fat is a fatty acid that consists of triglycerides containing only saturated fatty acids. Saturated fatty acids have no double bonds between the individual carbon atoms of the fatty acid chain. That is‚ the chain of carbon atoms is fully saturated with hydrogen atoms. There are many kinds of naturally occurring saturated fatty acids‚ which differ mainly in number of carbon atoms‚ from 3 carbons (propionic acid) to 36 (hexatriacontanoic acid). Unsaturated fat‚ however‚ is a fatty acid in which

The accumulation of hydroperoxides is commonly monitored using the measurement of peroxide value (PV). The PV‚ along with acid

BRONSTED-LOWRY ACIDS AND BASES 1. The Bronsted-Lowry definition There are many definitions of acids and bases in existence‚ but the most useful one is the Bronsted-Lowry definition: An acid is a substance which can behave as a proton (re presented as a hydrogen ion‚ H+) donor. Any substance which contains hydrogen bonded to a more electronegative element can thus behave as an acid: HCl == H+ + Cl- H2SO4 == H+ + HSO4- A base is a substance which can behave as a proton acceptor.

Lorenzo at age 6 develops a classic childhood case of Adrenoleukodystrophy. Augusto and Michaela Odone work tirelessly with little assistance from the medical community and the parent support group to find a therapy to stop the progression of this devastating disease. In 2001 Elizabeth Spike‚ a high school biology teacher in Rochester‚ New York‚ chose to show a film
