Note: This chart only shows those amino acids for which the human genetic code directly codes for. Selenocysteine is often referred to as the 21st amino acid, but is encoded in a special manner.

Amino acids with a non-polar (hydrophobic) side chain: glycine, alanine, valine, leucine, isoleucine, proline, phenylalanine, tryptophan and methionine. All of them are less soluble in water than the …

We assimilate these compounds as proteins (amino acids) in our diets. Cannot be synthesized de novo, hence, must be supplied in the diet. Amino acids are classified as glucogenic, ketogenic, or both …

Amino acids can undergo a condensation reaction which results in the formation of a bigger, peptide molecule! As noted by the name, a resulting water molecule also emerges as a product of the …

In order to understand acid-base properties of proteins and their behavior as polyionic macromolecules, we will begin by investigating the properties of their constituent amino acids.

Amino Acids: Classification • The 20 amino acids found in proteins can be placed in five families based on the physical and chemical properties of their R groups:

The Chemical Nature of Amino Acids des are polymers of α-amino acids. There are 20 α-amino acids that make-up ll proteins of biological interest. The α-amino acids in peptides and proteins consist of a …
