[Chemistry Class Notes] on Amino Acid Formula Pdf for Exam

Amino acids are organic compounds that comprise functional groups: of amino, i.e., – NH2, and carboxyl, i.e., – COOH, along with a side chain (R or alkyl group) specific to each amino acid group. So, the key elements in an amino acid formula are carbon (C), hydrogen (H), oxygen (O), and nitrogen (N). Besides this, the side chains of amino acids are attached with other elements.

Amino acids have a specific amino formula, which we will discuss on this page, along with the structural formula of basic amino acids.

Amino Acid Molecular Formula 

Amino Acid formula is also known as the Saltpeter formula or Nitrate of potash formula.

The amino acid molecular formula is H2NCHRCOOH in most cases, where R is an organic substituent known as a “side chain.” 

Amino Acid Structure

Below is the structural formula of basic amino acid along with the labelling of each group:

      

In the above structural formula of basic amino acid,  an amino acid group formula consists of a central carbon atom, also known as the alpha (α) carbon. This central carbon atom is attached to an amino group (NH2), a carboxyl group (COOH), and a hydrogen atom.

Also, all the amino acids differ from each other in the particular chemical structure of the R (alkyl) group.

Amino Group Formula

Amino group formula is divided into the following three categories:

• Essential amino acids group formulas

• Conditional amino acid group formulas

• Non-essential amino acid group formulas

Now, let’s have a look at the amino acid group formulas one-by-one:

Essential Amino Acid Group Formulas

Conditional Amino Acid Group Formulas

Non-Essential Amino Acid Group Formulas

Amino Acid Baby Formula

Amino acid baby formula, for instance, Neocate, is milk-free. It is made up of non-allergenic amino acids, which are the building blocks of protein, which means that there is little chance of a child being exposed to an allergic reaction to them, however, a typical allergic reaction is a reaction to protein.

Amino Acid Formula Milk

Amino acid formula milk is a sort of infant milk formula produced using individual amino acids. 

It is hypoallergenic and planned for newborn children experiencing a serious allergy to milk and different gastrointestinal conditions, for instance, protein-induced enterocolitis syndrome and malabsorption syndromes.

Conclusion

The amino acid is an organic compound that comprises functional groups of amine and carboxyl along with a side chain that is specific to each amino acid. The key elements are carbon, hydrogen, nitrogen, and oxygen.
