What are Schiff bases?
Schiff Bases are a compounds with functional groups which contain carbon-nitrogen.
Is Heme iron absorbed better than nonheme iron?
Heme iron is much more absorbable than non-heme iron. Since the iron inanimal-based foods is about 40% heme iron and 60% non-heme iron, animal-basedfoods are good sources of absorbable iron. In contrast, all of the iron found in plantbasedfoods is non-heme iron. Meat, fish, and poultry also contain a special meatfactor that enhances the absorption of non-heme iron. Vitamin C (or ascorbic acid)also enhances the absorption of non-heme iron.
What are the organic macromolecules that contain nitrogen?
Proteins and nucleic acids are organic macromolecules that contain nitrogen.
Does Silicon contain nitrogen?
No. Silicon and nitrogen are elements. One element cannot contain another.
What atom is found in proteins but not in carbohydrates and lipids?
Nitrogen. Carbohydrates and fats contain carbon, hydrogen, and oxygen, but proteins contain carbon, hydrogen, oxygen, and nitrogen.
What elements make up proteins?
Carbon, hydrogen, nitrogen, oxygen, and (often) sulfur. All amino acids contain the first four; cysteine and methionine contain sulfur as well. Some proteins have "cofactors" or other unusual groups which can contain just about anything... for example, the protein hemoglobin contains a heme group, which has iron at its center.
What does the hemoglobin in blood contain?
Hemoglobin is made up of heme and globular protein. The heme contains iron inside a ring of carbon, hydrogen, nitrogen and oxygen molecules. The protein chains are complex helical structures.
What organic groups contain nitrogen atoms?
Proteins.
Do mussels contain heme iron?
Heme iron comes from animal sources, while non-heme iron comes from plant sources, so I believe that because mussels are animals, mussels therefore do contain heme iron. Fish also contains heme iron.
Does carbonyl groups contain nitrogen?
no,carbonyl group consist of carbon and oxygen
What does heme-negative stool mean?
Referring to stool that does not appear to contain the heme commonly associated with colorectal CA;
What are Schiff bases?
Schiff Bases are a compounds with functional groups which contain carbon-nitrogen.
Do lipids have a nitrogen base?
No. Lipids are composed of a "backbone" of glycerol and three carboxylic acid groups of varying length. Both glycerol and carboxylic acids contain only the elements carbon, hydrogen and oxygen.
Does nitrogen contain air?
Nitrogen doesn't contain air, but the air contains Nitrogen.
Does soil contain nitrogen?
Yes, soil does contain nitrogen.
Why do you bone cells and red blood cells have fewer mitochondria?
Red blood cells do not contain mitochondria, they are designed to deliver O2 via their complex heme centers & thus contain no nucleus/organelles, maximizing space for this job. Red blood cells arise from bone marrow stem cells & only circulate, carrying O2 for about 120 days before the spleen recycles their heme groups.
What element is present in protein that was not present in carbohydrates?
Proteins contain nitrogen, which is not present in carbohydrates.
