Lysine has truly stumped me. What candy does this remind me of?! #aminoacids #biochemistry #science

Literally all my brain could think was 💩 and 💀. It was… not good. #biochemistry #aminoacids #cysteine

Leucine. Yet another white powdery substance. #biochemistry #aminoacids

Serine is name for spider silk?! Honestly I think these facts would have helped me remember them all in biochem! #aminoacids #biochemistry

Enzymes work best in the conditions they evolved in, and for lactose, that’s inside the small intestine which is about the same pH as milk ☝️🤓 #biochemistry #nutriton #enzyme #lactose #lactoseintolerance

No one made me do this. #phenylalanine #aminoacids #biochemistry

Carbohydrates aren’t always visible — but chemistry reveals them. 🧪 Add a few drops of iodine solution to a sample and watch the magic. If starch is present, the color shifts from brown to blue-black. This happens because iodine fits into the helical structure of amylose, forming a starch–iodine complex. No color change? No starch. Simple test. Clear concept. Strong foundation. #BiochemistryBasics #Carbohydrates #IodineTest #NEETBiology #CSIRNET

The McMurry reaction couples two carbonyl compounds to form an alkene through reductive deoxygenation mediated by low-valent titanium species. Reported by John E. McMurry in 1974, it provided a powerful synthetic route to alkenes from readily available ketones and aldehydes. Learn · Review · Repeat

“The equilibrium exchange of the halogen atom in alkyl halides for another halogen atom is known as the Finkelstein reaction” Finkelstein observed that when various alkyl chlorides and bromides (1°, 2°, 3°, benzylic, etc.) were boiled with a 15 wt% solution of NaI in acetone, the corresponding alkyl iodides were formed in good yield. Sterically hindered 2’ and 3’ alkyl halides can be converted to the alkyl iodides by treatment with NaI/CS2 in the presence of various Lewis acids (AlMe3, ZnCl2 FeCl3, etc.). Mechanism: Typical SN2 reaction where the filled orbital of nucleophile (halide ion) interacts with the σ* orbital of the carbon-halogen bond, and the reaction proceeds with an overall inversion of configuration. Equilibrium can be shifted toward the direction of halogen-exchange according to Le Chatelier principle (NaBr and NaCl precipitates). Driving force for the reaction is removal of one of the nucleophiles from the equilibrium as an insoluble salt. #organicsynthesis #organicchemistrylearning #drughunting #organicchemistry #drugdiscovery

tRNA delivers amino acids based on codons! AUG always starts polypeptide chains with methionine. Little drops of threonine from ACA codons. Science in motion! #Biology #ScienceExplained #GeneExpression #ProteinSynthesis #MolecularBiology #Education #LearnOnReels
