Document Summary
Is the simple amino acid sequence of about 50 to 300: secondary. Is obtained as the amino acid sequence folds in to a 3d structure due to a repeated pattern of hydrogen bonds between nh and co components of aa: tertiary. Is obtained as the r-side chain groups of aa participate in bonding with one another: quaternary. Necessary for a functional protein that requires more than one polypeptide: primary structure: amino acids are linked by peptide bonds to form polypeptide chains. This is simply linear polymers formed by linking the - carboxyl group to the -amino group of another amino acid. The formation of the peptide bond is associated with a loss of water. This reaction stays on the side of hydrolysis than synthesis because the rate is pretty low. Know the condensation reaction a series of aa joined together is called a polypeptide chain and each amino acid unit is a residue.
