14 year old interested in pursuing chemistry, need sources to learn

Would you guys know any site, documentary series/youtube videos, or books that could teach me on chemistry, or what I will be taught in the future if I intend to take it through all of high school/post-secondary? I'm quite fascinated by the structure of matter and the way you could change it into something completely different.

Also, I understand chemistry is a broad term, if I could narrow it down a little, I'm into biological chemistry, and things relevant to it.

I appreciate it.
