Mineraloid substances possess chemical compositions that vary beyond the generally accepted ranges for specific minerals, for example, obsidian is an amorphous glass and not a true crystal; lignite is derived from the decay of wood under extreme pressure underground; and opal is a mineraloid substance because of its non-crystalline nature.
Oncotic pressure, or colloid osmotic-pressure, is a type of osmotic pressure induced by the plasma proteins, notably albumin, [1] in a blood vessel's plasma (or any other body fluid such as blood and lymph) that causes a pull on fluid back into the capillary.
Further hemoglobin crystal structures at higher resolution (PDB 1MHB, 1DHB) soon showed the coupled change of both local and quaternary conformation between the oxy and deoxy states of hemoglobin, [5] which explains the cooperativity of oxygen binding in the blood and the allosteric effect of factors such as pH and DPG. For decades hemoglobin ...
A crystal's crystallographic forms are sets of possible faces of the crystal that are related by one of the symmetries of the crystal. For example, crystals of galena often take the shape of cubes, and the six faces of the cube belong to a crystallographic form that displays one of the symmetries of the isometric crystal system. Galena also ...
Emulsion or Liquid crystal Examples: milk, mayonnaise, ... Colloids preserve a high colloid osmotic pressure in the blood, ... a non-profit organization.
The safety of sugar substitutes is once again being called into question. Xylitol is associated with an increased risk of heart attack and stroke, according to new Cleveland Clinic research.
Biomineralization, biologically controlled mineralization, occurs when crystal morphology, growth, composition, and location are completely controlled by the cellular processes of a specific organism. Examples include the shells of invertebrates, such as molluscs and brachiopods. Additionally, the mineralization of collagen provides crucial ...
A cholesterol crystal is a solid, crystalline form of cholesterol found in gallstones and atherosclerosis. Gallstones occurring in industrialized societies typically contain more than 70-90% cholesterol by weight, much of which is crystalline. [ 1 ]
