Find the Grignard reagent and what carbonyl compound might you start with to prepare the given alcohol. Identify the reactant from which the given molecule was prepared. If an acetal, identify the carbonyl compound and the alcohol; if an imine, identify the carbonyl compound and...
S.Note: if multiple chirality centers are present, indicate the stereochemical designations as: RR,SS,RS,or SR. (Other terms used for chirality center include chiral center, stereocenter, and stereogenic center.)
For a sugar drawn in Fischer projection with the most oxidised group at top a chiral center with OH on the right will be R. and a chiral carbon with OH on the left will be S. Answer and Explanation:1 To find the enantiomer of a molecule drawn as a Fischer projection, simply exchange...
Unlike humans, sea turtles and other reptiles like crocodiles do not have sex chromosomes. Their sex is defined during development by the incubation environment. In sea turtles, sex is determined by the nest's temperature: warmer temperatures produce fem
A team of scientists led by Prof. Kang Le at the Institute of Zoology, Chinese Academy of Sciences, has reported an unprecedented animal defense mechanism by which an olfactory aposematic (warning) signal can be converted to a hypertoxic chemical to faci
the next is applied. in brief they are: (1) higher atomic number has priority (2) higher atomic mass has priority (3) when considering double bonds with tetraligand atoms "seqcis" = "Z" > "seqtrans"="E" (4) refers to chiral centers ...
in C. elegans, a nematode worm used as a model in aging research. The increase in lifespan would be the equivalent of a human living for 400 or 500 years. The discovery of the synergistic effect opens the door to new, more effective anti-aging therapies. Credit: MDI Biological Laboratory...
Such a regulator may be a regulatory protein, small molecule and the like.As used herein, the term “regulatory event” is intended to mean a modifier of the flux through a reaction that is independent of the amount of reactants available to the reaction. A modification included in the ...
Antkey photographs, like this one of the Paratrechina longicornis worker with a larva, help viewers identify the ants they encounter. Credit: Eli Sarnat However, Antkey uses a more interactive system called a "lucid key" to make the process easier. ...
