how are amino acids different from each other?

Something Called Side Groups 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.

To form polypeptides and proteins, amino acids are joined together by peptide bonds, in which the amino or NH2 of one amino acid bonds to the carboxyl (acid) or COOH group of another amino acid.
40121
When connected together by a series of peptide bonds, amino acids form a polypeptide, another word for protein. The polypeptide will then fold into a specific conformation depending on the interactions (dashed lines) between its amino acid side chains.

Both peptides and proteins are made up of strings of the body's basic building blocks – amino acids – and held together by peptide bonds. In basic terms, the difference is that peptides are made up of smaller chains of amino acids than proteins.

['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.']

Among the 20 standard amino acids, 19 amino acids are alpha-amino acids, whereas proline is imino acid. Amino acids yield various product on oxidation. Fatty acids are formed by hydrolysis of fats like triacyl glycerol or TGs. Each fatty acid molecule has a carboxyl group attached with an aliphatic chain.
1369544
All amino acids have a carboxyl group and an amino group bonded to the same carbon atom (the α carbon). ... Some 300 additional amino acids have been found in cells but they are not constituents of proteins. These amino acids are commonly known as uncommon amino acids.

Amino acids. Amino acids are the monomers that make up proteins. Specifically, a protein is made up of one or more linear chains of amino acids, each of which is called a polypeptide.
1416499
The main difference between amino acids and fatty acids is that the amino acids are the building blocks of proteins whereas the three fatty acids bound to a glycerol and form a triglyceride, which is the main constituent of fat. ... Amino acids and fatty acids are two types of building blocks of macromolecules of the body.
868115
All amino acids have the alpha carbon bonded to a hydrogen atom, carboxyl group, and amino group. The "R" group varies among amino acids and determines the differences between these protein monomers.
1262782
Amino acids are the structural units (monomers) that make up proteins. They join together to form short polymer chains called peptides or longer chains called either polypeptides or proteins. ... Twenty-two amino acids are naturally incorporated into polypeptides and are called proteinogenic or natural amino acids.
677398
Amino acids are organic compounds that contain amine (-NH2) and carboxyl (-COOH) functional groups, along with a side chain (R group) specific to each amino acid.
480616
Amino acids are the building blocks of proteins. All amino acids have an identical core structure consisting of an alpha-carbon, carboxyl group, amino group and R-group (sidechain). A linear chain of amino acids is a polypeptide.
1366334
An amino acid is an organic molecule that is made up of a basic amino group (−NH2), an acidic carboxyl group (−COOH), and an organic R group (or side chain) that is unique to each amino acid. The term amino acid is short for α-amino [alpha-amino] carboxylic acid. ... Amino acids function as the building blocks of proteins.
1264859
There are 20 different amino acids which make up proteins. Each amino acid consists of a central carbon. The central carbon is bonded to an amine group ( NH2 ), a carboxyl group (COOH), a hydrogen atom and an R group.
356471
Amino acids are organic compounds that combine to form proteins. Amino acids and proteins are the building blocks of life. When proteins are digested or broken down, amino acids are left.
380476
There are 20 amino acids that make up proteins and all have the same basic structure, differing only in the R-group or side chain they have. The simplest, and smallest, amino acid is glycine for which the R-group is a hydrogen (H).
