Which component of an amino acid determines its unique qualities?

Which component of an amino acid determines its unique qualities?

The R group determines the characteristics (size, polarity, and pH) for each type of amino acid. Peptide bonds form between the carboxyl group of one amino acid and the amino group of another through dehydration synthesis. A chain of amino acids is a polypeptide.

Which of the following is responsible for making every amino acid unique?

exam 1

Question Answer
the part of the atom that determines how the atom behaves chemically is the electron
responsible for making every amino acid unique.. “R” group
the DNA of prokaryotic cells is found in the nucleoid region
an amino acid that is small enough to fit into tight corners of proteins molecules is glycine

What three structural groups shown do all amino acids have in common?

Amino acids are the monomers that make up proteins. Each amino acid has the same fundamental structure, which consists of a central carbon atom, also known as the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom.

How many amino acids are present in milk?

9

Which amino acid is absent in milk?

The “first-limiting” amino acid of any diet will depend upon the amino acid profile of the ingredients in the ration. For dairy cows, it is usually lysine or methionine. Arginine is also a concern. Three different branched-chain amino acids can also become limiting (valine, isoleucine, and leucine).

What is the first limiting amino acid?

Lysine is the first limiting amino acid in many high-protein foods.

Which protein is present in milk?

Casein
