Alright so the last couple videos I watched dealt with proteins. I did not realize until now how much proteins really do for the body. Apparently they do everything; they make up the structures of the cell, the enzymes. They also function in defense and the movement of the cells along with other things. Thought the one thing they are not involved in is hereditary information. They are very complex though, made of groups of amino acids usually called peptides. The chemical structure involves an alpha Carbon surrounded by four different functional groups. Three of these groups stay the same for each amino acid.  The fourth group is usually labeled R, called the side chain, and can be polar, non-polar, or charged. I think it is all pretty interesting. Gives a person a bit of perspective on the human body. I mean there is so much complexity.  I mean the second video I watched was thirty minutes long talking about the different forms of the amino acids, specifically the R chain. There are so many different varieties. I have a handout that only talks about twenty of them. Each variety have a different function. Each peptide has at least three amino acids, meaning 20^3 combinations.

Either way this is so fascinating. I mean I enjoy learning about it a lot. I just do not think it all sinks in. There is so much vocabulary. Anyway, I am glad that it fascinates me. That means that I am willing to watch all the videos through and through.
