Biomolecules

Biomolecules: molecules made by organisms that are essential for performing life functions.

There are four types of biomolecules: carbohydrates, proteins, lipids, and nucleic acids.

Carbohydrate: Consists of CHO. Storage of energy, structural component in plants.

Examples of Carbohydrate: starch cellulose.

Types of Lipids: Triglycerides, Phospholipids, and Steroids.

Triglycerides: function as long term energy source.

Phospholipids: Hydrophobic tails and hydrophilic heads. Primary structure of cell membranes.

Steroids: some act as hormones. Cholesterol is a steroid that is the structural component of animal cell membranes.

Lipid: Consists of CHO. Long-term energy storage, structural component of membranes. Hydrophobic.

Examples of Lipid: fat, phospholipids.

Some characteristics of the four types of biomolecules: Include DNA/RNA, oils and fats, store/utilize genetic information, provide stored energy for quick access, enzymes, main component of bread and pasta, function in long term storage, stored in plants as starch.

Protein: Structural component of metabolic regulator.

Examples of Protein: Actin, Hemoglobin.

Nucleic Acid: Storage and transfer of genetic code

Examples of Nucleic Acid: DNA, RNA.
