A good program of animal nutrition should include intakes of amino acids to form proteins, carbohydrates, fatty acids to form lipids, minerals, vitamins, and good quality water.
Dietary supplementation with nutrients such as zinc and linoleic acid my help improve important metabolic pathways.
The major categories of biological molecules are:
Lipids:
Lipids are important for building cell membranes and energy storage. They are composed of fatty acids. Examples: fats, phospholipids, steroids, hormones, certain vitamins
Carbohydrates:
Carbohydrates are needed for energy, energy storage, and as building materials for cells. Carbohydrates are composed of units of sugar. Examples: glucose, cellulose, starch, glycogen
Nucleic Acids:
Nucleic acids store genetic material in the cell and are composed of nucleotides. Examples: DNA, RNA
Proteins:
Proteins make up many of the structural components of the body and are important in regulating many biological processes. Proteins are composed of amino acids. Examples: trypsin, myosin, tubulin
