Question

A researcher discovers a small molecule in muscle tissue that is rich in nitrogen, soluble in water, and lacks phosphorus. The molecule also contains carbon, hydrogen, and oxygen, in uneven ratios. The molecule must be a(n)

Answer 1

The right answer is Amino acid.

Amino acids are molecules that enter into the composition of proteins through their assembly by so-called peptide bonds.

Their name comes from the fact that they have an amine function (NH2) and a carboxylic acid function (COOH). They are distinguished by their side chain, R, which may be a simple hydrogen atom (it is glycine), or even more complex.

Answer 2

It seems that you have missed the necessary options for us to answer this question, so I had to look for it and here is the answer. When a researcher discovers a small molecule in muscle tissue that is rich in nitrogen, soluble in water, and lacks phosphorus, the molecule also contains carbon, hydrogen, and oxygen, in uneven ratios. The molecule must be an AMINO ACID. Hope this helps.
