Which of the following substances is a saturated fatty acid?
So, the correct answer is 'Palmitic acid'.
What is the maximum number of grams of fat that can be consumed by a person who eats 2400 calorie per day and wants no more than 30% of her calories to be from fat?
Max eats 2,400 calories per day and wants no more than 30 percent of his calories to be from fat. What is the maximum number of fat grams he can eat in a day? 20 to 35 percent.
How many different forms of lipids are commonly found in food?
How many different forms of lipids are commonly found in food? Three types of lipids—triglycerides, phospholipids, and sterols—are commonly found in food.
Which of the following types of lipoprotein contains the highest percentage of protein quizlet?
HDL has the highest percentage of proteins.
What helps to remove cholesterol from the cells and delivers it to the liver?
HDL stands for high-density lipoproteins. It is sometimes called the "good" cholesterol because it carries cholesterol from other parts of your body back to your liver. Your liver then removes the cholesterol from your body.
Why are lipids insoluble in water?
Lipids are a large and diverse class of biological molecules marked by their being hydrophobic, or unable to dissolve in water. The hydrophobic nature of lipids stems from the many nonpolar covalent bonds. Water, on the other hand, has polar covalent bonds and mixes well only with other polar or charged compounds.
Why are lipids waterproof?
Lipids are non-polar molecules, so they are not soluble in polar solvents like water. If you've ever tried to combine oil and water, you've seen how poorly they mix. This feature of lipids allows our bodies to use them as waterproof barriers and as biological membranes.
What is the recommendation for carbohydrate intake for an athlete who consumes 2800 calories per day?
The USDA recommends that 45 to 65 percent of your total daily calories come from carbohydrates. For example: To consume 60% of total daily calories from carbohydrate sources: A moderately active 18-year old male who requires 2800 calories a day would need to consume 1680 calories from carbohydrate sources.
When following a normal diet a person should get what percent of their calories from carbohydrates?
45% to 65% The Dietary Guidelines for Americans recommend that carbohydrates make up 45% to 65% of total daily calories. So if you get 2,000 calories a day, between 900 and 1,300 calories should be from carbohydrates. That translates to between 225 and 325 grams of carbs a day.
Which lipid is soluble in water?

Is a lipid insoluble in water?
Lipids are a large and diverse class of biological molecules marked by their being hydrophobic, or unable to dissolve in water. The hydrophobic nature of lipids stems from the many nonpolar covalent bonds. Water, on the other hand, has polar covalent bonds and mixes well only with other polar or charged compounds.
Which of the following is the largest of all lipoproteins in other words which one contains the greatest quantity of fat?
Chylomicrons – these are the largest and least dense of the lipoproteins, with the highest triglyceride content.
Which of the following lipoproteins contains the highest percentage of cholesterol and is associated with an increased risk of atherosclerosis?
Apolipoprotein B-100 There is a single molecule of Apo B-100 per VLDL, IDL, and LDL particle. Apo B-100 is a ligand for the LDL receptor and therefore plays an important role in the clearance of lipoprotein particles. High levels of Apo B-100 is associated with an increased risk of atherosclerosis.
What role do low density lipoproteins LDL play in cholesterol transportation?
Low-density lipoproteins (LDLs) transport cholesterol from its site of synthesis in the liver to the various tissues and body cells, where it is separated from the lipoprotein and is used by the cell.
Is the body required to make vitamin D bile acids and cortisol?
However, cholesterol is essential to the formation of bile acids, vitamin D, progesterone, estrogens (estradiol, estrone, estriol), androgens (androsterone, testosterone), mineralocorticoid hormones (aldosterone, corticosterone), and glucocorticoid hormones (cortisol).
Can lipids dissolve in water?
ChloroformBenzeneAcetoneToluene Lipid/Soluble in Lipids are all insoluble in polar solvents like water but highly soluble in the non-polar or weakly polar organic solvents, including ether, chloroform, benzene, and acetone.
Why are lipids hydrophobic?
Lipids are a large and diverse class of biological molecules marked by their being hydrophobic, or unable to dissolve in water. The hydrophobic nature of lipids stems from the many nonpolar covalent bonds. Water, on the other hand, has polar covalent bonds and mixes well only with other polar or charged compounds.
Do lipids dissolve in water?
Lipids are all insoluble in polar solvents like water but highly soluble in the non-polar or weakly polar organic solvents, including ether, chloroform, benzene, and acetone.
Are lipids hydrophobic or hydrophilic?
hydrophobic Molecules such as proteins, nucleic acids, and carbohydrates have an affinity for water and are called hydrophilic (“water-loving”). Lipids, however, are hydrophobic (“water-fearing”).
How can endurance athletes best postpone fatigue during their activity group of answer choices?
How can endurance athletes best postpone fatigue during their activity? Eat glucose periodically during the event.
Which of the following strategies helps endurance athletes maintain their blood glucose concentrations for as long as possible?
Strategies that help endurance athletes maintain their blood glucose concentrations for as long as they can include: eating a high-carbohydrate diet regularly.
When following a normal diet a person should get what percent of their calories from carbohydrates quizlet?
Adults should get 45 percent to 65 percent of their calories from carbohydrates, 20 percent to 35 percent from fat, and 10 to 35 percent from protein.

Is lipid soluble hydrophobic?
lipids. …for water and are called hydrophilic (“water-loving”). Lipids, however, are hydrophobic (“water-fearing”). Some lipids are amphipathic—part of their structure is hydrophilic and another part, usually a larger section, is hydrophobic.
Are lipids hydrophobic?
Lipids tend to be hydrophobic, nonpolar, and made up mostly of hydrocarbon chains, though there are some variations on this, which we'll explore below. The different varieties of lipids have different structures, and correspondingly diverse roles in organisms.
Why are lipids soluble in water?
They have long chains of nonpolar bonds, which makes them easily dissolvable in oil and grease; but they also have a polar charged group at one end, which makes them easily dissolvable in water.
Which of the following statements correctly describes the metabolic fate of the lipids transported by lipoproteins?
Which of the following statements correctly describes the metabolic fate of the lipids transported by lipoproteins? The LDL cholesterol interacts with receptor sites on the surface of cells to release cholesterol that can be used to make bile, hormones, and vitamin D.
What do chylomicrons low-density lipoproteins VLDLs and low-density lipoproteins LDLs all share in common?
What do chylomicrons, very low-density lipoproteins (VLDLs), and low-density lipoproteins (LDLs) all share in common? A. All three lipoproteins originate in the liver.
Is cholesterol hydrophobic or hydrophilic?
Cholesterol is referred to as an amphipathic molecule, that it contains its hydrophilic and hydrophobic parts. The hydroxyl group (-OH) in cholesterol is aligned with the phosphate head of the phospholipid on the cell membrane, which the rest of the cholesterol goes with the fatty acid of the membrane.
Why is cholesterol insoluble in water?
Each has a characteristic carboxyl group (the -COOH) attached to a chain of carbons with hydrogen atoms attached to the carbon chain. Two things are noteworthy. First, the hydrocarbon chain is very non-polar and therefore doesn't dissolve in water very well.
