13.1: Amino Acids – Chemistry LibreTexts
The following rules (along with two exceptions) can help you classify amino acids as nonpolar, polar acidic (sometimes called acidic), polar basic (sometimes called basic), or polar neutral. We will look at two exceptions but note that the transition from nonpolar to polar neutral is a gradual transition (like the colors of a rainbow) so you …
13.2: Peptides
Peptides. A peptide is a combination of amino acids in which the amine group of one amino acid has undergone a reaction with the carboxyl group of another amino acid.The reaction is a condensation reaction, forming an amide group (left( ce{CO-N} right)), shown below. Figure (PageIndex{1}): Amino acids undergo condensation to form a molecule called a dipeptide.

Amino Acids: Structure, Classification and Function – ThoughtCo
Based on the variable group, amino acids can be classified into four categories: nonpolar, polar, negatively charged, and positively charged. Of the set of twenty amino acids, eleven can be made naturally by the body and are termed nonessential amino acids. Amino acids that can not be naturally made by the body are called essential .

The properties of the side chain determine an amino acid’s chemical behavior (that is, whether it is considered acidic, basic, polar, or nonpolar). For example, amino acids such as valine and leucine are nonpolar and hydrophobic, while amino acids like serine and glutamine have hydrophilic side chains and are .

Amino Acid Structure. Amino acids are the monomers that make up proteins. Each amino acid has the same core 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 a hydrogen atom. Every amino acid also has another atom or group of atoms bonded to the …

12 sept. 2022The side chains of amino acids are often called R groups. They can be polar, nonpolar, or charged, and this gives rise to amino acids with varying physical properties. The polar and charged amino acids are hydrophilic and can dissolve in water, whereas the nonpolar amino acids are hydrophobic and do not dissolve in water. lesoutrali bot
