Amino acids are the building blocks of proteins with different properties.

• There are 20 standard amino acids in proteins

• Amino acids can be classified based on their side chain properties: nonpolar, polar, acidic, and basic

• Nonpolar amino acids are hydrophobic, while polar amino acids are hydrophilic

• Acidic amino acids have a negative charge at physiological pH, while basic amino acids have a positive charge

• Examples: Glycine (nonpolar), Serine (polar), Glutamic acid (acidic), Lys...read more
