carbohydrates
BRING 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 guidelines
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)
optical
or
stereoisomer
of
glucose
corn syrup=glucose; HFCS=5% more fructose not bonded to glucose; sweeter; liver convert to glycogen & triglycerides.
Sugars in your diet: glucose, fructose, sucrose
polysaccharides
BANANA.
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.
saturation
MOLYMOD. Endomorph (round)-> meso, ecto.
Saturated vs. unsaturated fats (Bite-Sci-zed)
Omega 3 & Omega 6 fats: (polyunsaturated)
Google Home's substitute for butter: do you believe everything google says?
hydrogenation
Not all
FATS bad:
Omega=cis unsaturated. Grain-fed cattle, fast food (vegetable oil) -> too much
Omega6
-> inflammation.
Hydrogenation and trans fats
Omega 3 fatty acids: good fats
sterols
BRING 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
proteins
POLAR 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.
