The oligosaccharides found on the A, B, and H antigen occur on the non-reducing ends of the oligosaccharide. The H antigen (which indicates an O blood type) serves as a precursor for the A and B antigen. [7] Therefore, a person with A blood type will have the A antigen and H antigen present on the glycolipids of the red blood cell plasma membrane.
One example of glycoproteins found in the body is mucins, which are secreted in the mucus of the respiratory and digestive tracts. The sugars when attached to mucins give them considerable water-holding capacity and also make them resistant to proteolysis by digestive enzymes. Glycoproteins are important for white blood cell recognition.

Type 1 is found in secretions and in the serum. Type 2 is found exclusively on the surface of red blood cells. No type 1 oligosaccharide is found on RBCs. Unbranched type 1 and 2 oligosaccharides represent i antigen. Branched type 1 and 2 oligosaccharides are I antigens. [2] In neonates, i antigen oligosaccharides predominate (high in cord ...
Many foods naturally high in inulin or fructo-oligosaccharides such as chicory, garlic, and leek have been seen as "stimulants of good health" for centuries. [42] As of 2013, no regulatory authority had permitted health claims in the marketing of prebiotics as a class.
Pie charts of typical human body composition by percent of mass, and by percent of atomic composition (atomic percent) Body composition may be analyzed in various ways. This can be done in terms of the chemical elements present, or by molecular structure e.g., water , protein , fats (or lipids ), hydroxyapatite (in bones), carbohydrates (such ...
The basics: Choose foods based on your blood type: O—high protein; A—no meat; B—avoid chicken, tomatoes, peanuts and some grains; AB—eat seafood, tofu, dairy and green vegetables. Avoid ...
Blood types are an example of how glycolipids on cell membranes mediate cell interactions with the surrounding environment. The four main human blood types (A, B, AB, O) are determined by the oligosaccharide attached to a specific glycolipid on the surface of red blood cells, which acts as an antigen. The unmodified antigen, called the H ...
