What is a saturated fatty acid in biology?

Fatty acids may be saturated or unsaturated. In a fatty acid chain, if there are only single bonds between neighboring carbons in the hydrocarbon chain, the fatty acid is said to be saturated. Saturated fatty acids are saturated with hydrogen since single bonds increase the number of hydrogens on each carbon.

Which are saturated fatty acids?

The predominant saturated fatty acid in most diets is palmitic acid (C16:0); it is cholesterol-increasing when compared with cis-monounsaturated fatty acids, specifically oleic acid (C18:cis1, n-9), which is considered to be ‘neutral’ with respect to serum cholesterol concentrations.

What is saturated fatty acid with example?

The saturated fatty acids are derived from both animal fats and plant oils. Rich sources of dietary saturated fatty acids include butter fat, meat fat, and tropical oils (palm oil, coconut oil, and palm kernel oil). In the USA and much of Europe, saturated fatty acids make up 12–15\% of the total nutrient energy intake.

Why is it called saturated fatty acid?

Saturated fat contains triglycerides that consist only of saturated fatty acids. They are called “saturated” because there are no double bonds between the fatty acid chain and the carbon atoms, meaning the carbon atoms are fully filled or saturated with hydrogen atoms (unlike “unsaturated fats”).

What is a saturated fatty acid saturated with quizlet?

Fatty acids may vary in length (number of carbons) and in the number and locations of double bonds. If the fatty acid has no carbon-carbon double bonds, then the molecule is a saturated fatty acid, saturated with hydrogens at every possible position. Saturated fats are solid at room temperature.

What is the function of saturated fatty acids?

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). Saturated fats raise your LDL (bad) cholesterol. High LDL cholesterol increases your risk for heart disease and stroke.

What is meant by saturated vs unsaturated fatty acid?

1: 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.

What is meant by an unsaturated fatty acid?

Unsaturated fatty acids have one or more carbon-carbon double bonds. The term unsaturated indicates that fewer than the maximum possible number of hydrogen atoms are bonded to each carbon in the molecule. The oxidation of unsaturated fatty acids is autocatalytic; that is, it proceeds by a free-radical chain reaction.

What is unsaturated and saturated?

Unsaturated fats, which are liquid at room temperature, are different from saturated fats because they contain one or more double bonds and fewer hydrogen atoms on their carbon chains. Unsaturated fats come from plants and occur in the following kinds of foods: Olives.

What does it mean for a lipid to be saturated or unsaturated quizlet?

saturated fat. a lipid made from fatty acids that have no double bonds between carbon atoms. unsaturated fat. a lipid made from fatty acids that have at least one double bond between carbon atoms. You just studied 5 terms!

What is distinguishing characteristic of a saturated fatty acid?

Saturated fats have no double bonds in their chemical structure. They are saturated with hydrogen atoms. Because of their chemical structure, they have a solid consistency at room temperature.

Which fats are good and bad?

For long-term health, some fats are better than others. Good fats include monounsaturated and polyunsaturated fats. Bad ones include industrial-made trans fats. Saturated fats fall somewhere in the middle. All fats have a similar chemical structure: a chain of carbon atoms bonded to hydrogen atoms.

Which food has more saturated fat?

fatty pieces of meat such as beef and lamb
