Carbohydrates, lipids, nucleic acids, and proteins

Do you know what a lipid is?

Lipids

Elements: carbon, hydrogen, and oxygen

Monomers and polymers: none

Types:Cholesterol, fatty acid, triglyceride, fatty acyls, glycerolipids, glycerophospholipids, sphingolipids, sterol lipids and prenol lipids (derived from condensation of isoprene subunits), and prenol lipids and saccharolipids (derived from condensation of ketoacyl subunits)

Functions: energy storage, structural components of cell membranes, important signaling molecules



Proteins

Where are proteins in everyday life?

Proteins

Elements: carbon, hydrogen, oxygen, nitrogen, sulfur and selenium

Monomers and polymers: amino acids and polypeptides

Types: structural, storage, hormonal, enzyme, defensive, receptor, contractile and transport

Functions: helps with growth and repair, builds body parts, provides energy, carries oxygen in the blood and fights germs



What are nucleic acids?

Nucleic Acids

Elements: adenine, guanine, cytosine, thymine, and uracil.

building blocks are made up of carbon, hydrogen, oxygen, nitrogen, and phosphorus.

Monomers and Polymers: RNA and DNA are polymers made up of nucleotides.

Types: DNA, RNA, and nucleotides.

Functions: makes up genetic information in living things.





Carbohydrates

Elements: carbon, hydrogen, and oxygen

Sub groups: monosaccharides, disaccharides, and polysaccharides

Polymers: sugars

energy sources are starch, glucose, and sucrose

Functions: give fuel to our bodies and is a raw materials for building molecules are monosaccharides. Polysaccharides are for plants and the glucose molecules join together.

Examples for disaccharides are table sugar, milk sugar, and alcohol sugar.
