Glycoproteins and Their Benefits For Health


In 1999 the Nobel Prize in Physiology or Medicine was awarded to Gunter Blobel for the invention that proteins have intrinsic indicators that govern their transport and localisation within the cell. It was based mostly on this analysis into how cells use these indicators that the features of glycoproteins have been found.

Glycoproteins are molecules which have a sugars and protein bonded collectively. The sugar chains of glycoproteins play a job in figuring out their vacation spot within the cell or physique. The bonding of sugars to proteins to kind glycoproteins considerably alters the properties of those proteins.

There are eight sugars that predominantly bond with proteins to kind glycoproteins, these are: xylose, galactose, glucose, mannose, fucose, N-acetylgalactosamine, N-acetylglucosamine and N-acetylneuraminic acid.


Glycans include biologic info and are the precise sequence of sugars in a glycoprotein that decide its recognition and interplay with different molecules within the cell, typically leading to a biologic impact or response. These impart their perform to glycoproteins.

Glycoproteins have many features within the human physique. A couple of features of curiosity is that they’re used structurally within the physique to kind some forms of collagen; or are concerned in cell-cell interactions, equivalent to within the proteins concerned in sperm-egg interactions throughout fertilisation or how cells stick collectively to kind tissues and talk with one another. They additionally perform in cell signalling.

Cell signaling is the associated examine of how wholesome cells reply appropriately in well being to varied stimuli e.g., hormones, development components, medication, cell-cell contact, and so forth. Glycoproteins on the floor of 1 cell bind to glycoprotein receptors on one other cell, which permits the cells to speak with each other. These communications then lead to different mobile occasions, equivalent to secretion of bioactive substances, killing of micro organism and cell particles, inhibition of adherence crucial for bacterial an infection. Conversely, the responses could also be inappropriate in sure ailments, equivalent to most cancers and most cancers cell metastasis.

Lectins, for instance, are proteins that selectively bind glycans. One lectin will acknowledge and bind mannose on the finish of a glycan, whereas others will acknowledge and bind to glycans containing fucose, galactose, or different sugars. A category of lectins referred to as selectins helps white blood cells to websites of irritation.


Glyconutrition is the supplementation the eight principal sugars which might be wanted by the physique to from glycoproteins. They are thought-about important vitamins, a lot the identical as important amino acids or important fatty acids, which suggests it’s a must to get them out of your weight-reduction plan.


Metabolic pathways exist for synthesis of non-glucose sugars from glucose, and it has lengthy been thought that glucose is an important dietary sugar; it has lately been proven that glycoprotein formation really desire to make the most of non-glucose important sugars (e.g. mannose) offered within the weight-reduction plan as substrates. In truth, if solely glucose is provided, the liver severely malfunctions, as a result of a scarcity of the opposite important sugars, indicating that the physique merely can not synthesize all the opposite important sugars from glucose to the extent that they’re wanted.


These eight sugars will solely seem in fruit and greens which might be vine ripened; this primarily means the fruit or vegetable ripens on the plant. However it is a course of that now not occurs in trendy agriculture. Much of our fruit and greens are picked when inexperienced, and artificially ripened previous to being placed on the cabinets on the grocery store. This means sadly that we have now to complement with them to acquire the eight crucial sugars important for well being.


As may be seen from the previous paragraphs, glycoproteins are important within the well being and upkeep of the human physique; a lot so, that intensive analysis has been performed on them in relation to sure ailments.

Implications for most cancers. Research has proven that there are adjustments to the sugars in glycoproteins of most cancers cells. These adjustments relate to adhesion properties of the most cancers cell and their capacity to stick to different cells within the physique or to metastasize. These altered glycoproteins may additionally relate to the power of the tumour to keep away from the responses of the immune system. Altered glycoproteins have been present in intestinal, pancreatic, liver, ovarian, prostate, and lung cancers.

Glycoproteins which have mannose of their construction has been proven to activate macrophages (an immune system cell), one of the necessary cells concerned in preventing most cancers. Also, the discharge of drugs from the macrophage is stimulated, which prompts pure killer cells (one other immune system cell concerned within the elimination of most cancers cells).

Implications for persistent fatigue syndrome and fibromyalgia. The precept signs of those situations embody muscle and joint ache, persistent fatigue, non-restorative sleep, persistent stress, migraine complications, and bowel and bladder irritability. The immune, endocrine (e.g. hormones), nervous (e.g. neurotransmitters, sleep pathways, psychological stress), and muscular (e.g. tender factors) techniques of the physique are all intimately concerned in these syndromes. Glycoproteins all play necessary roles in sustaining the well being and regular functioning of those techniques. Therefore supplementation with the eight easy sugars could positively influence on these syndromes.

Implications for irritation. Inflammation in itself shouldn’t be a illness, however relatively happens as results of tissue damage, equivalent to in bacterial an infection. Inflammation is normally useful to the person. However, this course of can get out of hand, as many ailments that have an effect on us are inflammatory in origin. As famous earlier, glycoproteins assist information immune cells to websites of irritation, in addition to they’re concerned within the means of permitting the immune cells to traverse the wall of blood vessels and enter the tissues on the web site of irritation.

Implications for peptic ulcers induced by Helicobacter pylori micro organism. Helicobacter pylori connect to 2 particular glycans on the cell surfaces of abdomen and duodenum. Once hooked up, the micro organism launch numerous enzymes that together with the acidic content material of the abdomen, ends in ulceration. Glycans are the primary molecules encountered by micro organism as a way to connect to cells. The eight sugars compete with micro organism for attachment to the glycans, and is a technique of blocking bacterial adherence.

Implications for stress. Research has proven that the formation of glycoproteins is considerably altered in numerous forms of stress, equivalent to in an infection, irritation and trauma.

Stress exists in lots of varieties, whether or not it’s psychological (as in nervous system dysfunction), environmental (as in excessive warmth or chemical toxins) or physicochemical (equivalent to in train). Glycoproteins forestall and restore injury to cells on account of these stresses.

Implications for Rheumatoid Arthritis. Rheumatoid arthritis (RA) is an inflammatory situation, and glyconutritions are identified to positively have an effect on irritation.

RA is an autoimmune situation, which means that antibodies are produced towards the physique’s personal tissues; this suggests that there’s a miscommunication between the immune system and the joint tissue. The irregular antibody produced is IgG, which has lower than regular quantities of galactose in its construction, and throughout remission this discount of galactose is reversed.

It has additionally been discovered that fucose is markedly decreased in RA sufferers. The better the deficiency of fucose in RA sufferers, the extra extreme the signs will likely be.

Supplementation of the required sugars, i.e. galactose and fucose, wanted by the physique to fight this sickness.

On the subject of auto-immune situations I wish to share a case of mine efficiently handled with the ise of those eight important sugars. Mrs T. offered to me with discoid lupus, which is a milder case of lupus which predominantly impacts the pores and skin, inflicting onerous ‘scar-like’ lesions. She had these lesions unfold all through the physique. I prescribed the sugars in a powder, 5g/day. After utilizing them for a interval of three months, all of her pores and skin lesions have been fully healed, in addition to her anti nuclear issue had dropped proper all the way down to regular blood ranges.

In my private expertise with these sugars I’ve discovered that they’re the very best in treating auto-immune situations equivalent to lupus, rheumatoid arthritis, a number of sclerosis and so forth. If you may have any questions concerning the usage of the eight sugars on your well being situation/s, be happy to contact me.


As may be seen from the above article, correct glycoprotein formation performs an necessary function on the upkeep of well being and combating of illness. Sadly six of the eight sugars now not seem in our meals provide, and it has change into essential to complement with these sugars with a purpose to preserve optimum well being.
