Which molecules are found in lard and butter?
Fats (and oils) are made up of a group of molecules called triglycerides (read a more extensive introduction to fat). Lard is made up of a mixture of different triglycerides, as are olive oil, butter and coconut oil.
What feature could you look for to determine whether the nucleic acids of this virus are RNA or DNA?
What feature could you look for to determine whether the nucleic acids of this virus are RNA or DNA? If it is RNA, it will contain ribose. Dehydration synthesis involves the removal of a hydrogen ion and a hydroxyl ion.
What combination of these fatty acids could you use to make a fat that is liquid at room temperature?
Foods rich in unsaturated fatty acids, such as olive oil (oleic acid, an eighteen-carbon unsaturated fatty acid, is a major component) tend to be liquid at room temperature. Flaxseed oil is rich in alpha-linolenic acid, which is an unsaturated fatty acid and becomes a thin liquid at room temperature.
What organelle makes lipids?
endoplasmic reticulum The organelle called 'endoplasmic reticulum' occurs in both plants and animals and is a very important manufacturing site for lipids (fats) and many proteins.
Why is lard solid at room temperature?
Why is lard solid at room temperature? Lard and butter are animal fats and their fatty acids are “saturated” meaning no double bonds. On a molecular level saturated fats are very straight and linear so stacking them is easy like putting crayons or pencils in a box and this makes them solid on a macro scale.
Is lard a triglyceride?
Lard consists mainly of fats, which in the language of chemistry are known as triglycerides. These triglycerides are composed of three fatty acids and the distribution of fatty acids varies from oil to oil. In general lard is similar to tallow in its composition.
How do you identify viruses?
Currently, nucleic-acid detection and immunoassay methods are among the most popular means for quickly identifying viral infection directly from source. Nucleic acid-based detection generally offers high sensitivity, but can be time-consuming, costly, and require trained staff.
What are the methods of identifying viruses?
The most widely employed methods are viral culture and antigen detection by FA staining or EIA. Suitable specimens include nasopharyngeal aspirates, washings, or swabs; bronchial washings; and bronchoalveolar lavage fluid.
Why fats are solid at room temperature and oils are liquid at room temperature?
Building blocks of fat The close packing of these blocks is similar to the tightly packed molecules that make saturated fats appear solid. The building blocks of unsaturated fats have bends or kinks that don't allow the blocks to be tightly stacked and thus, appear more fluid and are liquid at room temperature.
Which type of fatty acid is a solid at room temperature?
Saturated fatty acids Saturated fatty acids, such as stearic acid (18 carbons) or palmitic acid (16 carbons) are solid at room temperature whereas unsaturated fatty acids, like linoleic acid (18 carbons with two double bonds at the 9 and 12 positions) can be liquid (Table 7.6).
What organelle is responsible for lipid metabolism?
The endoplasmic reticulum (ER) The endoplasmic reticulum (ER) is the main site for lipid synthesis.
What organelle makes lipids rough or smooth?
The smooth endoplasmic reticulum functions in many metabolic processes. It synthesizes lipids, phospholipids as in plasma membranes, and steroids.
What fat is solid at room temperature?
Saturated Fat What Is Saturated Fat? Tightly-packed fats that are solid at room temperature because they contain no double bonds in their chemical structures are known as saturated fats — because their structures contain as many hydrogen atoms as possible and they are "saturated" with hydrogen.
What is triglyceride?
What are triglycerides? Triglycerides are a type of fat (lipid) found in your blood. When you eat, your body converts any calories it doesn't need to use right away into triglycerides. The triglycerides are stored in your fat cells.

Why are saturated triglycerides solid at room temperature?
Since the fatty acids in these triglycerides contain the maximum possible amount of hydrogens, these would be called saturated fats. The hydrocarbon chains in these fatty acids are, thus, fairly straight and can pack closely together, making these fats solid at room temperature.
What triglycerides are solid at room temperature?
These triglycerides (or triacylglycerols) are found in both plants and animals, and compose one of the major food groups of our diet. Triglycerides that are solid or semisolid at room temperature are classified as fats, and occur predominantly in animals….Fats and Oils.

Where are triglycerides synthesized in the cell?
the endoplasmic reticulum Triglyceride synthesis Triglycerides are synthesized by esterification of fatty acids to glycerol. Fatty acid esterification takes place in the endoplasmic reticulum of cells by metabolic pathways in which acyl groups in fatty acyl-CoAs are transferred to the hydroxyl groups of glycerol-3-phosphate and diacylglycerol.
Which organelle is used to create triglycerides and other lipids?
The smooth endoplasmic reticulum Which organelle is used to create triglycerides and other lipids? Explanation: The smooth endoplasmic reticulum serves several different purposes in the cell, one of which is lipid synthesis.
What is the difference between rough ER and smooth ER?
The most basic difference between RER and SER is the presence of ribosomes. When ribosomes attach to the surface of an ER, it gives a characteristic rough appearance; hence it is called Rough ER. On the other hand, a smooth ER does not have ribosomes on its surface. It possesses ribosomes attached to its membrane.
How are lipids made in the smooth ER?
The smooth endoplasmic reticulum plays a major role in synthesizing lipids by means of enzymes embedded in these smooth membranes.
Why fat are solid at room temperature?
Fats come in multiple forms, saturated, unsaturated and trans fats just to name a few. Saturated fats are solid at room temperature due to their molecular shape. The term saturated is in reference to an sp3 carbon chain that has its remaining sp3 orbitals bonded with hydrogen atoms. Thus the term “saturated”.
What are triglycerides made of?
Triglycerides (TGs) are nonpolar lipid molecules composed of a glycerol molecule associated with three fatty acid (FA) molecules, and they represent the main form of lipid storage and energy in the human organism (1,2).
What is the function of triglycerides?
Triglycerides are lipids (waxy fats) that give your body energy. Your body makes triglycerides and also gets it from the foods you eat. High triglycerides combined with high cholesterol raise your risk of heart attack, strokes and pancreatitis. Diet and lifestyle changes can keep triglyceride levels in a healthy range.
