What characteristic of a fat determines whether it is unsaturated?

At the molecular level, unsaturated fats contain carbon-to-carbon double bonds, and their configuration ultimately determines their health properties in the human diet.

What are the different types of biomolecule describe each structure?

biomolecule, also called biological molecule, any of numerous substances that are produced by cells and living organisms. Biomolecules have a wide range of sizes and structures and perform a vast array of functions. The four major types of biomolecules are carbohydrates, lipids, nucleic acids, and proteins.

What are the four major categories of macromolecules?

11.1 Introduction: The Four Major Macromolecules These are the carbohydrates, lipids (or fats), proteins, and nucleic acids.

Which types of dietary fats can increase blood LDL concentrations?

Dietary fat, especially saturated and trans fats, may raise blood levels of total and LDL cholesterol.

How are saturated and unsaturated fats different in their structure and function?

If there are only single bonds between neighboring carbons in the hydrocarbon chain, a fatty acid is said to be saturated. When the hydrocarbon chain has a double bond, the fatty acid is said to be unsaturated, as it now has fewer hydrogens.

What is the difference between saturated fat and unsaturated fat?

The difference between saturated and unsaturated fat lies in the number of double bonds in the fatty acid chain. Saturated fats tend to be solid at room temperature and from animal sources, while unsaturated fats are usually liquid and from plant sources.

What are the four types of biological molecules describe their basic structures and functions?

Four Major Types of Biomolecules

  • Carbohydrates. Carbohydrates are a vital part of a healthy diet.
  • Proteins. Proteins are unbranched polymers of amino acid residues.
  • Nucleic Acids. Nucleic acids are macromolecules present in cells and viruses, and they are involved in the storage and transfer of genetic information.
  • Lipids.

What are the 4 biomolecules and their monomers?

As we’ve learned, there are four major classes of biological macromolecules:

  • Proteins (polymers of amino acids)
  • Carbohydrates (polymers of sugars)
  • Lipids (polymers of lipid monomers)
  • Nucleic acids (DNA and RNA; polymers of nucleotides)

What are the 4 main macromolecules and their functions?

Nucleic acids: Stores and transfers info.

  • Carbohydrates; Store energy, provide fuel, and build structure in body, main source of energy, structure of plant cell wall.
  • Lipid: Insulator and stores fat and energy.
  • Protein: Provide structural support,transport, enzymes, movement, defense.

    • Are all biological macromolecules polymers?

    Biological macromolecules play a critical role in cell structure and function. Most (but not all) biological macromolecules are polymers, which are any molecules constructed by linking together many smaller molecules, called monomers.

    Does unsaturated fat increase LDL?

    Both types offer health benefits. Eating polyunsaturated fats in place of saturated fats or highly refined carbohydrates reduces harmful LDL cholesterol and improves the cholesterol profile. It also lowers triglycerides.

    Do saturated fats raise LDL?

    Because saturated fat tends to raise low-density lipoprotein (LDL) cholesterol levels in the blood. High cholesterol levels can increase your risk of heart disease and stroke. Saturated fat occurs naturally in red meat and dairy products.
