Griffith college Tri1 2023/1015 MSC (Chem2)16 [WEEK10] Enzymes, Metals in Biological System & Chemistry of Medicine https://youtu.be/yk14dOOvwMk https://www.youtube.com/watch?v=H_1ULIKzwfA HOLOENZYME = enzyme + cofactor/coenzyme ENZYMES - ARTICULATE SESSION Enzymes are proteins that speed up biological reactions. Without enzymes the biological processes that support life would not be fast enough to sustain our life. What are enzymes? Most enzymes are proteins (although some are RNAs are enzymes too!). Non-pro.. 2023. 5. 13. [WEEK6]Chemistry of Food- Carbohydrates & Carbohydrates -Amilopectin -> 80% of starch / slightly branced -Amilyose -> 20% of starch/ chain -Glycogen -> highly branched *Branched means it can produce energy easily (Enzymes can only break down starch at the end of the chain = more branch = more place for enzyme to work on) MINI LECTURE PART1 1) number of carbon atoms in the molecule => pentose(ribose/deoxyribose) , hexose (glucose/galactose/fructose) 2.. 2023. 4. 2. [WEEK6] Stereoisomerism MINI LECTURES Isomerism -differ in how the atoms are connected => structural isomers -differ in how the connected atoms are arranged in space => stereoisomers *Stereoisomers -cis or trans geometric isomers -optical isomers (have the ability to rotate the plane of plane-polarised light) -Optical activity: the ability of a substance to rotate plane-polarized light to the right or left (Right: dext.. 2023. 3. 31. [WEEK5] Carboxylic Acids, Esters Mini lectures Carboxylic acid Esters Why esters are non polar????? Introduction of carboxylic acid Physical properties of carboxylic acid The relative high boiling points of carboxylic acids are due to intermolecular attractions resulting from hydrogen bonding. For example, the boiling point of ethanoic acid is 119 °C, higher than the boiling point of ethanol, 78 °C. as the length of the carbon .. 2023. 3. 30. 이전 1 2 3 4 다음 반응형
