What is Protein?

All living cells contain protein. It follows from this that protein is a substance necessary for life. Indeed, our word "protein" comes from the Greek word for "first", because protein is considered the most important element of living matter.

Each type of cell has its own protein. Proteins are made from a combination of substances called amino acids. There are over twenty-one types of amino acids. Each amino acid group includes elements such as nitrogen, carbon, hydrogen and oxygen. Different amino acids can combine in different ways to make a protein, which has resulted in thousands of different proteins.

For example, meat is known to contain protein, but did you know that meat contains at least twelve to fifteen types of protein? Many foods that are considered healthy for us are so because they contain the proteins we need. This includes milk, eggs, lean meats, fish, peas, beans, peanuts, and some grains. They are important for a person because they supply him with amino acids that his body is not able to produce on its own. It must obtain amino acids from the proteins contained in the food. They are called "essential amino acids", which means that the body cannot do without them.

Certain types of amino acids, and in significant amounts, are required by our body tissues so that they can use what they need to function properly. Vegetable proteins, such as peas, beans and cereals, do not contain all the necessary amino acids. But they are still very valuable in the diet if combined with some animal proteins. The human body cannot store amino acids for future use. This means that we need to take all the necessary types of these acids at the same time.

Bread and milk should be eaten at the same meal so that the amino acids they contain can be used together to form new body tissues. A moderate amount of various protein-containing foods should be taken with meals. With all of this in mind, you will be getting enough of the essential amino acids to meet your body's protein needs.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Corks need to be fried 07.01.2000

Expert tasters say that about five percent of the time a good wine can be spoiled by a cork. Cork tones are woven into the bouquet of a noble drink, greatly reducing its price. This specific smell of cork is produced by fungi and microbes that have settled in its pores. For wines that are not intended for long-term storage, this does not matter much, they can even be plugged with a plastic cork, since nothing will pass from the cork into the wine in a few months. But for expensive collection wines aged for several decades, this is a problem.

Corks are sterilized by heating, but in the depth of the material a temperature of no higher than 50 degrees Celsius is reached, which is not enough to kill microorganisms. Employees of the Institute of Viticulture in Neustadt (Germany) suggested heating the corks with microwaves before corking. The institute has created a tunnel microwave oven with 70 generators, past which traffic jams pass on the conveyor. Next year, many European winemakers intend to purchase such stoves.
