Document Summary

Amino acids are the monomers that make up all proteins (polymers) carbon: called this because the amino group is attached to the - Hydrogen atom and a side chain ( r group) are attached to the. Within the body (physiological ph) the carboxylic group will be. Carbon of every amino acid deprotonated and the amino group will be protonated the amino acid: this is the zwitterion form pka of the carboxylic group and amino group are about ~2 and 10 respectively. Glycine, alanine, valine, leucine, and isoleucine aliphatic side chains. R groups are more extended and more hydrophobic. More hydrophobic amino acids, such as isoleucine, are more frequently found within the core of a folded proteins molecule, where they are shielded from water. Glycine frequently found on the surfaces of proteins due to its inability to form tight turns in protein structures.
