Proteins

Proteins what elements are they composed of?

Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON). Nucleic acids such as DNA and RNA contain carbon, hydrogen, oxygen, nitrogen, and phosphorus (CHON P). The body also needs trace amounts of other elements such as calcium, potassium, and sulfur for proper functioning of muscles, nerves, etc.

What elements are they composed of proteins Brainly?

Answer: Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON).18 oct. 2020

What is the scientific name of protein?

A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called peptides, or sometimes oligopeptides.

What is the chemical name for protein?

Although amino acids may have other formulas, those in protein invariably have the general formula RCH(NH2)COOH, where C is carbon, H is hydrogen, N is nitrogen, O is oxygen, and R is a group, varying in composition and structure, called a side chain.

What are proteins functions?

Protein has many roles in your body. It helps repair and build your body’s tissues, allows metabolic reactions to take place and coordinates bodily functions. In addition to providing your body with a structural framework, proteins also maintain proper pH and fluid balance.20 jui. 2018

What elements are they composed of carbohydrates?

Carbohydrates are composed of carbon, hydrogen, and oxygen and have a general formula that approximates CH2O. They are polyhydroxy aldehydes or ketones or form polyhydroxy aldehydes or ketones when hydrolyzed. Carbohydrates occur as monosaccharides, disaccharides, oligosaccharides, and polysaccharides.

What are proteins examples?

Complete proteins include meat and dairy products, quinoa, hemp seeds, chia seeds and soy. Many plant-based proteins are not complete proteins. These include beans, grains and legumes as well as vegetables, which contain small amounts of protein.9 déc. 2015

Where are proteins found?

Protein is found throughout the body—in muscle, bone, skin, hair, and virtually every other body part or tissue. It makes up the enzymes that power many chemical reactions and the hemoglobin that carries oxygen in your blood. At least 10,000 different proteins make you what you are and keep you that way.

Which is protein in nature?

A protein is a naturally occurring, extremely complex substance that consists of amino acid residues joined by peptide bonds. Proteins are present in all living organisms and include many essential biological compounds such as enzymes, hormones, and antibodies.

Are proteins acidic or basic?

Proteins usually are almost neutral molecules; that is, they have neither acidic nor basic properties. This means that the acidic carboxyl ( ―COO−) groups of aspartic and glutamic acid are about equal in number to the amino acids with basic side chains.
