amino group - Consists of hydorgen and nitrogen atoms (-NH3+) carboxyl group - A -COOH group, found in organic acids. R group - a functional group that defines a particular amino acid that makes it a specific protein (20 amino acids) aka side chain alpha carbon - the central carbon atom of each amino acid amino acid backbone - The structure comprised of the amino group, carboxyl group with a central alpha carbon atom. Hydrophobic - non polar, afraid of water polar - Amino acid Molecule with partial charges. Mixes with water. charged - Amino acid has a positive or negative charge Polypeptide - A single protein chain formed by amino acids bonded together peptide bond - The chemical bond that forms between the carboxyl group of one amino acid and the amino group of another amino acid by dehydration ( In which a water molecule is removed, C-N bond) Hydrolysis - Peptide bonds can be broken by this...A chemical process that splits a molecule by adding water. ( this happened frequently in the stomach when proteins begin to bee digested into their amino acids)
