All four are important. Carbohydrates and lipids make up the majority of structures in cells. Proteins make up the majority of enzymes and drive energy production in the cell. But none would exist without the genetic code stored by nucleic acids in DNA. So I think nucleic acids are the most important.

The common organic compounds of living organisms are carbohydrates, proteins, lipids, and nucleic acids. Each of these are macromolecules or polymers made of smaller subunits called monomers. The bonds between these subunits are formed by a process called dehydration synthesis.
Now that we’ve discussed the four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), let’s talk about macromolecules as a whole.
Each is an important cell component and performs a wide array of functions. Combined, these molecules make up the majority of a cell’s dry mass (recall that water.
Carbohydrates are one of the fundamental classes of macromolecules found in biology. Carbohydrates are commonly found in most organisms, and play important roles in organism structure, and are a primary energy source for animals and plants.

There are four macromolecules required for the healthy growth and development. these four categories of the macromolecules are the proteins, carbohydrates, nucleic acids, and fats.
Among these four categories of the macromolecules, the proteins are the only ones which contain nitrogen in them. Hence, the correct answer is 'protein'.
Structure and Function of Macromolecules - 2 Amino Acids and Proteins Proteins are very large molecules composed of combinations of about 20 different amino acids. The precise physical shape of a protein is very important for its function.
A single cell may h or more different proteins. This diversity of proteins is. Natural products research focuses on the chemical properties, biosynthesis and biological functions of secondary metabolites.
As our scientific understanding of all things 'natural' is. energy; a molecule of water is removed (dehydration) and a covalent bond is formed between the subunits (Fig.1). Breaking this bond is called hydrolysis; it requires the addition of a water molecule and releases energy.
Bio 3A Lab: Biologically Important Molecules Page 1 of 11 Each class of these macromolecules has. Biomolecule, also called biological molecule, any of numerous substances that are produced by cells and living organisms. Biomolecules have a wide range of sizes and structures and perform a vast array of functions.
The four major types of biomolecules are carbohydrates, lipids, nucleic acids, and proteins. Carbon chains form the skeletons of most organic molecules. Functional groups combine with the chain to form biomolecules. Because these biomolecules are typically large, we call them macromolecules.
Many biologically relevant macromolecules are formed by linking together a great number of identical, or very similar, smaller organic molecules. "Macromolecules" provides a brad survey of the entire subject; integrated representations of chemistry, physics, and technology; precise descriptions and definitions of basic phenomena; and balanced treatments of facts and theory.
the book series thus intends to bridge the gap between introductory textbooks and the highly specialized texts and monographs that cover only part of Author: Hans-Georg Elias.
Publisher Summary. This chapter provides an overview of biological molecules. The word cell was introduced to biology in by Robert Hooke in his collection of microscopic drawings, called Micrographia, which included one of a thin slice of are 92 natural chemical elements of which living cells contain only approximately Molecular aspects of type 1 diabetes.
class I molecule and (B) an HLA class II molecule, showing the antigen binding clefts. using x ray crystallography and computer modelling have suggested that HLA molecules associated with susceptibility to type 1 diabetes share similar chemical and geometric properties in their antigen binding by: Physical properties refer to when an atom or a molecule is observed without any chemical change of the substance.
For instance, boiling point, melting point, color, and odor are physical proper- ties. Practical examples are when aspirin melts at °C, acetic acid melts at °C, and salicylic acid melts at ºC.
Water can dissolve most of the biologically important molecules. (3). It is the solvent of life. The life originated in water and adapted to survive only in the presence of water. (4). About 70 to 90% of a cell occupies water. Biological Molecules of Life Jessica Leonard Biology Lab April 5, Abstract This lab was done to test for macromolecules consisting of carbohydrates, lipids, proteins, and nucleic acids by using specific reagents to test for each.
The result would bring out a specific color change in the macromolecule. Macromolecules are large molecules composed of thousands of covalently connected atoms. Carbohydrates, lipids, proteins, and nucleic acids are all macromolecules. Macromolecules are formed by many monomers linking together, forming a polymer.
Carbohydrates are composed of carbon, oxygen, and hydrogen. The monomer of carbohydrates are monosaccharides. This illustrates an important aspect of coordination chemistry, namely that the positive charge on the metal ion stabilizes the acid anion of protonated ligands.
The same thing is true for other biological ligands, such as water, alcohols, carboxylic.

Glucose is additionally utilized to make the molecule NADPH, which is important for protection against oxidative stress and is used in many other chemical reactions in the body.
If all of the energy, glycogen-storing capacity, and building needs of the body are met, excess glucose can be used to make fat. International Journal of Biological Macromolecules is an established international journal of research into chemical and biological aspects of all natural presents the latest findings of studies on the molecular structure and properties of proteins, macromolecular carbohydrates, glycoproteins, proteoglycans, lignins, biological poly-acids, and nucleic acids.
An important point about biological macromolecules is that, with the exception of lipids, their monomer units are polar, meaning that they have an electric charge that is not distributed symmetrically.
Schematically, they have "heads" and "tails" with different physical and chemical. Photochemical reactions of .etapentamethylcyclopentadienyl)dicarbonyliron alkyl and silyl complexes: reversible ethylene insertion into an iron-silicon bond and implications for the mechanism of transition-metal-catalyzed hydrosilation of alkenes.
One of the most-important aspects of the individual molecular parts and the complex things they constitute is the information that the parts contain and transmit.
In biology information in molecular structures—the chemical properties of molecules that enable them to recognize and bind to one another—is central to the function of all processes. Ion Channels. Ions such as sodium (Na +), potassium (K +), calcium (Ca 2+), and chloride (Cl-), are important for many cell e they are charged (polar), these ions do not diffuse through the membrane.
Instead they move through ion channel proteins where they are protected from the hydrophobic interior of the membrane. Macromolecules and the balance of diets What is a carbohydrate. What is a protein. A carbohydrate includes sugars and polymers of sugars.
The simplest carbohydrate are monosaccharides. A protein is a biologically functional molecule that has one or more polypeptides folded and. The increased use of radioisotopes has led to increased concerns over the effects of these materials on biological systems (such as humans). All radioactive nuclides emit high-energy particles or electromagnetic waves.
When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious Author: OpenStax. This video, as stated in the description, focuses on general functions of biomolecules. The biomolecules: carbs, lipids, proteins, and nucleic acids, can all can have important functions in the body.
Chemical space — which encompasses all possible small organic molecules, including those present in biological systems — is vast. So vast, in fact, that so far only a tiny fraction of it has Cited by: Paul Andersen describes the macromolecules that make up living organisms. He starts with a brief description of organic chemistry and the importance of functional groups.
