amino acid.

Definition of amino acid. in English English dictionary: AA; Any of the twenty naturally occurring α-amino acids (having the amino, and carboxylic acid groups on the same carbon atom), and a variety of side chains, that combine, via peptide bonds, to form proteins; Any organic compound containing both an amino and a carboxylic acid functional group; phenylalanine; organic compounds containing an amino group and a carboxylic acid group; "proteins are composed of various proportions of about 20 common amino acids"; A molecule of the general formula NH2-CHR-COOH, where "R" is one of a number of different side chains Amino acids are the building blocks of proteins The sixty-four codons of the genetic code allow the use of twenty different amino acids (the primary amino acids) in the synthesis of proteins Other nonprimary amino acids occur in proteins by enzymatic modification of amino acids in mature proteins, and as metabolic intermediates See the Figure at NHGRI For Figures showing the structure of each of the twenty primary amino acids, see Figure 1 and Figure 2 from "Molecular Biology of the Cell" by Alberts et al; An organic compound which contains one or more amino groups As a rule, the term refers to the 20 alpha amino acids, which are the building blocks of all proteins Proteins are the basis of almost all active life processes in animals and plants Phenylalanine is an amino acid; Amino acids are the building blocks of protein Amino acids join together and form short chains (peptides) or much longer chains (polypeptides) Over 80 amino acids are known to occur naturally,with 20 found commonly in protein polypeptides; The building block of proteins The quality of a specific protein source is down to it's make up of different amino acids; Building blocks of proteins; Amino acids are substances containing nitrogen and hydrogen and which are found in proteins. Amino acids occur naturally in the body. An organic compound containing an amino group (NHCHRCOOH, and that link together by peptide bonds to form proteins or that function as chemical messengers and as intermediates in metabolism. one of the substances that combine to form proteins (amine type of chemical compound (19-21 centuries), from ammonia). Any of a class of organic compounds in which a carbon atom has bonds to an amino group (NH2), a carboxyl group (COOH), a hydrogen atom (H), and an organic side group (called R). They are therefore both carboxylic acids and amines. The physical and chemical properties unique to each result from the properties of the R group, particularly its tendency to interact with water and its charge (if any). Amino acids joined linearly by peptide bonds (see covalent bond) in a particular order make up peptides and proteins. Of over 100 natural amino acids, each with a different R group, only 20 make up the proteins of all living organisms. Humans can synthesize 10 of them (by interconversions) from each other or from other molecules of intermediary metabolism, but the other 10 (essential amino acids: arginine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine) must be consumed in the diet; n (a-MEE-no) Organic acid containing one or more amino groups, especially any of a group that make up proteins and are important to living cells Some can be synthesized by the body (nonessential amino acids) and others must be obtained through the diet (essential amino acids); The molecular building blocks for proteins; amino acids are the building blocks of proteins; only about 20 amino acids are used to build the thousands of kinds of proteins needed by living cells; One of the building blocks of proteins in the body; The fundamental building blocks of a protein molecule A protein is composed of a chain of hundreds or thousands of amino acids Our bodies can synthesize most of the amino acids However, eight amino acids (called "essential amino acids") must be obtained from food; organic compounds containing an amino group and a carboxylic acid group; "proteins are composed of various proportions of about 20 common amino acids; The basic building block of protein All amino acids contain an amino (NH2) end, a carboxyl end (COOH) and a side group (R) In proteins, amino acids are joined together when the NH2 group of one forms a bond with the COOH group of the adjacent amino acid The side group is what distinguishes each of the amino acids from the others; The molecule which is the building block of proteins The 20 different amino acids which make up proteins all have a similar structure, with an amino group, a carboxyl group and one of 20 different chemical side chains, all attached to a central carbon atom; Any of the 20 subunits that are the basic building blocks of proteins The sequence of amino acids in a protein and, hence, the function of a protein are determined by the genetic code; The basic building blocks for proteins in the body Amino acids can be made by the body from other substances and are also ingested from eating foods with protein; One of the essential building blocks from which proteins are made Amino acids have the generic formula H3N+CHRCO2-; organic compound from which proteins are made; One of the 20 building blocks of protein; Any of a class of 20 molecules that are combined to form proteins in living things The sequence of amino acids in a protein and hence protein function are determined by the genetic code; - Any of 20 different molecules that can be chemically strung together to form proteins The shape and function of a protein is determined by which amino acids are used and in which sequence; The fundamental building block of proteins There are 20 naturally occurring amino acids in animals and around 100 more found only in plants; any of the 26 chemical building blocks of proteins; The basic unit of proteins The human body makes some amino acids, while others, called essential amino acids, are obtained only from foods containing protein; Large organic molecule: building block of protein; The building blocks of protein There are 20 common amino acid molecules that can be combined to form proteins in living things The genetic code determines the sequence of amino acids in a protein, which governs the protein's function Enzymes are proteins; an organic compound that is a basic structural unit of peptides and proteins; {i} cysteine; {i} alanine
