Are saturated fats straight chain molecules?

Saturated fatty acids tails are straight, so fat molecules with fully saturated tails can pack tightly against one another. In contrast, cis-unsaturated fatty acid tails are bent due to the cis double bond. This makes it hard for fat molecules with one or more cis-unsaturated fatty acid tails to pack tightly.

What are saturated fatty acid chains?

Saturated fatty acids are straight-chain organic acids with an even number of carbon atoms (Table 2). All saturated fatty acids that have from eight to 16 carbon atoms increase the serum LDL cholesterol concentration when they are consumed in the diet.

Do saturated fatty acids have straight carbon chains?

Saturated fatty acids have perfectly straight chain structure. Unsaturated ones are typically bent, unless they have a trans configuration.

Are saturated fats good for you?

Saturated fats are bad for your health in several ways: Heart disease risk. Your body needs healthy fats for energy and other functions. But too much saturated fat can cause cholesterol to build up in your arteries (blood vessels).

How much saturated fat should I eat per day on a 1200 calorie diet?

Nutrition and healthy eating Answer From Katherine Zeratsky, R.D., L.D. The Dietary Guidelines for Americans recommends limiting saturated fat to 10% or less of your daily calories.

How are hydrocarbon chains connected in saturated fatty acids?

Fatty Acids Saturated fatty acids have hydrocarbon chains connected by single bonds only. Unsaturated fatty acids have one or more double bonds. Each double bond may be in a cis or trans configuration. In the cis configuration, both hydrogens are on the same side of the hydrocarbon chain.

How many bonds are there in a saturated fat?

Carbon atoms almost always have four bonds to other atoms. For the long chains that make up a saturated fat, all of the carbon-carbon bonds are single bonds, and each car- bon is attached to two hydrogens, except for the last one, the chain ender, which gets three.

How are saturated and unsaturated fatty acids classified?

Saturated and unsaturated refer to the extent to which the carbon atoms in the molecule of fatty acid are linked or bonded (saturated) to hydrogen atoms. One system of fatty acid classification is based on the number of double bonds. 0 double bonds: saturated fatty acids.

Which is the more nutritional part of the fat molecule?

Fatty acids are the more nutritionally important part of the fat molecule, and they are the ones that determine the chemical differences between different types of fat molecules. Fatty acids are made up of a long chain of carbon atoms (5, 10 or 18 atoms long, or even longer), with one acidic group (-COOH).
