Protein: Four Major Building Materials In The Human Body

One aspect of nutrition that is vital is protein. Protein is one of four major building materials in the human body. Proteins are composed of carbon with Hydrogen, Oxygen, and Nitrogen attached. Some proteins also have Sulfur, Phosphorus, and Iron. Proteins are made up of sub-units called amino acids, of which there are twenty. These are just the basics of what proteins are composed of. Amino acids, which are the sub-units of Proteins, can be divided into two groups. Eleven of the twenty amino acids can be made in the body, while the other nine have to be acquired through the diet. Amino acids themselves can be divided into two main parts. The first is the amino group (-NH2). The amino group is the chemical portion of an amino acid and contains Nitrogen. The second part of an amino acid is the acid group (-COOH). Amino acids are vital to the construction of all proteins. Consequently, the overall worth of a protein food is determined by its amino acid composition. The recommended daily allowance (RDA) is a term that is used to speak about how much of a certain food you should consume on a daily basis. The recommended daily allowance for protein is eight tenths of a gram of protein per two and two tenths of a pound. What this means is that for every two and two tenths of a pound that you weigh,
For example, foods as healthy as whole grain bread and as unhealthy as candy are made of the same base macromolecule of carbohydrates. This is because there are different types of carbohydrates called monomers. There many more monosaccharides that could be talked about, but the main three are glucose, fructose, and galactose. Glucose is the essential sugar unit that is made by plants during photosynthesis. Fructose is the type of sugar that is found in fruits like apples or peaches. Galactose is the type of sugar that is found in substances such as milk and is normally paired with other simple
