Proteins
What are the variable groups in amino acids? How many types are there.
R, 20
What are the functions of nucleic acids?
Carry genetic information.
What are the components of a triglyceride?
Glycerol, 3 fatty acids
S
Synthesis
What elements are found in proteins?
CHNOPS
What is primary structure?
Amino acid sequence
What are the bonding patterns between nitrogen bases?
A--T, C--G
A--U
What is the general polarity of most lipids?
Non-polar
T
transport
Which elements are found in nucleic acids?
CHNOP
List two types of interactions observed in tertiary structure.
Hydrophobic, ionic bonds, hydrogen bonds, disulfide bridges.
What is the big difference between the structure of DNA and RNA?
DNA- double stranded, double helix
RNA- single helix
What is the combination of elements present in ALL lipids?
CHO, no specific ratio
E
Excretion
What is the middle step of an enzymatic reaction called?
Enzyme-substrate complex
Define denaturing and what factors will cause it to occur?
Protein structure ruined by environmental factors. pH, temperature, salinity.
What does Pure as Gold mean?
Purines= adenine and guanine
What are the three functions of lipids?
1. Long term energy storage
2. Insulation
3. Hormones/ steroids
N and G
Nutrition, Growth and Development
What are the two types of enzyme reactions?
Synthesis and decompostion
Describe how a protein's structure relates to its function.
Amino acid chain dictates secondary folding. Interactions between R groups in helices and sheets arrange themselves in tertiary. The way a protein is shaped indicates what its function will be.
What are the parts of a nucleotide? Which part does hydrogen bonding? Which pieces make up the backbone of the polymer?
Phosphate, sugar, nitrogen base. Base, sugar-phosphate.
What distinguishes a saturated from unsaturated fatty acid?
Fluidity, double bond= unsaturated
R, R, R
Respiration, Reproduction, Regulation
Buffer absorbs excess OH- or H+ so the solution does not change pH.
