What is Biochemistry?
![Page 4: Introduction to Biochemistry - MIT ESP - HomeIntroduction to Biochemistry Miguel Aguilar. About me • Originally from El Salvador. • Rising junior studying Chemistry and Biology](https://reader035.vdocuments.us/reader035/viewer/2022062302/5ed3b6c0c1bc7732fe50c4b1/html5/thumbnails/4.jpg)
What is Biochemistry?
The study of cellular processes and life at the molecular level.

Why Biochemistry?
![Page 6: Introduction to Biochemistry - MIT ESP - HomeIntroduction to Biochemistry Miguel Aguilar. About me • Originally from El Salvador. • Rising junior studying Chemistry and Biology](https://reader035.vdocuments.us/reader035/viewer/2022062302/5ed3b6c0c1bc7732fe50c4b1/html5/thumbnails/6.jpg)
Why Biochemistry?
• Life must be studied at a molecular level to truly understand it.
• Molecular features help to explain mechanisms of human disease and therapeutics.
• Experimental design is critical for outcome

What’s inside a cell?
Water!
![Page 11: Introduction to Biochemistry - MIT ESP - HomeIntroduction to Biochemistry Miguel Aguilar. About me • Originally from El Salvador. • Rising junior studying Chemistry and Biology](https://reader035.vdocuments.us/reader035/viewer/2022062302/5ed3b6c0c1bc7732fe50c4b1/html5/thumbnails/11.jpg)
Water in a biological context.• The human body is 70% water by weight.• Chemical reactions in biological processes evolved in water.• Water does not tend to autoionize, but its ionization products
play an important role in influencing biomolecules.• Water its required to transport substances all across the body.
![Page 12: Introduction to Biochemistry - MIT ESP - HomeIntroduction to Biochemistry Miguel Aguilar. About me • Originally from El Salvador. • Rising junior studying Chemistry and Biology](https://reader035.vdocuments.us/reader035/viewer/2022062302/5ed3b6c0c1bc7732fe50c4b1/html5/thumbnails/12.jpg)
Water in a physical context. • Water has strong interactions with itself, resulting in its
particular solvent properties.• Water is the most abundant substance on Earth.• Water’s solid form is less dense than its liquid form at normal
conditions.• Water resists changes of state, thus moderating Earth’s
temperature.

Gases in Water

Oxygen
• Required for aerobic respiration as the final electron acceptor.• Used to break down food in order to produce energy.• Normally carried around the body as hemoglobin-O2.• However, uncarried oxygen in our body can be quite dangerous
as it is highly reactive and can result in tissue damage
