Title: Glyconutrients
1Glyconutrients
2Glycoprotein
- Glycoproteins are proteins that contain
oligosaccharide chains (glycans) covalently
attached to their polypeptide side-chains. - The process of attaching the glycans is known as
glycosalation. - The sugar groups attached to glycoprotein can
assist in protein folding or improve a proteins
stability.
3Functions of Glycoproteins
Function Glycoprotein
Structural Molecule Collagen
Lubricant and Protective Agent Mucins
Transport Molecule Transferrin, ceruloplasmin
Immunologic Molecule Immunoglobins, histocompatibility antigens
Enzyme Various, e.g alkaline phosphatase
Cell Attachment-recognition site Proteins involved in cell to cellc ommunication
Interact with specific carbohydrates Lectins, selectins (cell adhesion lectins), antibodies
4Functions of Glycoproteins
Function Glycoprotein
Receptor Various Proteins in hormone and drug action
Affect folding of certain proteins Calnexin, Calreticulin
Regulation of development Notch and its analogs, key proteins in development
Hemostasis (and thrombosis) Specific glycoproteins on the surface membranes of platelets
5Examples
- Mucins mucins are secreted in the mucus of the
respiratory and digestive tracts. The sugars
attached to the mucins give them considerable
water-holding capacity and make them resistant to
proteolysis by digestive enzymes. - Immune System Glycoproteins antibodies, major
histocompatibility complex (MHC) (interacts with
T-cells)
6Examples
- Glycoproteins in platelets.
- Structural glycoproteins
7Hormones That Are Glycoproteins
- Follicle-stimulating hormone
- Luteinizing hormone
- Thyroid Stimulating hormone
- Human chorionic gonadotropin
- Alpha-fetoprotein
- Erythropoietin

9Eight Sugars in Glycoproteins
10Glucose
- Readily available in our diets.
- Converted from white sugar, fructose, and starchy
foods. - Usually oversupplied in our diets from sugar
cane, rice, corn, potatoes, wheat, etc.
11Galactose
- Readily available in our diets.
- Obtained from the conversion of lactose (milk
sugar).
12Fucose
- NOT readily available in our diets.
- Found in breast milk.
- Present in several medicinal mushrooms.
- Benefits the immune system.
13Mannose
- NOT readily available in our diets.
- Involved in cellular interactions.
- Studies show it can lower blood sugar levels.
- Assists the immune system to defend against
microbial pathogens. - Anti-inflammatory effect.
14Xylose
- Not readily available in our diets.
- Present in some sugarless gums and candies.
- Added to some nasal sprays to discourage the
binding of allergens and pathogens to mucuos
membranes. - Anti-bacterial and anti-fungal properties.
- May help prevent certain cancers.
15N-acetyl-neuraminic acid
- NOT readily available in our diet.
- Present in breast milk.
- Assists in brain development.
- Boosts immune function.
- Anti-viral properties.
16N-acetyl-glucosamine
- NOT readily available in our diets.
- Beneficial for cartilage regeneration and joint
inflammation. - Glucosamine comes from this compound.
- Deficiencies have been linked to diseases of the
bowel.
17N-acetyl-galactosamine
- NOT readily available in the diet.
- May inhibit the growth of some tumors.
- Assists in cell to cell communication.
18Breast Milk
- Breast milk contains five of the essential
sugars. - Fucose
- Galactose
- N-acetylneuraminic acid
- N-acetylglucosamine
- Glucose
19Aloe Vera
- Aloe vera contains mannose , galactose, and
arabinose.
20Arabinogalactan
- Saps and gums of trees contain many
glyconutrients. - Arabinogalactin can be obtained from the Larix
decidua or larch tree. - It is also found in fruits and vegetables such as
tomatoes, corn, carrots, coconut. - It is in the herb echinacea.
21Echinacea
- Echinacea contains the following glyconutrients
- Arabinogalactan
- Galactose
- Arabinose
22Astragalus Gummifer
- The stems and branches of astragalus shrubs are
rich in galactose, arabinose, xylose, fucose,
rhamnose, galcturonic acid, and proteins.
23Gum Acacia
- Extracted from the African acacia tree, gum
acacia contains arabinose, galactose, rhamnose,
and glucuronic acid.
24Gum Ghatti
- Obtained from the sap of the Indian sumac, gum
ghatti contains galactose, arabinose, mannose,
xylose, and glucuronic acid
25Limu Moui
- A marine vegetable native to Tonga, limu moui
contains the following glyconutrients - Galactose
- Mannose
- Xylose
26Medicinal Mushrooms and Beta Glucans
- Edible mushrooms contain an immune-enhancing
sugar compound known as lentinant (a
polysaccharide that contains beta-glucans)
27Pectins
- Pectins come from fruits like apples, pumpkins,
and tomatoes.
28Foods That Contain Glyconutrients
- Aloe vera
- Astralgus
- Saps
- Gums
- Garlic
- Certain mushrooms
- Yeasts
- Husks
- Breast milk
- Coconut meat
- Echinacea
- Maize
- Pectins from fruits
- Some algae
- Certain herbs
29Factors That Reduce Glyconutrients In Food
- Green harvests
- Processed foods
- Preservatives
- Increased toxins
- Limited variety of foods in our diet
30Glycoforms
- Virtually every cell in the body is covered with
hair-like glycoforms. - The sugar molecules form codes that allow cells
to communicate with one another.
31Glyconutrient Conversion
- A series of enzyme controlled steps converts one
glyconutrient sugar to another. - Enzyme conversions require energy.
- Toxins, stress, drugs, processed foods, lack of
enzymes, age, etc. can all inhibit an enzymes
ability to convert these glyconutrients. - It is more efficient to obtain glyconutrients in
the diet than to have to convert them.
32Glyconutrient Effects
- Raise the level of natural killer cells and
macrophages to fight against infectious
organisms. - Activate immune T-cell activity only when
invaders are present. - Decrease cell death in people suffering from
chronic fatigue syndrome.
33Glyconutrient Effects
- Elevate disease resistance in weakened
individuals. - Act as antioxidant compounds.
- Protect the body from toxin and pollution
exposure. - Slow premature aging.
34Glyconutrient Effects
- Decrease inflammation in diseases like rheumatoid
arthritis. - Helps immune cells recognize invaders due to a
mutual sugar exchange of information. - Enable cellular components to stick to each other
initiating the proper reactions.
