  Definition: Lipids are a broad group of naturally-occurring molecules which includes fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E and K), monoglycerides, diglycerides, phospholipids, and others.
  The whole of lipids is the lipidome.
  Lipids are broadly defined as any fat-soluble (lipophilic), naturally-occurring molecule. Lipids are usually defined as hydrophobic or amphipathic biological molecules that will dissolve in organic solvents such as benzene or (...)

• human proteins
  4 June 2003

  Proteins are made of amino acids arranged in a linear chain and joined together by peptide bonds.
  Many proteins are the enzymes that catalyze the chemical reactions in metabolism. Other proteins have structural or mechanical functions, such as the proteins that form the cytoskeleton, a system of scaffolding that maintains the cell shape.
  Proteins are also important in cell signaling, immune responses, cell adhesion, active transport across membranes, and the cell cycle.

  Definition: Cytosine is a pyrimidine base (nitrogenous base) and constituent of nucleotides and as such one member of the base pair G-C (guanine and cytosine).
  Cytosine is one of the 5 main nucleobases used in storing and transporting genetic information within a cell in the nucleic acids DNA and RNA.
  Cytosine is a pyrimidine derivative, with a heterocyclic aromatic ring and two substituents attached (an amine group at position 4 and a keto group at position 2).
