What kind of matter is life made of? What is life made of?

Amino acids and nucleotides are the most important components of the necessary building blocks in living organisms on Earth. Protein is a complex organic compound formerly known as a "prion". Proteins, on the other hand, are formed by the linear arrangement of amino acid molecules, and the carboxyl and amino groups of adjacent amino acid residues are linked together by forming peptide bonds.

Nucleotides usually form commands to the combination of amino acids through different combinations.

With our current state of technology, at most we can create some relatively low-level viruses and other diseases. The higher beings are extremely complex systems, and when they collapse completely, we have no power to fully recover them. Life is only a form of a certain stage of matter, it cannot exist forever, and death is a normal means of material circulation in the universe as we know it, and we must get used to it.

1. Sugars, lipids, nucleic acids, proteins, and indispensable vitamins.

2. This question. I guess no one can get you.

Made up of cells! Because the cell is the most basic unit of life.

Analysis: Biological macromolecules refer to some polymers with complex tissue structures in the living body, which are the main material basis of life activities, so they are called living substances. The main types of biological macromolecules are proteins, nucleic acids, polysaccharides, and lipids.

Protein is an important component of living organisms, and its weight accounts for more than half of the dry weight of cells (muscles, **, blood, hair. Involved in all life activities (catalytic reactions, metabolic regulation, body movement, material transport, immune defense, genetic control, memory, thinking). Among them, it is enzyme proteins that catalyze and regulate the role of organisms, myosin and actin that are responsible for muscle contraction, and the characteristics of intracellular protein-lipid complexes determine the active transport and energy conversion of cell membranes.

The basic unit that makes up proteins is amino acids, which have one carbon atom (carbon atom) and are surrounded by a carboxyl group, an alkaline amino group, a hydrogen atom, and a molecular group called a residue group (side chain), the general formula of which is shown in the figure on the right. There are 20 types of naturally occurring amino acids, and the table below lists their names, symbols, and their hydrophobicity.

There are many types of proteins, which are common in nature; There are 100,000 species of the human body. Due to the different structures of the long chain of the group, different shapes are formed to complete different functions. Below are the schematic diagrams of the four typical amino acid structures and protein structures:

Nucleic acid is a biological macromolecule that maintains the identity of living organisms, and is the carrier and transmitter of all information about the structure and behavior of living systems. Nucleic acids are multimers of nucleotides, which are made up of sugars, bases, and phosphoric acid. The distinction between DNA and RNA varies according to the structure of their sugars (as shown in the figure below).

Polysaccharides are multimers composed of sugars, whose main functions are the formation of surface agents (e.g., oryzanilin, mucus) and food storage. It can also form glycoproteins with proteins, which constitute some important physiological functions such as antibodies, enzymes, and hormones. It also forms glycolipids from fat, which are important parts of cell membrane structure and nerve tissue.

Lipids include fats and lipids. Fats are mainly used to store energy, and fats are used to facilitate fat digestion.

Our definition of life: (Life is the existence of time, a life form formed on the basis of evolution, and the form of life is the evolution of the artifact file over time.) Life is matter, life is time, it is the continuation of life.

It is the premise of our existence and development. We define life as: an organism that has self-continuity, can transform matter and energy into its own energy, and can realize communication and interaction with the outside world, and carry out self-renewal and development.

The existence and evolution of life forms on Earth are based on hypothetical explanations and the results of physics, which is a natural entity of "space-time".

1. What is the essence of the existence of life?

Physics believes that all matter is based on the universe as an entity, and space-time is the basic property of existence and development. However, there are still great questions about how it develops and evolves into what form, and how it communicates and interacts with the outside world. The existence of life is the process of energy transformation and energy exchange between the universes, so as to realize the flow and continuation of its own energy.

The existence and evolution of life is the change of matter and the circulation of energy. Material form: Matter is the medium and carrier for energy transformation and interaction between energy and matter.

Life form: the process of energy transformation and interaction in time and space. The existence of life is a process of energy flow and change, and life phenomena are constantly evolving and developing in the physical world.

2. How the evolution of life proceeds.

The evolution of life is a complex natural process, and the existence of nature and life is inseparable from "initial to infinite imitation". We know that within a complete cosmic system, there are countless different systems and levels. Different systems have different levels of compositional characteristics and interrelationships.

Among them, there are also the composition characteristics and interrelationships of different systems in many systems, and different kinds of life forms have been formed. The life form organism evolved from the biological system, and the biological system finally formed the life form after the structural adjustment and the evolution of the organizational form in different periods. Changes in the structure of the biological megasystem lead to changes in the energy** and life forms of the biological megasystem.

When the energy ** in the biological system changes, the biofiber system will inevitably undergo a new round of structural adjustment and finally form a life form.

Life is a high-level material phenomenon, which is higher than mechanical, physical, and chemical phenomena, but lower than the spiritual phenomenon.

The source body of life is a higher form of matter, and the (biological) movement is a form of advanced material cavity movement in the number disturbance state.
