Carbon, Hydrogen and oxygen= presence of the three can be tested by heating a (protein preferably Casein) containing solid in a test tube over a low flame.
Nitrogen= nitrogen's presence can be tested in casein through mixture with Soda lime and heat. the confirmatory product is NH3 gas which turns red litmus paper to blue.
to test for sulfur and phosphorus perform first the fusion reaction.
Sulfur= presence is indicated by a white precipitate BaSO4 through reaction with BaCl2 in acid medium
Phosphorus= addition of ammonium molybdate in acidic solution and heat forms yellow precipitate.

What is the composition of the rough er?

Who discovered the chemical composition of proteins?
The chemical composition of proteins was first elucidated by the German chemist Emil Fischer in the late 19th century. He is credited with identifying the amino acids that make up proteins and determining their arrangement, which laid the groundwork for understanding protein structure and function. Fischer's work earned him the Nobel Prize in Chemistry in 1902.
Do protons have a positive or negative charge?
The Proton has a positive charge equal to the elementary charge. This is due to its composition of a down quark and two up quarks which have charges of -1/3 the elementary charge and +2/3 the elementary charge respectively.
Do atoms go up by one on the periodic table in proteins and neutrons?
Atoms do not change in proteins, but elements may vary depending on the composition of amino acids involved. Neutrons are not incorporated into proteins; they are subatomic particles found in the nucleus of an atom, contributing to its mass.
What are the elementary composition of proteins?
Carbon, Hydrogen, Oxygen, Nitrogen, Sulfur, Phosphorus
What is the purpose of using SDS-PAGE in analyzing DNA samples?
SDS-PAGE is used to separate and analyze proteins, not DNA. It is a technique that separates proteins based on their size and charge. This can be useful in studying protein composition and identifying specific proteins in a sample.

Whats the purpose of composition of picture?
The purpose of the composition of a picture is that it provides more information about the picture in question.
What is the composition of kinetochore?
It is made up of proteins and DNA.
What is the quark composition of a muon?
A muon does not have a quark composition as it is a type of elementary particle, not a composite particle made up of quarks. Muons are classified as leptons, which are fundamental particles that do not experience the strong nuclear force and are not composed of quarks.
