What are the five chemical properties of amino acids?

Amino Acids

• Each amino acid contains a central C atom, an amino group (NH2), a carboxyl group (COOH), and a specific R group.
• The R group determines the characteristics (size, polarity, and pH) for each type of amino acid.

What are the characteristics and properties of amino acids?

Characteristics of amino acids:

All amino acids have at least one acidic carboxylic acid (-COOH) group and one basic amino (-NH2) group. Amino acids are colorless, crystalline solid. They are soluble in water and insoluble in organic solvent. Only L- form of amino acids are found in Proteins in human body.

What are three properties used to classify amino acids?

Nonpolar, polar, and electrically charged are the three properties of side chains used to classify amino acids.

What are functions of amino acids?

Amino acids, often referred to as the building blocks of proteins, are compounds that play many critical roles in your body. They're needed for vital processes like the building of proteins and synthesis of hormones and neurotransmitters.

What are the basic amino acids?

There are three amino acids that have basic side chains at neutral pH. These are arginine (Arg), lysine (Lys), and histidine (His). Their side chains contain nitrogen and resemble ammonia, which is a base. Their pKa's are high enough that they tend to bind protons, gaining a positive charge in the process.

What are the special amino acids?

Special amino acids are of specific interest with regard to growth and development, metabolism, and protection from environmental chemicals, as well as a variety of diseases. They include arginine, the branched-chain amino acids (BCAAs), glutamine, lysine, methionine, cysteine, and taurine.

How are amino acids held together?

Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid.

What makes each amino acid unique?

The side groups are what make each amino acid different from the others. Of the 20 side groups used to make proteins, there are two main groups: polar and non-polar. These names refer to the way the side groups, sometimes called "R" groups, interact with the environment.

How do you classify amino acids?

Amino acids can be classified based on the characteristics of their distinctive side chains as nonpolar, polar but uncharged, negatively charged, or positively charged. The amino acids found in proteins are L-amino acids.

How can you tell if an amino acid is acidic or basic?

Since an amino acid has both an amine and acid group which have been neutralized in the zwitterion, the amino acid is neutral unless there is an extra acid or base on the side chain. If neither is present then then the whole amino acid is neutral.

How are the 20 amino acids classified?

Below are the names of the 20 amino acids. Each amino acid has a three letter designation as well as a single letter designation. The amino acids are sorted in eight groups aliphatic, organic acid, amide, organic base, sulfur containing, alcohol containing, imine, and aromatic.
