Nutriton Skills Flashcards
Consequences of glucose metabolism imbalance (5 health conditions)?
- Ischemic heart disease
- hypertension
- Renal dysfunction
- Strokes
- Peripheral neuropathy
When can glucose enter your cell without insulin?
exercise
What are lipids essential for (5)?
- Cell membrane functions
- Energy metabolism & fuel creation
- Signal Transduction
- Delay aging & neurodegenerative diseases
- Prostaglandins
What do prostaglandins do (9)?
Regulate:
1. inflammation
2. vasoconstriction
3. platelet aggregation
4. hormones
5. cell growth
6. intra-ocular pressure
7. fever
8. GFR
9. sensitive spinal neurons to pain
Lipoprotein structure?
- Surface monolayer of phospholipids & free cholesterol & apolipoproteins
- Hydrophobic core of triglyceride & cholesterol esters
Anti-atherogenic vs pro-atherogenic lipoproteins?
Anti-atherogenic: HDL
Pro-atherogenic: chylomicron remnants, VLDL, IDL, LDL & lipoprotein a
Apolipoproteins functions (4)?
- Structural role
- Ligands for lipoprotein R
- guide formation of lipoproteins
- Activators/ inhibitors of enzymes involved in metabolism of lipoproteins.
Site of lipid storage (6)?
- Adipose tissue
- Muscle
- Lymph nodes (chylomicrons)
- Liver
- Blood
Lipid transport?
Hydrophobic lipid molecule attaches to protein to become hydrophilic and be transported via blood (lipoproteins)
Protein functions (6)?
- Growth/ development
- Cofactors
- Hormone synthesis
- Enzymes
- Building block of DNA & RNA
- Building block of muscle
3 routes of aas (protein metabolism)?
- Anabolism: build protein
- Catabolism: to produce carbon for energy or nitrogen & urea
- Excess was are discharged either in urine (NH4) or sweat
What are micronutrients?
Vitamins or minerals require in small amounts
Vitamin?
organic molecule that is an essential micronutrient that an organisms needs in small quantities for the proper functioning of its metabolism.
-can be water soluble or water insoluble
Water soluble vitamins? Examples (2)?
-mostly excreted in urine (metabolized by kidneys)
-usually safe
-toxic doses are extremely high
EXAMPLES: Vitamin C and all B vitamins.
B vitamins (8)?
B1 = Thiamine
B2 = Riboflavin
B3 = Niacin
B5 = Pantothenic Acid
B6 = Pyridoxine
B7 = Biotin
B9 = Folate
B12 = Cobalamin
Non true B vitamins (3)?
- Choline
- Inositol
- PABA
Not vitamins at all with B vitamin name (2)?
- Vitamin B17 = amygdalin, laetril
- Vitamin B15 = pangamic acid
Fat soluble vitamins? Example (4)?
-Metabolized by the liver
-stored in body for longer time
-can reach toxic levels after high doses in the body
EXAMPLES: A, D, E, K
Vitamin C roles (4)?
- cofactor: aas metabolism
- Support hormonal function
- collagen synthesis
- Antioxidant
Energy releasing B-vitamins (6)?
- Thiamin B1
- Riboflavin B2
- Niacin B3
- Pantothenic acid B5
- Pyridoxine B6
- Biotin B7
Hematopoetic vitamins (4)?
RBC formation
- Panthothenic acid B5
- Vitamin B6
- Folate B9
- Vitamin B12
What 2 vitamins share both energy releasing and hematopoietic functions?
Vitamin B5 (pantothenic acid) & vitamin B6 (Pyridoxin)
Macro-minerals? Examples (6)? Function?
-needed in higher quantities than micro minerals
Maintain bone & connective tissue health:
1. Calcium
2. Magnesium
3. phosphorus
Maintain electrolyte balance, muscle & nerve APs & function:
4. potassium
5. sodium
6. chorine
Microminerals? examples?
-needed in small quantities for their RDA
EXAMPLES:
iron, coper, zinc, selenium, chromium, iodine, manganese, molybdenum, fluoride, boron, silicon, vanadium
