The answer is B) amine group. Proteins are made up of many amino acid units. The amino acid units have an amino group as part of the general…

Where are triglycerides found in food?

What are triglycerides? Triglycerides are fats from the food we eat that are carried in the blood. Most of the fats we eat including butter margarines and oils are in triglyceride form. Excess calories alcohol or sugar in the body turn into triglycerides and are stored in fat cells throughout the body.

What are stored triglycerides called?

The intestinal cell reforms the triglycerides and stores them in particles called chymomicrons which consists predominately of triglycerides as well as a bit of protein cholesterol fat-soluble vitamins phospholipids and other molecules.

Where in the body do we find the greatest storage of potential energy?

Where in the body do we find the greatest storage of potential energy to fuel long-term activities? Muscle tissue contains enough creatine phosphate (CP) to sustain physical activity for up to 10 to 15 minutes.

Where are phospholipids found in the body?

the cell membrane
Where are phospholipids found? Each one of your cells is encased in a lipid layer called the cell membrane. The health of our cell membrane and the specific phospholipid content of it is integral to cellular metabolism.Nov 23 2020

How does the body use triglycerides?

When you consume — or your body creates — excess triglycerides they’re stored in fat cells for later use. When they’re needed your body releases them as fatty acids which fuel body movement create heat and provide energy for body processes. For good health your triglyceride level should be less than 150 mg/dL.

What is the name of the primary triglyceride stored in the animal body?

Triacylglycerol (Triglyceride) Triacylglycerol is the major form of dietary lipid in fats and oils whether derived from plants or animals. Triacylglycerol is composed of three fatty acids esterified to a glycerol molecule (Figure 4).

Why do we store triacylglycerol triglyceride?

What are triacylglycerols composed of? Glycerol backbone and 3 fatty acids. Why do we store triacylglycerol (triglyceride)? … As a substrate for the citric acid cycle for energy production.

What is the cellular location of triacylglycerols when stored?

For example within the liver triacylglycerols are stored as lipid droplets in the cytoplasm adjacent to the endoplasmic reticulum where a triacylglycerol hydrolase can effect lipolysis to di- and monoacylglycerols that are more soluble in the membrane which they are able to cross.

Which lipoprotein has the highest proportion of triglyceride?


Chylomicrons – these are the largest and least dense of the lipoproteins with the highest triglyceride content. They consist of a protein component synthesized in the liver which wraps around diet-derived cholesterol and fats.

Where are carbohydrates digested?

Digestion of Carbohydrates

Digestion of starches into glucose molecules starts in the mouth but primarily takes place in the small intestine by the action of specific enzymes secreted from the pancreas (e.g. α-amylase and α-glucosidase).

Where does the vast majority of nutrient absorption occur in the digestion system of mammals?

The small intestine is the part of the gastrointestinal tract between the stomach and the large intestine where much of the digestion of food takes place. The primary function of the small intestine is the absorption of nutrients and minerals found in food.

Do carbohydrates contain nitrogen?

Some carbohydrates contain the elements nitrogen and sulphur. One of the carbon atoms forms a carbonyl (aldehyde or ketone) group whilst the other carbon atoms exhibit hydroxyl groups.

Where is the macromolecule protein found?

Types of biological macromolecules
Biological macromolecule Building blocks Examples
Lipids Fatty acids and glycerol Fats phospholipids waxes oils grease steroids
Proteins Amino acids Keratin (found in hair and nails) hormones enzymes antibodies
Nucleic acids Nucleotides DNA RNA

Where are proteins digested?

Protein is a vital nutrient for almost every part of your body. It’s digested in your mouth stomach and small intestine before it’s released into your bloodstream as individual amino acids.

What is the main cause of high triglycerides?

The most common causes of high triglycerides are obesity and poorly controlled diabetes. If you are overweight and are not active you may have high triglycerides especially if you eat a lot of carbohydrate or sugary foods or drink a lot of alcohol.

What are the major functions of fatty acids and triglycerides in the body?

What are the major functions of fatty acids and triglycerides in the body? To insulate and protect the body to aid in transport of fat-soluble vitamins and to provide energy.

Why are triglycerides ideal for fat storage?

The main type of fat we consume triglycerides are especially suited for energy storage because they pack more than twice as much energy as carbohydrates or proteins. Once triglycerides have been broken down during digestion they are shipped out to cells through the bloodstream.

Where does triglyceride synthesis occur?

Synthesis of triglycerides occurs in most cells but predominantly occurs in intestinal enterocytes for the delivery of dietary fatty acids to the body and hepatocytes of the liver for the delivery of endogenous fatty acids to primarily cardiac and skeletal muscle and to adipocytes.

What are the structures of triglycerides?

Triglycerides are esters in which three molecules of one or more different fatty acids are linked to the alcohol glycerol they are named according to the fatty acid components e.g. tristearin contains three molecules of stearic acid and oleodistearin one of oleic acid and two of stearic acid.

Are triglycerides hydrophobic?

A common fat molecule or triglyceride. These types of molecules are generally hydrophobic and while they have numerous functions are probably best known for their roles in body fat and plant oils. A triglyceride molecule derived from two types of molecular components—a polar “head” group and a nonpolar “tail” group.

Where does triacylglycerol that is synthesized in adipose tissue go?


Triacyglycerol synthesis on the other hand occurs in the endoplasmic reticulum membrane of cells by bonding three fatty acid molecules to a glycerol molecule. Both processes take place mainly in liver and adipose tissue. Nevertheless it also occurs to some extent in other tissues such as the gut and kidney.

How are triacylglycerol molecules stored in the adipocytes and released when needed?

Triglycerides stored in the adipose tissue form a huge reservoir of metabolic fuels. The adipose tissue specializes in the esterification of fatty acids and their release from triglycerides. … Triglycerides are hydrolyzed to fatty acids and glycerol by intracellular lipases.

How triglycerides are formed in adipose tissue?

Triglycerides are the major dietary fat. … Adipose tissue triglyceride represents the major energy store of the body. Fatty acids are mobilized from adipose tissue triglycerides by the action of hormone-sensitive lipase (HSL) which is activated by glucagon and adrenaline (epinephrine) and inhibited by insulin.

Where in the body do we find the greatest storage of potential energy muscle glycogen blood glucose muscle protein body fat?

The liver has the highest concentration of stored glycogen however skeletal muscle as a result of its total weight is the largest reserve of stored glycogen in the body. Intramuscular glycogen is associated with several organelles including the sarcolemma sarcoplasmic reticulum mitochondria and myofibrils.

Where in the body is energy stored?

Energy is actually stored in your liver and muscle cells and readily available as glycogen. We know this as carbohydrate energy. When carbohydrate energy is needed glycogen is converted into glucose for use by the muscle cells. Another source of fuel for the body is protein but is rarely a significant source of fuel.

What is the major source of stored energy in the body?

Carbohydrates such as sugar and starch are readily broken down into glucose the body’s principal energy source. Glucose can be used immediately as fuel or can be sent to the liver and muscles and stored as glycogen. The body constantly uses and replenishes its glycogen stores.
