Biochemistry |
the scientific discipline that seeks to explain life at a molecular level |
|
|
4 types of molecules |
-Nucleic Acids -Proteins -Carbs -Lipids |
|
|
Amino Acids contain |
-(COOH) carboxilic group --> -C OO- -(NH2) amino group ---> -NH3+ |
|
|
Carbohydrates contain |
(CH2O)n |
|
|
Nucleotides contain |
-Five carbon sugar(Ribose) -Nitrogen containing ring - one or more phosphate group |
|
|
Lipid solubility |
Highly insoluble because of hydrocarbon like structure |
|
|
Polymers of Amino Acids are called |
Polypeptides or proteins |
|
|
Amino Acids residues are linked by |
Peptide bonds -C-C---N-C |
|
|
Benefit of 3D shape of proteins |
- Structurally variable -functionally versatile |
|
|
Polymers of Nucleotides are called |
Polynucleotides or Nucleic acids AKA RNA or DNA -*EACH nucleic acid is made from just four different nucleotides |
|
|
Nucleotides in RNA |
-Adenine -Cytosine -Guanine -Uracil |
|
|
Nucleotides in DNA |
-Adenine -Cytosine -guanine - thymine |
|
|
Nucleotides are linked by |
PHOSPHODIESTER BONDS link the phosphate and sugar |
|
|
Function of Polysaccharides |
-performe essential cell functions by serving as fuel storage molecules and by providing structural support |
|
|
Sugar Residues are linked by |
Glycosidic Bond C-H-O-H-C |
|
|
Spontaneous Reactions |
Delta G <0 |
|
|
Exergonic reactions |
Delta G <0 spontaneous reactions |
|
|
Endergonic reactions |
Delta G > 0 non-spontaneous reactions |
|
|
For process to occur, the overall change in free E must be Negative meaning the free E of products must |
be less than the free energy of the reactants |
