carbohydratesBRING granola.
SAY simple, complex.
Why low CARB diet - count calories. USDA cannot say eat less meat!
Sugar alcohol=OH; these 1/2 carbs contribute to calories.
USDA MyPlate nutrition guidelinesCarbohydrates and sugars in your food
monosaccharides
Emphasize GLUCOSE high glycemic 100, banana 51. Alcohol=C-OH hydroxyl.
Only liver can break down fructose -> triglyceride (fat: plaque in artery), insulin resistance
Lactose = Glucose + GALACTOSE which is
C4 (4th from right) stereoisomer
(epimer) of glucose. polysaccharidesBANANA.
Discuss simple/complex SUGARS in energy
link.
Carbo-loading: glyco depletion/loading -> increase insulin/decrease glucose.
cellulose
RIGID
glycogen
Eat starch BANANA do you eat glycogen?
Nope MEAT has glycogen!
glucose
Note
GLYCOGEN discussion starts w GLUCOSE excess &
ends w FAT next topic.
fats
say FATTY acids; oil=liquid!
MOLYMOD. Energy density 2X sugars.
saturationMOLYMOD. Endomorph (round)-> meso, ecto.
Saturated vs. unsaturated fats (Bite-Sci-zed)
Omega 3 & Omega 6 (polyunsaturated) fatsGoogle Home's substitute for butter: do you believe everything google says?
hydrogenation
Omega=cis unsaturated. Grain-fed cattle, fast food (vegetable oils) -> too much Omega-6 -> inflammation.
Hydrogenation and trans fats
Omega 3 fatty acids: good fats
sterolsBRING p. butter, trail mix CANS for food labels.
Progesterone from LDL. HDL moves excess back to liver.
Cholesterol: LDL and HDL phospholipids
ERRATA phospholipid does NOT form monolayer sphere proteinsPOLAR oxygen. Wear
HANCOCK shirt.
Proteins: how much do you need?
protein-structure
Goblet cell secretes mucus (glycoproteins mostly carbohydrates).
Lentils + rice; corn + beans give all 9 essential amino acids.
enzyme
Say ACTIVE site, video also says reactants.
Diagram does not show lactose; use monosac figure=glucose+galactose
This shows 1 substrate -> 2 products.
Got Lactase? evolution of lactase persistence
nucleic_acids
sugar=carbohydrate. Details continued chap 6 DNA & expression.
RNA
methylation of U=T.
