Answer 1

Amino acids.

Answer 2

Amino acids (apex)

Answer 3

Amino acids are the building blocks of proteins.

Proteins are of primary importance to the continuing functioning of life on Earth. Proteins catalyze the vast majority of chemical reactions that occur in the cell. They provide many of the structural elements of a cell, and they help to bind cells together into tissues. Some proteins act as contractile elements to make movement possible. Others are responsible for the transport of vital materials from the outside of the cell ("extracellular") to its inside ("intracellular"). Proteins, in the form of antibodies, protect animals from disease and, in the form ofinterferon, mount an intracellular attack against viruses that have eluded destruction by the antibodies and other immune system defenses. Many hormones are proteins. Last but certainly not least, proteins control the activity of genes ("gene expression").

This plethora of vital tasks is reflected in the incredible spectrum of known proteins that vary markedly in their overall size, shape, and charge. By the end of the 19th century, scientists appreciated that, although there exist many different kinds of proteins in nature, all proteins upon their hydrolysis yield a class of simpler compounds, the building blocks of proteins, called amino acids. The simplest amino acid is called glycine, and it was one of the first amino acids to be identified, having been isolated from the protein Gelatin in 1820. In the mid-1950s scientists involved in elucidating the relationship between proteins and genes agreed that 20 amino acids (called standard or common amino acids) were to be considered the essential building blocks of all proteins. The last of these to be discovered, threonine, had been identified in 1935.

Answer 4

Amino acids are the basic building blocks of protein. There are two categories of amino acids which are essential and nonessential. These include substances like glycine and alanine and will produce polypeptides. There are around 500 amino acids, and they are composed of carbon, hydrogen, oxygen, and nitrogen.

Protein molecules are built up from peptide molecules, which are themselves built up from amino acid molecules joined together by peptide bonds.
Amino-acids are the building blocks of protein. There are 20 types of amino-acids and they are split into two different groups: essential and non-essential.
Proteins are made up of amino acids. Twenty such amino acids are naturally occurring in polypeptides, nine of which are regarded as 'essential' for survival.

Answer 5

The building blocks of proteins are amino acids, which are small organic molecules that consist of an alpha (central) carbon atom linked to an amino group, a carboxyl group, a hydrogen atom, and a variable component called a side chain.

Answer 6

The building blocks of proteins are called amino acids.
The building blocks that make up proteins are amino acids.

Answer 7

Proteins are built from one or more polypeptides, which are themselves built from peptides, which are themselves built from two or more amino acids.

Answer 8

There's not much to say about that except "yes."

Well, some proteins have cofactors, which are not amino acids, but by and large it's correct.

Answer 9

Amino Acids.

Answer 10

amino acids.
