Cobalt(II) Oxygen adduct complex Inorganic 461 lab 2-29-2012 Abstract This experiment uses Co(salen) as a model compound illustrating the uptake of oxygen in hemoglobin. SalenH2 was prepared as the intermediate, and reacted with hydrated cobalt to prepare Co(salen). Using Co(salen) the oxygen up-take was tested. The synthesis of SalenH2 produced 0.65 g. The percent yield of salenH2 was 116% on the filter paper and 105% after transferring salenH2 to a vial. The melting point of salenH2, was

Synthesis and Characterization of Zn(TPP) and Cu(TPP) Complexes 1 Project Summary The overall goal of the project is to synthesize two metalloporhyrins, (Tetraphenylporphyrinato)zinc(II) and (Tetraphenylporphyrinato)copper(II). Because metalloporphyrins occur naturally in hemoglobin and chlorophyll, their study has implications in synthesizing human blood as well as utilizing its ability to convert visible light to energy. In addition to these two applications, metalloporhyrins are utilized in

Iron carries oxygen to cells, tissues and organs. Red meats, such as hamburger, are some of the best sources of heme iron. Heme iron is found only in animal-based foods, is highly bioavailable and easy for your body to utilize. Your body absorbs as much as 35 percent of the heme iron you get from meat, versus only two to 20 percent of nonheme iron from plant-based foods, according to the Office of Dietary Supplements. Adult men need eight milligrams of iron each day, while women require 18 milligrams

enough oxygen. Having a lack of red blood cells is called an ‘Iron deficiency’ the scientific name for it being anaemia. There are two types of iron in food, one being Heme iron which is found in only in animal foods, meat as 40% heme iron and 60% non- heme iron where as plants contain no heme iron at all. The other type being non-heme iron which is found mainly from plant foods such cereals, legumes, vegetables and fruit. Iron is founds in a wide variety of foods, seeing as iron can not be produced

food: “heme and non-heme iron . Heme iron, which makes up 40 percent of the iron in meat, poultry, and fish, is well absorbed. Non-heme iron, 60 percent of the iron in animal tissue and all the iron in plants (fruits, vegetables, grains, nuts) is less well absorbed” (Mangels 16). Both forms of iron are beneficial in consuming the appropriate amount of iron, but heme iron is consumed more than nonheme iron is. If one is trying to absorb more nonheme iron, they can combine nonheme iron and heme iron

Heme-group containing mammalian peroxidase enzymes possess a highly conserved structure and partake in reactions associated with the development of inflammatory diseases, defense system of the host as well as the biogenesis of hormones (Péterfi et al., 2009)(Cheng, Salerno, Cao, Pagano, & Lambeth, 2008). The heme-binding sites of peroxidase enzymes possess specific features that are preserved as well as characteristics including disulphide bonds forming between cysteine residues, a binding site for

experimental procedures that were performed by Bayry et al that allowed for this experiment to be performed. One of these procedures included treatment of an IgE antibody that is produced specifically in mice, SPE7 with heme using the technique immunoblotting to determine the polyreactivity of heme and the resulting consequences of the reaction. Immunoblotting, also known as western blotting, is a type of an assay that is specifically used for the detection and characterization of proteins1. According to Gallagher

coconut oil, soy protein, xanthan gum, and the magic ingredient “heme.” It’s often the texture, smell, and flavor of meat that carnivores crave and where most mass-produced vegetarian or vegan options fall flat. Chef Brown’s recipe for the Impossible Burger has truly changed the game when it comes to meat substitutes and he’s challenging us all to spot the difference. What the heck is “heme”? Is it safe? For those unaware, “heme” is the protein used by Chef Brown as his “magic ingredient” and

The oxyhaemoglobin dissociation curve is a simple concept that explains the pathways that oxygen travels in the blood stream. The oxyhaemoglobin dissociation curve explains how the oxygen is carried in haemoglobin molecules, which each contain four heme molecules that bind with the oxygen. The curve explains how oxygen is transferred from the blood stream into the surrounding hypoxic tissues. The oxyhaemoglobin dissociation curves relation to pulse oximetry is explained, as it gives us a better understanding

body’s red blood cells mutating them to where the hemes enzyme is nonexistent (Daempfle, 2016). The hemes job is to accumulate oxygen in the blood cells, so when it does not store the hemes the porphyrins amass causing issues. These issues or symptoms manifest as extreme hair development, hunger for blood, photosensitivity, skin abrasions, receding gum lines, and worst of all it impairs organs (Daempfle, 2016). Due to the body’s failure to produce hemes blood transfusions are required for affected individuals
