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.

has two main functions: an exocrine function that helps in digestion and an endocrine function that regulates blood sugar.

Molecular biology deal with the biological functioning of macromolecules, e.g. how proteins function, how DNA is transcribed, etc, whereas biochemistry deals with the chemical reactions of biological systems, e.g. the kinetics of enzymes, how chemicals are broken down in reactions and the repsonsible enzymes.

Proteins fold up into specific shapes according to the sequence of amino acids in the polymer, and the protein function is directly related to the resulting 3D structure. Proteins may also interact with each other or other macromolecules in the body to create complex assemblies.

Primary structure. The simplest level of protein structure, primary structure, is simply the sequence of amino acids in a polypeptide chain. For example, the hormone insulin has two polypeptide chains, A and B, shown in diagram below.

The major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code. To read the genetic code, cells make a copy of a stretch of DNA in the nucleic acid RNA.

The main function of nucleic acids is to store and transmit genetic information and use that information to direct the synthesis of new protein.

The Role of Proteins in Foods: Cooking and Denaturation. In addition to having many vital functions within the body, proteins perform different roles in our foods by adding certain functional qualities to them. Protein provides food with structure and texture and enables water retention.

Cellular functions include such basic life processes as protein and lipid (fat) synthesis, cell division and replication, respiration, metabolism, and ion transport as well as providing structural support for tissues, protecting the body against disease or injury, and serving as selective barriers to the passage of ...

There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids); each is an important cell component and performs a wide array of functions. Combined, these molecules make up the majority of a cell's dry mass (recall that water makes up the majority of its complete mass).

Your body uses protein to build and repair tissues. You also use protein to make enzymes, hormones, and other body chemicals. Protein is an important building block of bones, muscles, cartilage, skin, and blood.

Membrane carbohydrates perform two main functions: participate in cell recognition and adhesion, either cell-cell signaling or cell-pathogen interactions, and they have a structural role as a physical barrier.

The primary function of mRNA is to act as an intermediary between the genetic information in DNA and the amino acid sequence of proteins. mRNA contains codons that are complementary to the sequence of nucleotides on the template DNA and direct the formation of amino acids through the action of ribosomes and tRNA.

Proteins are important structural and functional biomolecules that are a major part of every cell in your body. There are 2 nucleic acids -- DNA and RNA. Your cells make proteins by following the instructions encoded in your DNA, which is genetic material and a type of nucleic acid.
