How to Convert Alkenes to Alcohols through Hydration

The mechanism for hydroboration involves the cyclic transition state shown in the next figure. Borane adds to the least substituted side of the double bond to make the alkyl borane. Because the addition is concerted (both the hydrogen and BH 2 are added simultaneously), the borane and hydrogen must add to the same face of the carbon-carbon bond (two groups adding to the same face of a double Get price

Metabolism and Physiological Effects of Cyclic Fatty Acids

They also affect the activities of lipid-synthesising and -oxidizing enzymes in rat liver. Based on the data presented in this short review and considering that oxidation and elimination are powerful processes for excretion of CFAM and their low amounts in the diet, we suggest that cyclic fatty acids are not a major concern for human safety when oils are used under normal frying conditions.

Photosynthesis Problem Set 1

1996/9/29PS II is not involved in cyclic photophosphorylation A photon of light energy absorbed by photosystem I results in the excited state P700* pigment which undergoes oxidation to P700 + . Electrons are cycled from photosystem I via the photosynthetic electron transport chain back to the reaction center, where P700 + is reduced to P700. Get price

Electron Transport Chain (With Diagram)

ADVERTISEMENTS: In this article we will discuss about the subject-matter and components of electron transport chain. Subject Matter of Electron Transport Chain: The primary function in photosynthesis is the raising of an electron to a higher energy level in chlorophyll. Then the electron is transferred to an acceptor. It is, as if, there is a [] Get price

Preparation of Carboxylic Acids

Remember: Mild oxidizing agents such as manganese dioxide (MnO 2) and Tollen's reagent [Ag(NH 3) 2 + OH −] are only strong enough to oxidize alcohols to aldehydes. The oxidation of alkyl benzenes Alkyl groups that contain benzylic hydrogens —hydrogen(s) on a carbon α to a benzene ring—undergo oxidation to acids with strong oxidizing agents. Get price

Roles of the Cyclic Electron Flow Around PSI (CEF

Abstract To assess the roles of the cyclic electron flow around PSI (CEF-PSI) and O 2-dependent alternative pathways including the water–water cycle in fluctuating light, we grew the wild type and pgr5 mutant of Arabidopsis thaliana in constant light, and measured Chl fluorescence and P700 parameters in their leaves in the fluctuating light alternating between 240 (HL) and 30 mol photons m Get price

Deconstructive fluorination of cyclic amines by carbon

Carbon-carbon single bonds are fairly unreactive when they are not strained in a tight ring. Roque et al. now report that a silver salt can cleave C–C bonds in unstrained cyclic amines such as pyrrolidines and piperidines. Paired with an electrophilic fluorine source in aqueous solution, the silver first oxidizes the α carbon adjacent to the nitrogen. Ring-opening fluorination of the β Get price

Antioxidant Compounds and Their Antioxidant Mechanism

An antioxidant is a substance that at low concentrations delays or prevents oxidation of a substrate. Antioxidant compounds act through several chemical mechanisms: hydrogen atom transfer (HAT), single electron transfer (SET), and the ability to chelate transition metals. The importance of antioxidant mechanisms is to understand the biological meaning of antioxidants, their possible uses Get price

The big idea about cyclic electron flow is that it combines Photosystem I's light trapping machinery with Photosystem II's electron transport chain. Here's how it works. Light shining on Photosystem I (number "1" at left), excites electrons, which bounce around the photosystem (represented by "2") until they reach reaction center p700. Get price
