MCAT Chem/PhysGenerally, how are proteins formed? The connecting of a string of amino acids via peptide bonds and the folding of this string to create a completed protein. The folding is determined primarily by the hydrophilic and/or hydrophobic nature of the amino acids. Stabilized by hydrogen bonds, disulfide bridges, and other intramolecular forces. Peptide (Amide) Bonds These are formed when the n-terminus of one amino acid attacks the carboxy terminus of another amino acid. Water is ...
