Haemin crystals are needle-like structures that form when hemoglobin is oxidized and turns into methemoglobin. These crystals are commonly seen in blood smears from patients with certain types of hemolytic anemias or hemoglobinopathies. They are visualized under a microscope and their presence can aid in diagnosing these conditions.
Haemin crystals, also known as hematoidin crystals, are formed from the breakdown of red blood cells containing hemoglobin. They can be seen in urine sediment and are typically considered a normal finding in patients with hemolytic anemia or other conditions causing significant red blood cell destruction. Clinically, the presence of haemin crystals may indicate ongoing hemolysis or may be a sign of previous red blood cell breakdown.
The Nobel Prize in Chemistry 1930 was awarded to Hans Fischer for his researches into the constitution of haemin and chlorophyll and especially for his synthesis of haemin.
Cubic: crystals have 6 sides. Tetragonal: crystals have 4 sides. Orthorhombic: crystals have 3 unequal sides. Hexagonal: crystals have 6 sides. Monoclinic: crystals have 4 sides. Triclinic: crystals have no set number of sides.
Covalent crystals are not necessarily opaque. Think of diamond, pure quartz crystals, pure aluminium oxide crystals these all are colorless and transparent.
Borax crystals are specifically composed of the mineral borax, while other natural crystals can be formed from a wide variety of minerals such as quartz, calcite, or fluorite. Borax crystals have distinct properties and chemical composition that distinguish them from other natural crystals.

hemoglobin imparts red colour to blood. it has a conjugated protein part which makes the globin. the non protein part - haem is haematin. the haematin is made of porphyrin which is made by chelation with iron.

prosider:- prick the tip of finger with steriled needle. make a drop of blood in a clean slide and add a drop of water to in.so heamolysis can occure.Then add a drop of saline and heat the slide to evoparate the solution.later add a drop of glasial acitic acid and cover it with coverslip.Heat gentely over the spirit lamp till the bubbles occures.Add another drop of glacial acitic acid to the slide of coverslip.Allow it cool and observe under the microscope. Result:- Dark brown red crystels (haemin crystels) are seen under microscope.
The haemin crystal experiment is commonly used to demonstrate the power of self-organization in biological systems, specifically in the formation of heme molecules. It shows how simple molecules can come together under the right conditions to form complex structures, providing insights into biological processes such as protein folding and assembly. Additionally, studying haemin crystal formation can provide valuable information for understanding diseases related to heme metabolism.
Ghost Crystals are crystals of crosslinked polyacrylamide.
NO CRYSTALS are not living!!!!!!!!!!!!!!!!!
Granite with larger crystals, basalt with smaller crystals.
Yes. Salts can form crystals (salt crystals).
you should talk about how crystals are formed and what type of crystals there are
