What are some of the main chemical characteristics of 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 is the chemical name of valine?
Valine
Valine/IUPAC ID
What do leucine isoleucine and valine have in common?
Leucine, isoleucine, and valine (another amino acid) are grouped together as branched chain amino acids or BCAAs. All BCAAs are essential to human life. They are needed for the physiological response to stress, in energy production, and particularly for the normal metabolism and health of muscle.
Which of the following terms best describes the side chain of valine?
According to the structure of valine, the side chain of valine is basically a non-polar isopropyl group. Hence, the correct option is (e) non-polar.
Is valine acidic or basic?
Acidic amino acids (which have negatively charged side chains at neutral pH) have quite low examples (Table 18.1. 1)….18.1: Reactions of Amino Acids.
| Amino Acid | Classification | pI |
|---|---|---|
| valine | nonpolar | 6.0 |
| serine | polar, uncharged | 5.7 |
| threonine | polar, uncharged | 6.5 |
| arginine | positively charged (basic) | 10.8 |
Is valine soluble in water?

What are the physical characteristics of amino acids?
Amino acids are colorless, crystalline solid. Solubility: They are soluble in water, slightly soluble in alcohol and dissolve with difficulty in methanol, ethanol, and propanol. R-group of amino acids and pH of the solvent play important role in solubility. On heating to high temperatures, they decompose.
