Glycine (Gly) H-. AMINO ACIDS have both an acidic group, in the carboxylic acid, and a basic group, in the amine. Under physiological aqueous conditions a proton transfer from the acid to the base occurs, forming a dipolar ion or zwitterion, because the carboxylic acid is a much stronger acid than is the ammonium ion.

A base is an acid's chemical opposite.. A base is a substance that will accept the acid's hydrogen atom.

Acids can be dangerous: The holes in the paper were made by a solution with 98% sulfuric acid. An acid is a substance that can donate a hydrogen ion (H+) (generally speaking, this will be a proton) to another substance. Acids have a pH less than 7.0. A chemical can donate a proton if the hydrogen atom is attached to an electronegative atom like oxygen, nitrogen, or chlorine.

Amino acid structure and its classification. An amino acid contains both a carboxylic group and an amino group. Amino acids that have an amino group bonded directly to the alpha-carbon are referred to as alpha amino acids. The simplest representation of an alpha amino acid is shown below.

An AMINO ACID is by definition an organic compound containing an amine group and a carboxylic acid group in the same molecule. While there are many forms of amino acids, all of the important amino acids found in living organisms are alpha-amino acids.

Image of an amino acid structure. Every alpha amino acid has a carbon atom, called an alpha carbon, ; bonded to a carboxylic acid, , group; an amino, , group; a hydrogen atom; and an R group that is unique for every amino acid.

For most reactions, however, the acids and bases are not present in equal amounts, and this imbalance is what allows a chemical reaction to occur. Every acid has a conjugate base formed by removing the acid's proton. Hydrochloric acid (HCl), for example, is an acid and its conjugate base is a chlorine anion, or Cl-.

There is very little information to be found about amino acids. Often what is written sounds like it's in a different language. Not being a biochemist myself, I will attempt to explain amino acids in relatively simple terms and try to convey the little knowledge that I have. Amino (uh MEE noh) acids are the acids that make up all proteins. Next to water, protein makes up the greatest portion of our body weight. Muscles, ligaments, organs, glands, nails, hair, blood, lymphatic fluid, the central nervous system and the brain is mostly made of various proteins.

Alpha amino acids have the -COOH and -NH2 groups both attached to the same carbon atom, called the alpha carbon atom. The simplest amino acid, which is the molecule glycine, H2NCH2COOH, contains no asymmetric carbon atoms (tetrahedral carbon atoms with four different groups attached). All of the other amino acids do contain such a carbon atom and are therefore optically active.

Chemistry of amino acids and protein structure. Proteins are large, complex molecules that are critical for the normal functioning of the human body. They are essential for the structure, function, and regulation of the body’s tissues and organs.

what is the simplest amino acid?
Glycine is the simplest amino acid. The molecule glycine is the simplest amino acid which contains no asymmetric carbon atoms.
