Bioquímica del COLESTEROL | Síntesis endógena explicada FÁCIL | Metabolismo de SALES BILIARES

In this biochemistry lesson, I'll explain the biochemistry of cholesterol in a simple, clear, and step-by-step way. You'll understand what cholesterol is, how it's synthesized endogenously from acetyl-CoA, how HMG-CoA reductase is regulated, and how cholesterol is transformed into bile acids and bile salts. 📌 FREE NOTES Search the keyword "cholesterol" on Instagram and I'll send you the link to download the free notes. 🔗 Instagram: https://ig.me/m/nadtochiy.roman 🔗 TikTok: 🧠 In this video we see: • what cholesterol is • cholesterol as a non-saponifiable lipid • cyclopentanoperhydrophenanthrene derivatives • cholesterol homeostasis and balance • sources of cholesterol in the body • endogenous cholesterol synthesis • dietary cholesterol • cholesterol elimination via bile • free cholesterol and bile acids • main functions of cholesterol • cholesterol in the cell membrane • cholesterol as a precursor of steroid hormones • cholesterol as a precursor of vitamin D • cholesterol as a precursor of bile acids • cholesterol synthesis from acetyl-CoA • relationship between acetyl-CoA, fatty acids, and cholesterol • ATP and NADPH consumption in cholesterol biosynthesis • HMG-CoA reductase as a key enzyme • regulation of endogenous cholesterol synthesis • how statins work • regulation by cholesterol, bile acids, Insulin, glucagon, and adrenaline • Formation of primary bile acids • Cholic acid and chenodeoxycholic acid • Conjugation with glycine and taurine • Glycocholic acid and taurocholic acid • Secondary bile acids • Deoxycholic acid, lithocholic acid, and 7-ketolithocholic acid • Enterohepatic circulation of bile acids • Regulation of 7α-hydroxylase • Bile salt metabolism explained simply If this lesson on cholesterol biochemistry, endogenous cholesterol synthesis, and bile salt metabolism helped you, please like, subscribe, and share it with someone else studying biochemistry. #Biochemistry #Cholesterol #Lipids
