is an organic compound?
PowerPoint 11 |
compound containing carbon
|
|
|
what do biological molecules consist of?
How many covalent bonds do carbon form? how many valence electrons does it have? |
consist manly of carbon bonded to carbon
carbon forms 4 covalent bonds, and have 4 valence electron |
|
|
what does functional groups mean?
|
they are small groups of atoms that have a function.
|
|
|
monomer
polymer |
monomer-is a single subunit a small molecule
Polymer -many units |
|
|
4 major classes of biological molecules
Class Monomer Polymer |
Class Monomer Polymer
nucleic acid- Nucleotide - DNA,RNA protein ---- Amino Acid---polypepide Carb-monosaccharide,polysaccharid Lipid(fat)--fatty acid- triglyceride |
|
|
what is the carbohydrate form in DNA and in RNA?
|
carbohydrate is Deoxyribse in DNA, and Ribose in RNA
|
|
|
Nitrogenous bases include
Purines and Pyrimidines AG-TC and U which are purines? which are pyrimidines? |
purines are adenine (A) and guanine (G)
pyrimidines are thymine( T) and cytosine(C) and uracil (U) |
|
|
what is A-T; G-C
|
the polynucleotides of DNA that are complementary; genetic information is carried in the sequence of nucleotides.
|
|
|
in DNA and RNA which contains Ribose, which contains deoxyribose?
|
DNA contains Doxyribose RNA contains Ribose
|
|
|
what are the FUNCTIONAL differences of DNA and RNA?
|
genetic infromation is STORED in DNA, and RNA is used to get that information
|
|
|
other nucleotides that play a critical role in energy transfer in cells
|
ATP Adenosine triphosphate
Primary energy currency of the cell |
|
|
Proteins Functions
try and list 7 |
enzyme catalysts
defense transport support motion regulation storage |
|
|
Proteins are POLYMERS of AMINO ACIDS
what is a polypeptide? |
a Polypeptide is- another word for protein-
a string of amino acids connected by peptide bonds, a peptide bonds is a covalent bond formed between adjacent amino acids |
|
|
in Proteins the structure of the R group does what?
|
the R is the variable group and it dictates the chemical properties of the amino acid
|
|
|
can amino acids be classifyed as;
nonpolar polar charged aromatic special function |
yes

|
|
what is
1 glycerol 2 fatty acids (nonpolar) a phosphate group(polar) |
Phospholipid
phosholipids contain polar heads and nonpolar tails |
|
|
a functional group consisting of a hydrogen atom joined to an oxygen atom by a polar covalent bond. Molecules in this group are called alcohols
What is this group called? |
Hydroxyl group
