which of the following is a function of fats (lipids) course hero

What is the function of lipids?

A lipid is a hydrophobic (does not interact with water molecules) macromolecule that may provide storage, structure, or nutrients in organisms. Lipids can be categorized into three different types, each with its own important functions. Triglycerides are molecules better known as fats.

What are the 3 types of lipids?

Lipids are insoluble in water and can be divided into three categories: triglycerides, phospholipids, and steroids. A lipid is a hydrophobic (does not interact with water molecules) macromolecule that may provide storage, structure, or nutrients in organisms.

What is the function of cholesterol in the cell membrane?

Cholesterol is an important component in the cell membrane, where it helps to stabilize the structure and control the flow of water in and out of the cell. Cholesterol is also the precursor to steroid hormones, including most of the sex hormones, as well as vitamin D and bile salts.

Can the human body make fats from carbohydrates and protein?

While some fatty acids are essential, the human body can also make fats from carbohydrate and protein. Which of the following is NOT one of the three main categories of lipids? Nice work! You just studied 53 terms!

How many fatty acids are in a triglyceride?

A triglyceride consists of three fatty acids and one glycerol. The fatty acids may be saturated (no double bonds) or unsaturated (at least one double bond). This triglyceride molecule will be metabolized into a molecule of glycerol and three fatty acids. Two of the fatty acids are saturated and one is not.

What macromolecules do not interact with water molecules?

A lipid is a hydrophobic (does not interact with water molecules) macromolecule that may provide storage, structure, or nutrients in organisms. Lipids can be categorized into three different types, each with its own important functions.

Is cholesterol a nutrient?

Cholesterol is often thought of negatively in association with heart disease, but it is a necessary nutrient for cell function and overall health. The cell membrane is composed of a bilayer of phospholipids with their hydrophobic tails facing one another. Cholesterol's nonpolar end is located next to the lipid tails while its polar end is near the polar phosphate. This arrangement lends strength and fluidity to the cell membrane.
