The Two Types of Fiber Fiber is classified by its affinity for water 1. Soluble fiber: dissolves in water and is fermented by intestinal bacteria Many are viscous, have thickening properties Move more slowly through GI tract Examples: Pectin in fruits and vegetables, beta-glucan in oats and barley, gums in legumes, psyllium 2.
Oleic acid is a fatty acid that occurs naturally in various animal and vegetable fats and oils. It is an odorless, colorless oil, although commercial samples may be yellowish. Oleic acid as its sodium salt is a major component of soap as an emulsifying agent.
Sulfuric acid in its pure form is a colorless viscous liquid commonly called oil of vitriol. The chemical formula for sulfuric acid is H 2 SO 4 and it is commercially available as a 96-98% solution or 18M H 2 SO 4. Concentrated sulfuric acid is covalent in nature as the acid is unionized. The atoms in the molecule are covalently bonded to one another. In this form sulfuric acid can be transported in stainless steel tankers. If concentrated sulfuric acid is added to water the reaction is extremely exothermic due to formation of hydrogen ions.
