Nitrogen is important in building proteins in our body, where do we get the nitrogen that we need?

Answer 1

Nitrogen is part of proteins. Naturally, proteins are already manufactured from plants. Plants and some animals synthesize amino acids. Proteins are composed of amino acids which are commonly found in the foods we eat. Plants and some animals synthesize amino acids from nitrogen in their environment. Unfortunately, humans don't do this. Thereby, we are forced to get the amino acids from plants and animals. Amino acids can be supplied complete or incomplete from one source. Commonly plants, don't supply all the amino acids we need therefore a vegeterian has to eat a variety of plants to obtain all. Meat commonly supply complete protein.

Answer 2

Bula must be a self-loathing individual since he or she so vigorously hates stupidity. Philly guy is wrong, but not as Bula might suggest. The atmosphere contains a little over 78% nitrogen. Philly guy was right on. As far as Phoolish is concerned a significant portion of the nitrogen used for commercial farming is from industrially "fixed" nitrogen. On a global scale, however industrially fixed nitrogen represents about 20% of all nitrogen fixed. Biologically fixed nitrogen represents about 69% of the nitrogen fixed globally.

Nitrogen fixation is the conversion of dinitrogen into two molecules of ammonia (Nitrogen with three (or 4) hydrogens attached). Lightening fixes nitrogen.

Nitrogen fixation that occurs biologically is mediated by bacteria. The ammonia is converted to nitrate (Nitrogen with three oxygens attached) by other bacteria.

Plants such as legumes (beans) have nitrogen fixing bacteria associated with their roots in what are called nitrogen fixing nodules. In a proper rotation, beans will leave more nitrogen in the soil than they utilize. A high nitrogen using crops can grow with little or no added industrially fixed nitrogen if grown in the field that grew the beans. Some growers will grow beans in the spring and plow it under before planting. Such "cover" crops are an important element of sustainable agriculture.

Plants can absorb NO3 (nitrate) or NH3 (ammonia) from the soil. The amount of nitrogen from mineralization is minimal compared to nitrogen made available by microorganisms.

Plants use the nitrate and ammonia to make proteins. Another point for Bula, the acid part of the amino acid is called a carboxyl group. It is COOH, which disassociates to form COO (with a negative charge) and H (with a positive charge). H with a positive charge is called a "proton". Acidity is due to the proton concentration. So, amino acids have an amine (NH3) plus an acid (COOH) attached to a carbon atom. Hence the name amino acid.

Bula, there is a saying, "People who live in glass houses ought not throw stones."

Answer 3

nitrogen (N), in protein: -NH3 is the amino function of the amino acids: organic acids in the structure of a protein; Philly Guy is stupid: if the air that he breath contain N (nitrogen) more than 50 % he was already dead...or may be Philly Guy is a alien being form. For Philly Guy: the symbol of nitrogen is N, for oxygen is O, for hydrogen is H....chemistry wasn`t your best!
An other stupid biochemist is Phoolish,: fertilizer is an-organic, and it`s very toxic for human health, or may be Phoolish is an alien too.....
I HATE STUPIDITY!!!!....AND ALIENS TOO......

Answer 4

From nitrogen rich foods.

Answer 5

About half of the nitrogen in our bodies is created artificially in factories... as fertilizer for the foods we eat.

Without such artificial fertilizer the Earth could not support the present population.

Answer 6

The air we breathe contains like 75% nitrogen. I would assume that we get mostly from there

Answer 7

we process these from the food we eat. Proteins from both animal and vegetable sources have nitrogen in them.

Answer 8

We get nitrogen from the plants.

Answer 9

from the food we eat which is processed in our bodies to produce nitrogen and other components needed by our organs.

Answer 10

From food
