Question 18: Triglycerides are made of a glycerol with each carbon attached to one fatty acid (total 3 fatty acids + 1 glycerol).
1. Adipose triacylglyerol lipase (ATGL) cleaves fatty acid from the 1st carbon producing a free fatty acid (FFA) and 2,3-diacyl glycerol (DAG).
2. Hormone-sensitive lipase (HSL) acts on DAG at 3rd carbon to form a FFA and 2-monoacyl glycerol (MAG).
3. Monoacyl glycerol lipase (MGL) acts on MAG to form a FFA and glycerol.
These FFAs undergo β-oxidation to generate acetyl-CoA which produce energy via the Krebs cycle and electron transport chain (ETC).
Glycerol enters glycolysis as glyceraldehyde-3-phosphate.
Due to time constraint, I am unable to answer all the questions now. Kindly repost rest of the questions separately or mention “answer all the questions”. As per the Chegg guidelines, I am only supposed to answer the 1st question (in case of multiple questions) or first 4 questions (in case of multiple subparts). If you have any specific doubts, I can answer in the comments.
