As a paramedic student, I love that you relate dehydration synthesis and hydrolysis to their relevant physiological utility. Thank you for this video!

You solved the question at 23:47 incorrectly the correct answer should be D. Also, a small correction: you listed “Extracellular matrix -glycogen”, but glycogen is not part of the extracellular matrix; it is an intracellular storage polysaccharide.

On the question 6:50, why does it affect the third protein structure and not the second one?

It is a good simplified presentation for beginners. However, there are some mistakes or typos one of them is in sickle cell conditions glutamic acid is substituted or replaced by valine at position six (6) of the beta chain, not at position seven (7). Overall, I liked it.

Why skip Chapter 2, Atoms and Molecules, the most important foundation in biology and any science, because biology is a course that borrows chemistry and mathematics.
