Carbohydrates Digestion ๐๐
- What are they? Carbs are digested into sugars: glucose, fructose, and galactose.
- Where does it start? Mouth.
- Fun Fact: Ever noticed bread tasting a bit sweet if you chew it for a while? That's the amylase in your saliva breaking down the starches!
- Stomach's role? Not much. Its low pH inhibits the enzyme working on carbs.
- Main action spot: Upper part of the small intestine with the help of pancreatic amylase.
- Key Enzymes and What They Do
- Amylase - breaks carbs into maltose, maltotriose, and α-limit dextrin.
- Maltase & Isomaltase - convert above into glucose.
- Special enzymes in the small intestine work on undigested sucrose and lactose, turning them into glucose + fructose and glucose + galactose, respectively.
How Carbs Travel ๐ค๏ธ
- Mostly absorbed in the upper/middle part of the small intestine.
- Glucose and galactose need a "taxi" called sodium glucose co-transporter (SGLT) which requires energy.
- Fructose takes a more chill route through facilitated diffusion with the help of GLUT5.
- Real World Analogy: Think of glucose and galactose as VIPs who need a special escort (SGLT) to get through a crowd, while fructose just smoothly blends in with the help of its pal, GLUT5.
Some Carbs That Play Hide and Seek ๐
- Some carbs avoid digestion in the small intestine. Why? Their bonds can't be broken by our enzymes or they're hidden inside things like fiber.
- These carbs party in the large intestine where bacteria feast on them, breaking them down to short-chain fatty acids, which our body can absorb.
