CARBOHYDRATE

• Carbohydrates are organic compounds composed of carbon, hydrogen, and oxygen in a ratio of one carbon atom to two hydrogen atoms to one oxygen atom.

Carbohydrates have a primary energy source for cells; provide quick energy and structural support of plant and fungi cell walls.
Examples: polysaccharide and disaccharide

LIPIDS

• Lipids are large, non-polar organic molecules. They do not dissolve in water. Lipids include triglycerides, phospholipids, steroids, waxes, and pigments.
• Lipid molecules have a higher ratio of carbon and hydrogen atoms to oxygen atoms than carbohydrates have.

Lipids store more energy.
Examples: phosphate, thymine, adenine

PROTEIN

• Proteins are organic compounds composed mainly of carbon, hydrogen, oxygen, and nitrogen. Like most of the other biological macromolecules, proteins are formed from the linkage of monomers called amino acids.
• There are more than 20 amino acids.
• Primary, secondary, tertiary, quaternary are proteins structure.

RNA protein molecules containing hundreds carboxyl amino acids. Their type of boning is peptide. They also have six functions, storage, transport, regulatory, movement, structural, enzymes. Examples: hormones, me brains and muscle

NUCLEIC ACIDS

• Nucleic acids are very large and complex organic molecules that store and transfer important information in the cell. There are two major types of nucleic acids: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

Both DNA and RNA are polymers, composed of thousands of linked monomers called nucleotides. Each nucleotide is made of three main components: a phosphate group, a five-carbon sugar, and a ring-shaped nitrogenous base.
Examples: DNA AND RNA
