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 class to which is given the name of amino acids.
The different proteins differ in regard to the different types of amino acids which they contain.
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.
amino acid n.
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.
