The basic conception of a subject now known as Subatomic Particle physics dates back to 500 BC when the Greek philosopher Leucippus and his pupil Democritus suggested that matter consists of small, indivisible particles, which they called atoms
We now know that atoms are not indivisible , since they contain protons, neutrons, electrons and other subatomic particles. However, other than this mistake Dalton's ideas are essentially correct in his Atomic Theory.
Matter is anything that has mass and takes up space. Matter has different states and their discovery and characterization employed the scientific method.
Significant Figures or Digits are the amount of digits that are accurate in a calculation. This is determined by how many digits there are in the numbers of the calculation.
Rising from the ashes...not to be defeated! Students, check out my introduction to chemistry for the student in the process technology department. I hope this will be helpful!Introductory General Chemistry
Marion Carroll | Homework ParadiseSince leaving the classroom I have been longing to help students academically with their questions and concerns in basic chemistry. biology and biochemistry. Homework Paradise might be a way to do that. Give
That's right. All done for another summer of kicking back, relaxin', readin', writing and some overall reflectin'. Things are looking up since the last time summer came around. Hope you enjoy yours in spite the challenges. God will bless in
I welcome your comments here after or before your class. Suggestions for topics and clarification may be and are encouraged to be posted here. You can be anonymous or you may identify yourself. I especially would like to see comment strings,
Chapter 1 contains a discussion of thermodynamics. Your comments are always welcomed. Enthalpy, entropy and free energy changes lie underneath all biochemical reactions driving them to completion and initiating the next reaction. Carefully re
Here is a summary of some important details concerning amino acid structure and properties. You should also be able to download theses videos for free from the iTunes music store if you have an account. You will find it in the Podcast section
After discussing amino acids, protein primary, secondary and tertiary structure, we will discuss protein structure and function using hemoglobin: the classical allosteric protein.
Here is the first of 2 installments on our Enzyme Kinetics lectures. Use this for a quick review of the terms KM, VMAX, Kcat, KS and enzyme efficiency. More description of the Linweaver-Burke and inhibition will follow in the 2nd installment.
