This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Spermatozoa are incredibly unique specialized cells—once they leave the testes, they do not transcribe genes or synthesize new proteins. So, the final step in their maturation, capacitation, is regulated via posttranslational modifications (PTMs) of existing proteins. To learn more, researchers recently examined the relationship between two types of PTMs in frozen bull sperm, specifically tyrosine phosphorylation and reversible oxidative PTMs (oxPTMs). The researchers also examined the role of PRDX enzymes, as their activity is closely related to reversible oxPTMs. Proteins that bind to the egg surface, called zona-pellucida binding proteins, were especially common among reversible oxPTM modified proteins, and proteins related to the tail, or flagella, were associated with all the analyzed PTM types. Inhibiting PRDX activity during capacitation caused an increase in reversible oxPTMs and a decrease in tyrosine phosphorylation, as well as changes in the PTMs on several key proteins and enzymes..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

5.112 is an introductory chemistry course for students with an unusually strong background in chemistry. Knowledge of calculus equivalent to MIT course 18.01 is recommended. Emphasis is on basic principles of atomic and molecular electronic structure, thermodynamics, acid-base and redox equilibria, chemical kinetics, and catalysis. The course also covers applications of basic principles to problems in metal coordination chemistry, organic chemistry, and biological chemistry.

This course provides an introduction to the chemistry of biological, inorganic, and organic molecules. The emphasis is on basic principles of atomic and molecular electronic structure, thermodynamics, acid-base and redox equilibria, chemical kinetics, and catalysis.
In an effort to illuminate connections between chemistry and biology, a list of the biology-, medicine-, and MIT research-related examples used in 5.111 is provided in Biology-Related Examples.

Students learn how common pop culture references (Harry Potter books) can relate to chemistry. While making and demonstrating their own low-intensity sparklers (muggle-versions of magic wands), students learn and come to appreciate the chemistry involved (reaction rates, Gibb's free energy, process chemistry and metallurgy). The fun part is that all wands are personalized and depend on how well students conduct the lab. Students end the activity with a class duel a face-off between wands of two different chemical compositions. This lab serves as a fun, engaging review for stoichiometry, thermodynamics, redox and kinetics, as well as advanced placement course review.
