How is the type of fatty acid present in a neutral fat or phospholipid related to that molecules properties?
The type of fatty acid presented in a neural fat are one (monoglyceride) two (diglyceride) and three (triglyceride) fatty acids. They relate to this molecules properties because they make up the fats and oils found in plants and animals.
In phospholipids they consist of a glycerol attached to two fatty acid chains and a phosphate group. the phosphate end of the molecule is attracted to water (it is hydrophillic) while the fatty acid end is repelled (hydrophobic). these properties help this molecule repel and attract water, functions of a cell membrance.
well all i know 11 year student, double check because i will.
What else can I help you with?
What is the figure that gives the number of identical molecules in a formula?
The subscript in a chemical formula indicates the number of identical molecules present. For example, H2O indicates two molecules of water present.
What is the general structure of the plasma membrane?
Plasama membrane is adjecent or near the secondary cell wall in a cell. It is a living outermost boundary of all the cells. ULTRA STRUCTURE: It consist of three layer that is two protein layers on either side and a double middle layer of phospholipids. The conteneous layer of proteins sandwich the central phospholipid bilayers. Recently Singer and Nicholson proposes the fluid mosaic model of plasma membrane which states that there are two types of protein found in P.M. 1 Periheral or extrinsic protein : which is loosley bound to the lipid layer and is of floating type. It can be remove easily. 2 Integral or intrinsic protein: they are embeded in central phospholipid bilayers attached with oligosaccharide and can not remove easily. Carbohydrates are also present in plasma membrarne mainly bound to glycoprotein and also to glycolipids. Carbohydrate mainly in glycoprotein play an important role in cell that is cell recognization.
What does 6h2o stand for?
6H2O represents 6 molecules of water. The "6" indicates the number of water molecules present.
Why are they assuming the large molecules will stay on their own side of the membrane?
The assumption that large molecules will stay on their own side of the membrane is based on the principle of selective permeability. Membranes are selectively permeable, meaning that they allow some molecules to pass through while blocking others based on size, charge, and other properties. Large molecules may be physically unable to pass through the membrane due to size or may require specific transport mechanisms that are not present.
Is ribose present in DNA?
Yes, ribose is present in DNA as part of the sugar-phosphate backbone of the nucleotide molecules that make up the DNA structure.
Plasma membrane in eukaryotic cells is made up of?
The plasma membrane in eukaryotic cells is primarily composed of a phospholipid bilayer. This bilayer contains embedded proteins that help regulate the movement of molecules in and out of the cell. Additionally, cholesterol molecules are also present in the plasma membrane to provide stability and fluidity.
What types molecules are present in cell membrane?
The cell membrane is composed of different kinds of molecules. The phospholipid chains surround the cell and is what the cell membrane is primarily made of. Around the cell, you can also find proteins embedded on or all the way through the cell. This protein helps large molecules from outside the cell or inside the cell to go in or out. Between the phospholipid is also cholesterol which helps the cell membrane fluidity. This all being said, there are three things that make up the cell membrane: # The phospholipid bilayer # The protein inside and outside the cell # cholesterol between some phospholipid chains.
What is 1 element which is present in a phospholipid and not present in chitin?
Phosphorus is only present in a phosphorous but not in chitin so your answer is Phosphorus :)
How do you determine the phospholipid composition of a lecithin?
The phospholipid composition of lecithin can be determined using techniques such as thin-layer chromatography (TLC) or liquid chromatography (HPLC). These techniques separate and quantify the different phospholipid species present in the lecithin sample. Mass spectrometry can also be used to identify and quantify individual phospholipid molecules within the sample.
How can you tell if a substance is a neutral?
A substance is neutral if it has an equal number of positive and negative ions present, resulting in a net charge of zero. This balance in charges means that the substance will not exhibit any acidic or basic properties.
What is the number used to represent a neutral solution?
A neutral solution is represented by a pH of 7. This number signifies the balance between acidic and basic properties in the solution, with equal concentrations of hydrogen ions (H+) and hydroxide ions (OH-) present.
What molecules are in mild steel?
A combination of two elements, iron and carbon, where other elements are present in quantities too small to affect the properties, such as trace amounts of sulphur.
Mass intensive or extensive?
Intensive properties are not determined by the amount of a substance, rather the properties are inherent to the substance in question. Properties such as chemical reactivity, boiling point, density, etc are examples of intensive properties. Extensive properties are determined by the amount of substance that is present, mass falls under this category because it increases as the number of substance molecules increase.
Where is cholesterol found in cell membrane?
The plasma membrane is present in all prokaryotic and eukaryotic cells. It is the semi-permeable membrane that encloses the cell. So to clearly answer your question, the plasma membrane is found on the outside of the cell; it encircles the cell.
What geometries tend to be present in polar molecules?
Trigonal planar and tetrahedrral geometries tend to be present in polar molecules.
What happens to the molecules in a liquid when it melts?
When a solid melts, intermolecular forces that were holding the molecules tightly together are overcome by the kinetic energy introduced by heating the substance. All of the molecules are still present; they are just more widely dispersed and can move more freely, causing the fluid properties of liquids.
The cell membrane is composed of?
The cell membrane is composed of a double layer of phospholipid molecules with proteins embedded within it. This structure provides a selective barrier that controls the movement of substances in and out of the cell. Additionally, cholesterol molecules are also present in the cell membrane, helping to maintain its fluidity and stability.
