What is the basic structure of a triglyceride quizlet?

What is the basic structure of a triglyceride quizlet?

What is the structure of a triglyceride? One glycerol molecule joined to three fatty acid molecules by three ester bonds.

What is the structure of triglycerides?

Triglycerides are lipid compounds composed of a glycerol esterified to 3 fatty acid chains of varying length and composition. These fatty acid chains can be saturated or unsaturated, and the chemical composition of each chain is different.

What is the structure and function of a triglyceride?

Triglycerides consist of a glycerol “backbone” along with three fatty acids bonded to the backbone in an ester linkage. Glycerol is a three-carbon molecule, C(H2)OH-C(H)OH-C(H2)OH. When one of its hydroxyl groups (-OH) loses a hydrogen, a fatty acid can bind to the oxygen in its place, creating a C-O-C (ester) bond.

What is triacylglycerol structure?

Triacylglycerols are formed by linking fatty acids with an ester linkage to three alcohol groups in glycerol. Triacylglycerols are the form in which fat energy is stored in adipose tissue. Triacylglycerols are sometimes referred to as triglycerides.

What type of reaction breaks down triglycerides?

Lipolysis. To obtain energy from fat, triglycerides must first be broken down by hydrolysis into their two principal components, fatty acids and glycerol. This process, called lipolysis, takes place in the cytoplasm. The resulting fatty acids are oxidized by β-oxidation into acetyl CoA, which is used by the Krebs cycle …

What is the functional group that is formed during formation of a triglyceride quizlet?

Fats, also known as triacylglycerols, contain three fatty acids attached to a glycerol backbone. Each carboxyl functional group on the fatty acids is joined to one of the three hydroxyl functional groups on the glycerol by an ester linkage.

What are the 7 main groups of triglycerides?

Triglyceride

  • Saturated fat.
  • Unsaturated fat. Monounsaturated fat. ω−7. ω−9. Polyunsaturated fat. ω−3. ω−6. Trans fat. Interesterified fat.

What is the primary function of triglycerides?

Triglycerides provide your body with energy, but their main function is to store energy for later use. The food you eat contains calories in the form of carbohydrates, protein and fat.

What are the 4 parts of a triglyceride?

Triglycerides are the predominant component of most food fats and oils. The minor components include mono- and diglycerides, free fatty acids, phosphatides, sterols, fatty alcohols, fat-soluble vitamins, and other substances. A triglyceride is composed of glycerol and three fatty acids.

What makes up the structure of a triglyceride?

Fatty Acids (FA) are most often found in the diet and in the body attached to another molecule to form a new structure called a Triglyceride or TG (sometimes called triacylglyceride or TAG). Glycerol serves as the “backbone” for TG molecules. Glycerol is made of 3-carbon molecules each with a hydroxyl group ( -OH).

What is the structure of a glycerol molecule?

Glycerol is a three-carbon molecule with three hydroxyl groups on them. These hydroxyl groups are the site of an ester reaction with three fatty acid molecules. The fatty acids can be different types, and the fatty acid structure defines the type of triglyceride. The fatty acids are long chains of carbons with bonded hydrogens.

What’s the difference between liquid and solid triglycerides?

At normal temperatures these fats are solid called “fats”, whereas in liquid form they are called “oils”. Fatty acids present within triglycerides can be of varying sizes, but16, 18, 20 carbons are the most commonly present in triglyceride molecule.

How are triglycerides absorbed in the human body?

The breakage of triglyceride molecule is necessary as body cannot use triglycerides as such in its original form. The fatty acids, monoglycerides (one glycerol, one fatty acid) and some diglycerides, all form after breakage of triglycerides, can be absorbed by the duodenum and utilized in body.
