WebClassification of Proteins. Based on the molecular shape, proteins can be classified into two types. 1. Fibrous Proteins: When the polypeptide chains run parallel and are held together by hydrogen and disulfide bonds, then the fiber-like structure is formed. Such proteins are generally insoluble in water. WebThe properties of the folded state of a protein, a compact, highly hydrogen bonded structure with a non-polar core, can be understood by considering the energetic terms that lead to the stability of the folded state. Proteins form a stable folded state if the standard energy difference, ΔG ∘ = G ∘ U − G ∘ N.
