Which amino acids are aliphatic?

Aliphatic R groups are nonpolar and hydrophobic. Hydrophobicity increases with increasing number of C atoms in the hydrocarbon chain. Although these amino acids prefer to remain inside protein molecules, alanine and glycine are ambivalent, meaning that they can be inside or outside the protein molecule.

In this manner, what are the 20 types of amino acids?

20 Kinds of Amino Acids
  • Valine, Leucine & Isoleucine.
  • Alanine.
  • Arginine.
  • Glutamine.
  • Lysine.
  • Aspartic acid.
  • Glutamic Acid.
  • Proline.

Which amino acids are acidic?

There are three amino acids that have basic side chains at neutral pH. These are arginine (Arg), lysine (Lys), and histidine (His). Their side chains contain nitrogen and resemble ammonia, which is a base. Their pKa's are high enough that they tend to bind protons, gaining a positive charge in the process.

Which amino acids get phosphorylated?

Phosphorylation can occur on serine, threonine and tyrosine side chains (often called 'residues') through phosphoester bond formation, on histidine, lysine and arginine through phosphoramidate bonds, and on aspartic acid and glutamic acid through mixed anhydride linkages.
