are residuals the same as amino acids?

The parts of an amino acid are an amine group, a carboxylic acid group, and the residue. The amine and carboxylic acid groups give the name 'amino acid,' and these two parts are identical to those of other amino acids. The residue is the part that is unique among each of the 20 amino acids.

Proteins are built from a set of only twenty amino acids, each of which has a unique side chain. The side chains of amino acids have different chemistries.

Nine amino acids—histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine—are not synthesized by mammals and are therefore dietarily essential or indispensable nutrients. These are commonly called the essential amino acids.

Amino acid chart. There are 20 amino acids that make up proteins and all have the same basic structure, differing only in the R-group or side chain they have. ... They can be subdivided according to their properties, dictated by the functional groups they possess.
296088
All amino acids have the alpha carbon bonded to a hydrogen atom, carboxyl group, and amino group. The "R" group varies among amino acids and determines the differences between these protein monomers. The amino acid sequence of a protein is determined by the information found in the cellular genetic code.
1369544
All amino acids have a carboxyl group and an amino group bonded to the same carbon atom (the α carbon). ... Some 300 additional amino acids have been found in cells but they are not constituents of proteins. These amino acids are commonly known as uncommon amino acids.

BCAA's (Branched Chain Amino Acids) and any other Amino Acids are perfectly legal, and like you said are the fundamental components of standard protein sources in your diet. These are ENTIRELY different than PEPTIDE HORMONES which are specifically banned.

ABSTRACT. Methionine, cysteine, homocysteine, and taurine are the 4 common sulfur-containing amino acids, but only the first 2 are incorporated into proteins. Sulfur belongs to the same group in the periodic table as oxygen but is much less electronegative.

Every amino acid also has another atom or group of atoms bonded to the central atom known as the R group (Figure 1). The name “amino acid” is derived from the fact that they contain both amino group and carboxyl-acid-group in their basic structure. As mentioned, there are 20 amino acids present in proteins.

There are three amino acids that have basic side chains at neutral pH. These are arginine (Arg), lysine (Lys), and histidine (His). Their side chains contain nitrogen and resemble ammonia, which is a base.
659701
Lysine and arginine are basic amino acids because their side chain group contains a full positive charge at the physiological pH. Histidine is also considered basic but it can have a positive or a neutral charge on its side chain group at the physiological pH.

Despite such variety, proteins also share several specific structural characteristics in their monomers, the amino acids. Structural similarities among amino acids make protein synthesis a uniform and regulated process; however, each amino acid contains a unique structural component as well.

Charge of the amino acid side chains At pH=7, two are negative charged: aspartic acid (Asp, D) and glutamic acid (Glu, E) (acidic side chains), and three are positive charged: lysine (Lys, K), arginine (Arg, R) and histidine (His, H) (basic side chains).

The main differences between the amino acid profiles of whey and collagen are that whey contains all 9 essential amino acids, while collagen only has 8. ... Collagen supplements may easily be made into a complete protein by simply adding the missing essential amino acid, which is what we do with our Frog Fuel products.

CHEBI:33708 - amino-acid residue When two or more amino acids combine to form a peptide, the elements of water are removed, and what remains of each amino acid is called an amino-acid residue.

Pyrrolysine (considered the 22nd amino acid) is not used by humans; thus, it is non‑essential. The limiting amino acid is the essential amino acid found in the smallest quantity in the foodstuff.

Amino acids are organic compounds composed of nitrogen, carbon, hydrogen and oxygen, along with a variable side chain group. Your body needs 20 different amino acids to grow and function properly. Though all 20 of these are important for your health, only nine amino acids are classified as essential ( 1 ).
