Value-added uses for crude glycerol--a byproduct of biodiesel production.
Summary of "Value-added uses for crude glycerol--a byproduct of biodiesel production."
ABSTRACT:
Biodiesel is a promising alternative, and renewable, fuel. As its production increases, so does production of the principle co-product, crude glycerol. The effective utilization of crude glycerol will contribute to the viability of biodiesel. In this review, composition and quality factors of crude glycerol are discussed. The value-added utilization opportunities of crude glycerol are reviewed. The majority of crude glycerol is used as feedstock for production of other value-added chemicals, followed by animal feeds.

Medical and Biotech [MESH] Definitions
Glycerol Kinase
An enzyme that catalyzes the formation of glycerol 3-phosphate from ATP and glycerol. Dihydroxyacetone and L-glyceraldehyde can also act as acceptors; UTP and, in the case of the yeast enzyme, ITP and GTP can act as donors. It provides a way for glycerol derived from fats or glycerides to enter the glycolytic pathway. EC 2.7.1.30.
Food Inspection
Examination of foods to assure wholesome and clean products free from unsafe microbes or chemical contamination, natural or added deleterious substances, and decomposition during production, processing, packaging, etc.
Glycerol-3-phosphate Dehydrogenase (nad+)
An NAD-dependent enzyme that catalyzes the oxidation of sn-glycerol 3-phosphate to glycerone phosphate.
Glyceryl Ethers
Compounds in which one or more of the three hydroxyl groups of glycerol are in ethereal linkage with a saturated or unsaturated aliphatic alcohol; one or two of the hydroxyl groups of glycerol may be esterified. These compounds have been found in various animal tissue.
Glycerol-3-phosphate O-acyltransferase
An enzyme that transfers acyl groups from acyl-CoA to glycerol-3-phosphate to form monoglyceride phosphates. It acts only with CoA derivatives of fatty acids of chain length above C-10. Also forms diglyceride phosphates. EC 2.3.1.15.
