Cholesterol synthesis primarily occurs in the liver and involves a complex series of enzymatic reactions, starting from acetyl-CoA and culminating in the production of cholesterol. This process is tightly regulated by various factors, including dietary intake, hormonal signals, and feedback mechanisms from cholesterol levels themselves. Excess cholesterol can be converted into bile acids or stored in lipid droplets, while low levels trigger increased synthesis and uptake from dietary sources. Overall, cholesterol plays vital roles in cell membrane structure, hormone production, and lipid metabolism.
the smooth endoplasmic reticulum has the role in cholesterol synthesis, fat metabolism, and detoxification of drugs
Yes, cholesterol is important in the synthesis of sex hormones.
Biosynthesis in the"liver" accounts for approximately 10% of the cholesterol produced each day. Cholesterol synthesis occurs in the cytoplasm and microsomes.Related link:http://themedicalbiochemistrypage.org/cholesterol.html
NADPH2
The HMG-CoA Reductase reaction is rate-limiting for cholesterol synthesis.

HMG-CoA reductase is an enzyme that catalyzes the rate-limiting step in cholesterol biosynthesis. It converts HMG-CoA to mevalonate, which is a key intermediate in the synthesis of cholesterol and other important molecules in the body. Inhibitors of HMG-CoA reductase are commonly used as cholesterol-lowering medications.
Cholesterol synthesis from acetyl CoA molecules
NADPH2
The building block of steroid hormones and vitamin D is cholesterol. Cholesterol serves as the precursor molecule for the synthesis of these important biological compounds in the body.
Consuming garlic may help lower cholesterol levels in the body by reducing the production of cholesterol and promoting its breakdown. Garlic contains compounds that can inhibit enzymes involved in cholesterol synthesis, leading to a decrease in overall cholesterol levels.
Well, cholesterol bio-synthesis is controlled by the regulation of HMG-CoA Reductase. This happens near the beginning of the pathway, so in my opinion would seem to be the key step in the process. There are actually 5 steps considered to be the bio-synthesis pathway of cholesterol. They all seem to me as important but it's just my opinion. Hope it helps.
