Description
Hydroxythreonine, also known as 4-Hydroxy-L-threonine, is a hydroxy-amino acid derived from L-threonine, an essential amino acid for human development. It is the last of the common amino acids to be discovered and has been identified in oat protein. Hydroxythreonine consists of L-threonine with a hydroxy substituent at the 4-position, playing a significant role in various biological processes.
Uses
Used in Pharmaceutical Applications:
Hydroxythreonine is used as a pharmaceutical agent for its potential role in human development and health. As a metabolite of L-threonine, it contributes to the overall amino acid pool in the body, which is essential for protein synthesis and various metabolic functions.
Used in Nutritional Supplements:
Hydroxythreonine is used as a nutritional supplement to support the body's amino acid requirements. It can be particularly beneficial for individuals with specific dietary needs or those looking to enhance their protein intake for muscle growth and repair.
Used in Research and Development:
Hydroxythreonine is used as a research compound in the field of biochemistry and molecular biology. Its unique structure and properties make it an interesting subject for studying the functions and interactions of amino acids in biological systems.
Used in Food Industry:
Hydroxythreonine can be used in the food industry as a natural additive or enhancer, potentially improving the nutritional value of certain products. Its presence in oat protein also makes it a valuable component in the development of health-focused food products.
Check Digit Verification of cas no
The CAS Registry Mumber 21768-45-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,7,6 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 21768-45:
(7*2)+(6*1)+(5*7)+(4*6)+(3*8)+(2*4)+(1*5)=116
116 % 10 = 6
So 21768-45-6 is a valid CAS Registry Number.
