Either nitrogen, phosphorus, chlorine or potassium... I can't tell, but hope that helps:]
Compounds made from living sources that contain carbon include carbohydrates (such as glucose and cellulose), lipids (such as fats and phospholipids), proteins (such as enzymes and antibodies), and nucleic acids (such as DNA and RNA).
Better question. What cells do not contain proteins? Proteins is from the Greek and means " first place, " so I can not think of any cell without some types of proteins.
Phosphorus complexes are present in proteins but is not present in sugars or fats..
All proteins contain carbon, oxygen, hydrogen and nitrogen. Some also contain sulphur in the amino acids Methionine and Cysteine.
All meats are mostly protein.
Proteins contain nitrogen, which is not present in carbohydrates.
All proteins contain carbon, hydrogen, nitrogen, and oxygen. Many also contain sulfur, and cofactors can have all kinds of wacky stuff in them, like iron, manganese, cobalt, you name it.
Elements are pure substances, consisting of atoms. They do not contain proteins. Proteins are molecules consisting of a chain of atoms.
Compounds made from living sources that contain carbon include carbohydrates (such as glucose and cellulose), lipids (such as fats and phospholipids), proteins (such as enzymes and antibodies), and nucleic acids (such as DNA and RNA).
The main element in protein is nitrogen. Proteins are made up of amino acids, which contain nitrogen in addition to carbon, hydrogen, and oxygen. This distinguishes proteins from carbohydrates and fats, which do not contain nitrogen.
Nitrgen. The all have the elements Carbon, Hydrogen and Oxygen in common, but on top of that, proteins ALSO contain nitrogen.
Proteins contain carbon, hydrogen, oxygen, and nitrogen.
Nitrogen is a key element. Proteins contain nitrogen and without nitrogen no protein.
All living organisms contain the element carbon. Carbon is a key component of molecules like proteins, carbohydrates, lipids, and nucleic acids that are vital for life processes.
Nitrogen is the element present in all proteins except carbohydrates and fats. Amino acids make up all proteins, and they contain the amino group NH2, except for carbohydrates and fats.?æ
Better question. What cells do not contain proteins? Proteins is from the Greek and means " first place, " so I can not think of any cell without some types of proteins.
Proteins have the most nitrogen element among the three biomolecules listed. Proteins are composed of amino acids, which contain nitrogen in their chemical structure. Both carbohydrates and lipids contain very low amounts of nitrogen in comparison.
