PHYSCI 5 Lecture Notes - Lecture 5: Polysaccharide, Starch, Ice Cream
Overview:
● Talked about the monosaccharides, disaccharides, and polysaccharides
● “Sugar is bad” - talking about mono and di
Polysaccharides→ carbohydrates
Fiber is not perfectly digestible.
Starch 100%, fiber 20-50% FDA rules, so fiber is 1g gives you 4 calories.
● Natural sugar = meh
○ Sugar found in food/fruit
○ unaltered
● Added sugar = very bad
○ Not natural
○ packaged/adding more sugar
○ Orange juice
○ Added fructose rather than glucose - it’s sweeter so less product needed
to get same sweetness
● Refined sugar = horrible
○ Changing the sugar, the natural composition of the sugar and adding it
into it to make the food extremely sweet
○ Candy / Ice cream
○ Packaged
Corn (get subsidies from government)
● Has lots of polysaccharides (starch-100% many glucose)
● Alter chemically and turn some starch→ fructose + glucose
○ Sweeter and add to food
○ High fructose corn syrup
■ Lots of sugar, so easy to overload on
■ Metabolized differently
○
○ Make liver work harder than normal → unaware person and were consuming this
○ Liver can only output limited amt of glucose → so with the extra, converts it to fat
and that fat is stored into the adipose tissue → stuck in blood vessel
■ Plasma fat or serum fat

The good sugar (bad is fructose)

Document Summary
Talked about the monosaccharides, disaccharides, and polysaccharides. Sugar is bad - talking about mono and di. Starch 100%, fiber 20-50% fda rules, so fiber is 1g gives you 4 calories. Added fructose rather than glucose - it"s sweeter so less product needed to get same sweetness. Changing the sugar, the natural composition of the sugar and adding it into it to make the food extremely sweet. Has lots of polysaccharides (starch-100% many glucose) Alter chemically and turn some starch fructose + glucose. Lots of sugar, so easy to overload on. Make liver work harder than normal unaware person and were consuming this. Liver can only output limited amt of glucose so with the extra, converts it to fat and that fat is stored into the adipose tissue stuck in blood vessel. Vegetables become so good because lots of veggies because you"re not getting a lot of calories or sugar because the content of sugar per veggies.
