What amino acid will yield a positive result with lead acetate test?
Cystein and methionie
What is nitrogen a key element for the formation of?
Amino Acids
Why does alanine have a high melting point?
Because of the amine group present and the carboxylic acid present both in the amino acid this makes it polar thus leading to a high melting point
Is rice a compound mixture or an element?
Yes rice is a compound because if rice was not not a compound, but and element, it would be on the periodic table.
What is the constituent element of protein?
Protein is composed of amino acids, which are in turn made up of mostly carbon, hydrogen, oxygen, and nitrogen. A few amino acids also contain sulfur: both Cysteine and Methionine. Thus, proteins containing these amino acids would be made up of very small amounts of sulfur, in addition to the more common elements listed above. In short-- The five chemical elements of protein are carbon, sulfur, hydrogen, oxygen, and nitrogen, with carbon being the most abundant.
What element in the amino acid is detected to be present in the lead acetate test?
Arginine.
What chemical element is present in proteins and nucleic acids but not sugars and fats?
Phosphorus complexes are present in proteins but is not present in sugars or fats..
Is oxygen present in protein but not in fats?
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
Will Alanine give a negative Biuret test?
Because solutions with "free" amino acids don't have peptide bonds and peptide bonds need to be present in order for the test to be positive.
What amino acid will yield a positive result with lead acetate test?
Cystein and methionie
The amino group of an amino acid is based on which element?
nitrogin
Are there any amino acids in the periodic table?
An amino acid is a molcule, a collection of atoms including hydrogen, carbon and nitrogen amonst others. The periodic table is a table of the elements so the element sthat make up amino acids a present in it but not the molecules.
What amino acid is not present in glucose?
No amino acid is present in glucose. Glucose is a carbohydrate, not a protein.
What end arrangements of atoms is present in amino acids that also present in fatty acids?
hydrogen and amino acids.
What end arrangement of atoms is present in amino acids that is also present in fatty acids?
hydrogen and amino acids.
What is an element of Dna that is not found in amino acids?
That element would be phosphorus.
What element isn't present in lipids or carbohydrates but is in proteins?
Nitrogen. Look at the structure of a peptide bond which connects each amino acid together. That is where the nitrogen is located
