Chemistry is the branch of science that focuses on the study of matter, its composition and properties, and the reactions that occur to form new compounds. Owing to its complexity, this branch of science is subdivided into biochemistry, and organic, inorganic, analytical, and physical chemistry. The idea that matter is made up of individual and indivisible parts (atomos) originated in ancient Greece and is attributed to the polymath Democritus. This idea has continued to evolve throughout history. The discovery of the fundamental particles of an atom, namely protons, neutrons, and electrons, was a prominent landmark. Recently, the planetary model of the atom has been replaced by the atomic orbital theory, which better describes electrons and chemical bonds.

In this course, the student will be introduced to atoms and its components, characteristics of chemical bonds, stereochemistry, electronegativity, acid-base reactions, organic chemistry, and chemistry topics related to the medical field, including biochemistry and pharmacology. For optimal comprehension, the student is expected to have a high-school–level understanding of chemistry and physics.

Chemistry is a fundamental prerequisite to understanding the concepts of biochemistry, which is a basic science in medical education integrated with molecular and cell biology. Pharmacology is the branch of chemistry that utilizes the concepts of chemistry for the development of drugs with better safety profiles.

buen video introductorio
By olol . on 27. February 2024 for Overview – Introduction to Chemistry

me gusta el video por el ritmo que maneja y dar la idea que la química es importante

Excellent walkthrough of the complexities of Acid-Base calculations
By Stephen F. on 06. January 2024 for Calculation Examples – Acid-Base Reactions

These calculations were very thorough in presenting the systematic approach to breaking down Acid-Base reactions. It's almost stoichiometric, just with different underlying equations. Review questions were challenging, and the situation of having coefficients in the calculations (i.e. in the polyprotic case) we're covered explicitly

The best explanations
By Hayden . on 02. July 2023 for Atom – Introduction to Chemistry

This lecture cleared up any confusion I had about the topics covered. Everything was explained that was mentioned in the video, so one wouldn't be making any assumptions to be able to comprehend.

Great intro
By Marin W. on 26. March 2023 for Pharmacokinetics and Pharmacodynamics: Introduction

This lecture really cleared up the differences between pharmacokinetics and pharmacodynamics for me. I knew their definitions but felt like they overlapped, and putting them into stages made it make much more sense. Looking forward to the rest of the series!
