a) Proteins and Peptides
i) Myoglobin and hemoglobin are examples of class of cmpds known as proteins, linear
polymers of btw 40-10,000+ amino acids. Avg molecular weight of an amino acid is
~110 amu, so a modestly sized protein w/ ~300 amino
HyperPhysics - Laws of Thermodynamics
First Law of Thermodynamics
i. First law of thermodynamics is application of conversion of energy principle
to heat and thermodynamic process:
ii. Change in internal energy of a system is equal to heat added to sys
Phosphatidate (glycerol 3-phosphate with two fatty acids on the 1 and 2 carbons) is a central
intermediate in lipid metabolism (Figure 29.1).
The fatty acid on the 1 carbon is usually saturated while the fatty acid on the 2 carbon is usually
In 1940s, Avery, MacLeod, & McCarty conducted series of experiments showed DNA was
transforming factor of Griffiths experiments w/ Streptococcus pneumoniae & mice.
In 1953, Watson & Crick published paper describing sxr of DNA (Fig33.1) & they
