Amino acids
any of a cl-ss of organic compounds that contains at least one amino group, –nh 2 , and one carboxyl group, –cooh: the alpha-amino acids, rch(nh 2)cooh, are the building blocks from which proteins are constructed.
historical examples
a moment ago we saw that in the case of the amino acids the nitrogen is removed before they are ready for use as fuel.

the protein molecule is made up of a number of organic units known as amino acids.

thus the proteins are digested down to the amino acids and these diffuse into the blood as demonstrated by folin and by van slyke.

proteins which contain all the amino acids essential for tissue building are known as complete proteins.

these organic acids all contain nitrogen, which puts them into a cl-ss to which is given the name of amino acids.
physiology ernest g. martin
the different proteins differ in regard to the different types of amino acids which they contain.
the organism as a whole jacques loeb
some of the amino acids that make up a large proportion of animal protein are very scantily represented in plant protein.

these transformed substances are known as amino acids, the production of which is a result of digestion in the digestive tract.

noun
any of a group of organic compounds containing one or more amino groups, -nh2, and one or more carboxyl groups, -cooh. the alpha-amino acids rch(nh2)cooh (where r is either hydrogen or an organic group) are the component molecules of proteins; some can be synthesized in the body (nonessential amino acids) and others cannot and are thus essential components of the diet (essential amino acids)
amino acid n.
abbr. aa
any of various organic acids containing both an amino group and a carboxyl group, especially any of the 20 or more compounds that link together to form proteins.
amino acid
any of a large number of compounds found in living cells that contain carbon, oxygen, hydrogen, and nitrogen, and join together to form proteins. amino acids contain a basic amino group (nh2) and an acidic carboxyl group (cooh), both attached to the same carbon atom. since the carboxyl group has a proton available for binding with the electrons of another atom, and the amino group has electrons available for binding with a proton from another atom, the amino acid behaves as an acid and a base simultaneously. twenty of the naturally occurring amino acids are the building blocks of proteins, which they form by being connected to each other in chains. eight of those twenty, called essential amino acids, cannot be synthesized in the cells of humans and must be consumed as part of the diet. the remaining twelve are nonessential amino acids.
amino acids [(uh-mee-noh)]
basic organic molecules that combine to form proteins. amino acids are made up of hydrogen, carbon, oxygen, and nitrogen. some examples of amino acids are lysine, phenylalanine, and tryptophan.
note: amino acids are the basic molecular building blocks of proteins.
