Macromolecules made mainly from carbon, hydrogen, and oxygen atoms; includes fats; used for long-term storage of energy and carbon, and for building structure in the cell membranes; fatty acids and glycerol make up the simple fats most common in our diets
Lipids containing a glycerol molecule attached to three fatty acid chains; chemical form in which most fats exist in food and in the body
A lipid made from fatty acids that have at least one double bond between carbon atoms; tend to be oily liquids at room temperature; found in plants
a lipid made from fatty acids that have no double bonds between carbon atoms; tend to be solid at room temperature; found in animals
A lipid made of a phosphate group and two fatty acids; consists of a hydrophilic polar head and two non-polar hydrophobic tails; forms cell membranes.
Many of this type of lipid serve as chemical messengers or as parts of the cell membrane; examples include cholesterol, testosterone, and estrogen
Macromolecule that contains carbon, hydrogen, oxygen, and nitrogen; needed by the body for growth, repair, and to make up enzymes; a polymer made of amino acids
Compounds with an amino group (-NH₂) on one end and a carboxyl group (-COOH) on the other end; the monomers that make up a protein
Polymers assembled from individual nucleotides; used to store and transmit hereditary, or genetic, information; the two kinds of nucleic acids are ribonucleic acid (RNA) and deoxyribonucleic acid (DNA)
Monomer that makes up nucleic acids; consists of three parts: a 5-carbon sugar, a phosphate group, and a nitrogenous base
Forms the genes; in eukaryotic cells it is found in the cell nucleus and mitochondria; codes for proteins.
Works with DNA to carry out instructions of the genetic code; carries the code for a protein from the nucleus to the ribosomes; found in the nucleus, cytoplasm, and ribosomes.
Small particle of RNA and protein that produces protein following instructions from the nucleus.
