Protein is recognized as more than a very complex, high-molecular-weight substance with certain biological value. It is designated by its profile of available amino acids, the units needed to produce enzymes and protoplasm. Proteins cannot be classified simply on the basis of their chemical make...
All these 'essential' amino-acids are not present in every protein. With a knowledge of the amino-acid composition of the various animal and vegetable proteins, it is possible to choose proteins so that they become mutually supplementary, and thus to ensure a diet that contains the qualitative...

Cosmetics:D-amino acids could improve skin quality. D-Asp has both an antioxidant and collagen production-promoting effect. D-Glu can recover barriers and reduce wrinkle formation and skin roughness. D-Ser can reduce ultraviolet damage. Due to these effects on skin quality, D-amino acids of an...
also known as the C or carboxyl terminal. While the terms polypeptide and protein are sometimes used interchangeably, a polypeptide is technically a polymer of amino acids, whereas the term protein is used for a polypeptide or polypeptides that have combined together, often have bound non-peptide...

Find out whether amino acid supplements offer more benefits or risks to your health. Amino acids are the building blocks of protein, essential for forming proteins in the body.
It is possible that some of these nonprotein amino acids may serve as insecticidal or fungicidal agents. Humans and monogastric animals are not able to synthesize the following nine amino acids: lysine, threonine, methionine, phenylalanine, tryptophan, isoleucine, leucine, valine, and histidine. ...
Proteinogenic amino acids are a group of amino acids that are naturally incorporated into proteins. They can be either sweet or intensely sweet, with some being 35 times sweeter than sucrose. AI generated definition based on: Comprehensive Natural Products II, 2010 ...
