What are the differences between cholesterol and ergosterole?​

Chemistry
1 answer:
Marat540 [252]3 years ago
5 0
The difference between ergosterol and cholesterol is much more obvious in their interactions with POPC and DOPC. Whereas cholesterol induces a strong condensing effect that thickens both POPC and DOPC bilayers, ergosterol shows no condensing effect in POPC and DOPC at all.

a grignard synthesis begins with 6.00 g of bromobenzene and ends with 3.56 g benzoic acid. what is the percent yield of the benz
Paha777 [63]

The percent yield of the benzoic acid is<u> 59.33 %</u>

Grignard averages should not contain acidic hydrogens as they are destroyed when they are on the compound. A Grignard reaction is an organometallic chemical reaction in which an alkyl, allyl, vinyl, or aryl magnesium halide adds to the carbonyl group of an aldehyde or ketone. This reaction is important for the formation of carbon-carbon bonds.

<u>Calculation:-</u>

percentage yield = calculated/theoretical

                            =  3.56/6.00 × 100

                           = 59.33 %

The carbon atoms of Grignard reagents are partially negatively charged, so they resemble carbanions and react with electrophiles. Grignard reagents are highly reactive reactants used synthetically to form new carbon-carbon bonds. Grignard reagents are made by reacting alkyl halides with magnesium in the presence of dry ether. Chemistry: Grignards are very important reagents in chemistry as they can be used to form a wide variety of compounds.

Do Alkali Metal Compounds form precipitates? And Why?
Alexeev081 [22]

Answer:

Alkali metal hydroxides can be used to test the identity of metals in certain salts. The colour of the precipitate will help identify the metal : Calcium hydroxide is soluble; no precipitate is formed.

Draw the addition products formed when one equivalent of HBr reacts with 2,4-hexadiene. (Draw a single product for each. Ignore
Tems11 [23]

Answer:

The products are 4-bromo-2-hexene and 2-bromo-3-hexene

Explanation:

The reaction starts between terminal carbon of of of the double bonds and H^{+}. After attaching H^{+} to the carbon, one double bond disapears leaveing nearby CH positively charged. This intermediate is a resonance hybrid of two possible structures. Reaction of bromide at one of the carbons gives the 1,2-addition product and at the other carbon gives 1,4-addition product.
