Four Main Macromolecules
The Four Main Macromolecules
Interestingly enough, all cells that build up an entire organism, such as the human body, only consist of water, inorganic ions, and organic compounds as three dominant components. Together, water and inorganic ions such as Sodium, Magnesium, Calcium, Phosphate, etc. make up around 70% of the cell’s mass, while organic compounds make up the rest. Unlike its other two counterparts, organic compounds contain carbon-hydrogen reactions that allow them to create, sustain, and diversify all life on Earth, using the ability of carbon as an element to form a variety of biological molecules through covalent bonding. Organic compounds (otherwise known as carbon compounds) often consist of smaller molecules being stored by

Each carbohydrate molecule is made of one carbon atom, two hydrogen atoms, and one oxygen atom. A monosaccharide (simple sugar) is a structural form that consists of somewhere between 3-7 carbohydrate molecules attached together to form a chain. Two monosaccharides can be combined to form a larger carbohydrate molecule called a disaccharide. Polysaccharides are the largest of all the three combinations of carbohydrate molecules. Glucose and fructose are two examples of monosaccharides, and sucrose (table sugar) is a disaccharide because it can be formed by the combination of glucose and fructose molecules. Glycogen and starch are …show more content…
Glucose supplies energy that cells need to conduct cellular functions and processes. Glycogen, found in the liver and skeletal muscles, is a variant of glucose that also has a role in supplying energy to the body by breaking down into glucose when necessary. In plant cells, cellulose is an important carbohydrate that gives cell walls their structural support, which helps plants stand straight. Energy and physical support are two key purposes that carbohydrates serve to maintain homeostasis for cells and organisms overall.
In addition to carbohydrates, lipids are another type of macromolecules that are known for being hydrophobic and making up substances such as fats, oils, and waxes in many forms that provide various benefits to all organisms who need them. Lipids are made out of two main elements: carbon and hydrogen, while being consisted of fatty acids, glycerol, etc. The four main groups in which lipid molecules are classified are: fats, phospholipids, waxes, and

    Glycogen is sugar composed of multiple units of glucose linked together by α-1.4. glycosidic bond. These large units are called polymers, they also contain branched links every 8 – 10 units by a α-1.6. glycosidic bond (fig 1). These polymers form granules ranging in size from 10 – 40 nm (fig 2).…

What is the result of decreasing the number of double bonds? a. The oil now has a lower melting point. b. The oil is now a solid at room temperature. c. There are more “kinks” in the fatty acid chains. d. The oil is now a derivative carbohydrate. e. The fatty acid is now a triglyceride. 13.

    Carbohydrates - Complex carbohydrates are chains of simple sugars. Their primary role in animals is to provide energy. Plants use starch as an energy storage molecule, and use complex carbohydrates such as cellulose for support. Examples of carbohydrates are sucrose, glucose, fructose, starch, cellulose, and glycogen. A good dietary source for carbohydrates would be bread and grains.…

    A carbohydrate is an organic compound that is made up of oxygen carbon and hydrogen and includes both sugars and polymers of sugars. Carbohydrates are different from other organic compounds because it goes by the empirical formula of Cm(H2O)n and has a hydrogen to oxygen ratio of 2:1. There are three types of carbohydrates, the first being monosaccharides, which are simple sugars such as fructose and glucose. One of their main purposes is to act as an energy source for plants and animals; such as glucose being broken down during cell respiration. Monosaccharides are also monomers which serve as building blocks for more complex carbohydrates to form. Disaccharides is the second group and consists of two monosaccharides joined together by glycosidic linkage. They are common components found in what people eat and mainly serve to give nutrition to said diets. The third group is polysaccharides, the polymers of carbohydrates, which are made up of a few hundred to a few thousand monosaccharides. This…

    Identifying macromolecules in the foods we eat is essential in comprising a healthy well-rounded diet ensuring our nutritional needs for cellular processes in the human body. The largest biological molecules are known as carbohydrates, lipids, and proteins. Carbohydrates are compounds of monosaccharides, disaccharides, and polysaccharides known as sugars and starches. Lipids, known as fats, are storage molecules in animals and plants. Proteins bind to other molecules performing key roles in DNA and RNA functions.…

    When we eat foods that contain carbohydrates, the digestive enzymes in our mouth, stomach as well as intestine; help to rapidly break it down in to simple sugars and glucose. Once the glucose is absorbed into the bloodstream, it will then be distributed to cells and muscles with the help of insulin which enables the glucose to be ready for immediate use. However, it can be retained as a reserved energy in the liver and muscles in the form of glycogen or could potentially be stored as…

    1) What does the body use carbohydrates for? One of the main jobs of carbohydrates is to provide fuel for the body to do its job. So if we want to run or walk somewhere or play sports or even work -- all of those activities use carbohydrates. It is our main energy source and helps the body maintain energy.…

    All the four macromolecules=lipids, proteins, carbohydrates and nucleic acids= are essential for the functioning of an organism 's body (Campbell, biology). They work hand in hand to help us survive. For example, Lipids are an immediate energy source. ATP, for example, is used by the body when in energy deficit. Proteins are needed to form muscles and bones. Carbohydrates are the main energy source for the body. Without this energy, we would not be able to…

    All Biomolecules have certain functions and these molecules all have a unique structure which is why they function in these ways. These molecules are known collectively as macromolecules, these molecules are grouped into four main categories which each have there own structure. These structures are the key to the macromolecules functions as each of them do a specific task in the body. Macromolecules are grouped into carbohydrates, nucleic acids, proteins, and lipids. In most cases macromolecules are polymers, which is a long molecule which are made by linking together a large number of small, similar compounds called monomers.…

    Carbohydrates are made up of monomers called monosaccharides, which monosaccharides are made up of two different functional groups: carbonyl and hydroxyl. The second macromolecule is the lipid and the lipid is made up of three elements, which they are oxygen, hydrogen, and carbon. Lipids have monomers that are called fatty acids and these monomers are made up of carboxyl and methyl groups. This macromolecule is used for long term energy storage, insulation, waxes, and hormones. Third, proteins are the rulers of the world as they are present in almost every activity of living things.…

    According to the McKinley Health Center, the organic molecules included are carbohydrates, proteins, and lipids. Carbohydrates in particular are the essential fuel source for the human body’s mechanisms. They are stored in the tissues and cells of the body as glucose and as glycogen, the carbohydrate used for muscle movement, as well as in the liver, until the stored energy is used later (Volesky). The energy mobilized from carbohydrates is stored in the bonds between its monomers.…
