Lipids
Lipids are part of a group of molecules which consist of fats, sterols, vitamins, phospholipids and others.
We can find in our cell membrane glycerol-phospholipids (phospholipids), which are part of the lipid bilayer. The phospholipids can be found in biological membranes and their main function is to bind proteins from the outside to the inside of cell membrane.
The structure of phospholipids is:
The phospholipids have 2 fatty acids and 2 long CH2 chains which are attached to a glycerol top.
The glycerol has a phosphate group which is hydrophilic –‘attracted to water’ complete opposite to the fatty acids chain which is hydrophobic – ‘scared of water’.
The glycerol is an alcohol which is an organic compound with hydroxyl

In general lipids are known as fats, and even though the normal idea in society that fats aren’t good for our body that isn’t always true. Fats can be of extreme help, our body uses fats to produce energy and protect us.
Lipids will come into work and store energy if a large number of unneeded fats are consumed; they will store the calories in adipose cells and release them again when necessary such as while exercising.
Another way fats are helpful to our body is in order to protect us; lipids use fats to isolate our body to maintain our balanced temperature also it can be found surrounding our main organs (kidneys and heart) serving as protection in case of injuries.
Last but not least our body uses lipids while digesting food; here lipids will support the body absorbing nutrients. The bile acids in our liver will allow the mixture of water and fats in order to break down and absorb food which will later on be ‘translated’ into vitamins and used to maintain our vision and blood correct levels.
DNA – deoxyribonucleic acid
DNA is composed by a double helix structure. In this structure we can find a phosphate group, a deoxyribose and a nitrogenous base.
DNA as we know is a molecule which carries our genetic material; this will have all the coded information necessary of our
The body needs certain fatty acids that the body is unable to make themselves; these fatty acids can be found in vegetables, seeds and different types of fish. Lipids also play a role in the immune system, our vision as well as helps with the productions of hormone-like substances. Lastly, some lipids contain a source of vitamin A, vitamin D, Vitamin E, Vitamin K and helps to make the skin healthy.
c)Lipids monomer(s) are called fatty acid and glycerol. The functional group is called ester. The linkage type of lipids is non polar bonds or sometimes called ester bonds. The primary function of lipids is energy, hormone production and insulation of the body.
(a.) Lipids are the foundation of membranes. They are carbon-containing compounds that are found in organisms and are largely nonpolar and hydrophobic.
Then, nucleic acids are made up of nucleotides and has the ability to make new cells. Finally, Lipids. Lipids are made up of glycerol and fatty acids. Lipids play a big role in the body, it provides cushion and insulation for the larger organisms in our bodies. All of these macromolecules and monomers are needed to make energy.
(TCO 5) ________ are the major form of fat in both food and the body.
Lipids are fats and oils and have no true monomers, but they are made of glycerol and fatty acids. Lipids can be saturated, which means that every carbon has a single bond and has the maximum number of hydrogens possible, and they can be unsaturated, which means the carbons can have double bonds and not the maximum number of hydrogen. Lipids store energy, act as insulation to organisms, and protect organs from injury. Nucleic acids are made of monomers called nucleotides, and they make up the DNA and RNA of an organism. They have the information needed to produce proteins needed for a person’s body.
wonder what exactly is DNA? DNA is a term used for deoxyribonucleic acid and it
Lipids and Carbohydrates Lipids are a group of substances, which include fats, oils and waxes. Carbohydrates include sugars, starches, glycogen and cellulose. They are stored in plants as starches and in animals as glycogen. There are many differences between carbohydrates and lipids.
The good form of this sterol in the body is your HDL, because it picks up all the bad form in your body and store it in the liver to be converted into the bile then exits out.
DNA, Deoxyribonucleic Acid, is the basic structure for all life, it is the blueprint, the instruction manual, on how to build a living organism. DNA is made up of four nitrogen bases, adenine, thymine, cytosine, and guanine which are connected by sugar-phosphate bonds. Through a process called Protein Synthesis, the nitrogen bases are the code for the creation of amino acids. Essentially, DNA makes amino acids, amino acids make proteins, proteins make organisms. This process has been taking place for much longer than scientists have been able to document. Those scientists are called geneticists and their field is genetics.
The functions of fat in our body are to maintain normal growth and development. The fat in our diet
DNA is a long curved structure, made up of pairs of four specific bases: adenine, guanine, cytosine, and thymine, is the repository of a code from which all of our cells are made. The code is made up of base pairs which look like the
There are four types of biomolecules, carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates are large chains of sugar found in food and living tissues. This includes sugars, starch, and cellulose. They have the same ratio of hydrogen and oxygen that water has, 2:1. They are broken down to release energy in the animal body. Lipids are any organic compounds that are fatty acids and don’t dissolve in water but do in organic solvents. Fatty acids can be found in natural oils, waxes, and steroids. Proteins are macromolecules that do everything in the cell. They are tools and machines that make things happen. Nucleic acids are long strands of nucleotides, and function primarily in storage and transmission of genetic information. There are two types of nucleic acids, DNA and RNA. DNA is the genetic material of all cellular organisms, and RNA sends out messages from the information that is held in the DNA.
Carbohydrates are the body’s primary source of energy. Without adequate carbohydrates, a person may feel fatigued and weak, as the body looks elsewhere for sources of energy. A severe lack of carbohydrates can deprive critical bodily organs the necessary energy to properly function. Lipids are naturally occurring organic compounds that include fats and oils. An excess of some lipids can increase the chances of certain health problems, lipids are vital nutrients to a healthy body. Lipids are necessary for the absorption of fat soluble vitamins. A diet too low on lipids lowers the level of good cholesterol, decreases the body’s energy level and can disturb the body’s formation of cells and cell functions.
Most organic compounds in living organisms are carbohydrates, proteins, lipids, and nucleic acids they are called macromolecules. Each of these macromolecules is made of smaller subunits. These subunits are linked by dehydration synthesis. Dehydration synthesis is an energy requiring process in which a molecule of water is removing and the two subunits are boded
