NADPH and oxygen which is incorporated it into the fatty acid (Figure 1) . This leaves NADP+ and water as byproducts and the methyl group converted to a hydroxyl group or alcohol as the product. The alcohol is then oxidized by a dehydrogenase into an aldehyde which is oxidized into dicarboxylic acids. The dicarboxylic acids form CoA‚ go through beta-oxidation‚ and produce adipic and succinic acids which can be excreted in the

Oxidation can be observed through the loss of electrons or an increase in oxidation state by an atom‚ ion or molecule. Reduction describes the gain of electrons or decrease in oxidation state

INTRODUCING ESTERS This page explains what esters are and looks at their simple physical properties such as solubility and boiling points. It includes an introduction to more complicated naturally-occurring esters like animal and vegetable fats and oils. What are esters? Esters are derived from carboxylic acids. A carboxylic acid contains the -COOH group‚ and in an ester the hydrogen in this group is replaced by a hydrocarbon group of some kind. This could be an alkyl group like methyl

Organic chemistry Organic chemistry is one of the ‘branches’ of chemistry and is seen as distinct from other branches‚ such as inorganic and physical chemistry. It can be described as the chemistry living processes (often referred to as biochemistry) but extends beyond that. It focuses almost entirely on the chemistry of covalently bonded carbon molecules and as well as life processes‚ it includes the chemistry of other types of compounds‚ including plastics‚ petrochemicals‚ drugs and paint
Premium Alkene Functional group Hydrocarbon
In the IUPAC system of nomenclature‚ functional groups are normally designated in one of two ways. The presence of the function may be indicated by a characteristic suffix and a location number. This is common for the carbon-carbon double and triple bonds which have the respective suffixes ene and yne. Halogens‚ on the other hand‚ do not have a suffix and are named as substituents‚ for example: (CH3)2C=CHCHClCH3 is 4-chloro-2-methyl-2-pentene. If you are uncertain about the IUPAC rules for nomenclature

Increasing the oxidation state or oxidation number of the carbon atom is called an oxidation reaction. This is done in two ways: 1) Increasing the number of carbon-O bonds (or any more electronegative atom than C). 2) Decrease number of C-H bonds. Aldehydes and ketones can be synthesized by the oxidation of primary or secondary alcohols. Discussion & Conclusion: The first part of this experiment examined oxidation reaction which was used to
