Leucine ball and stick model spinning. Leucine (symbol Leu or L) [3] is an essential amino acid that is used in the biosynthesis of proteins.Leucine is an α-amino acid, meaning it contains an α-amino group (which is in the protonated −NH 3 + form under biological conditions), an α-carboxylic acid group (which is in the deprotonated −COO − form under biological conditions), and a side ...
The Food and Nutrition Board (FNB) of the U.S. Institute of Medicine set Recommended Dietary Allowances (RDAs) for essential amino acids in 2002. For leucine, for adults 19 years and older, 42 mg/kg body weight/day; for isoleucine 19 mg/kg body weight/day; for valine 24 mg/kg body weight/day. [6]
Leucine is an essential amino acid, and its degradation is critical for many biological duties. [ 3 ] α-KIC is produced in one of the first steps of the pathway by branched-chain amino acid aminotransferase by transferring the amine on L-leucine onto alpha ketoglutarate , and replacing that amine with a ketone .
The distinction between essential and non-essential amino acids is somewhat unclear, as some amino acids can be produced from others. The sulfur-containing amino acids, methionine and homocysteine, can be converted into each other but neither can be synthesized de novo in humans. Likewise, cysteine can be made from homocysteine but cannot be ...
Vitamin deficiencies may result in disease conditions: goiter, scurvy, osteoporosis, impaired immune system, disorders of cell metabolism, certain forms of cancer, symptoms of premature aging, and poor psychological health (including eating disorders), among many others. [82] Excess levels of some vitamins are also dangerous to health.

Omega-3 and omega-6 fatty acids in fish oil may help prevent several types of cancer, including colon, stomach, and lung cancers, a new study suggests. ... fatty acids play an essential role in a ...
Tissue culture flasks. RPMI 1640, simply known as RPMI medium, is a cell culture medium commonly used to culture mammalian cells. [1] RPMI 1640 was developed by George E. Moore, Robert E. Gerner, and H. Addison Franklin in 1966 at Roswell Park Comprehensive Cancer Center (formerly known as Roswell Park Memorial Institute), from where it derives its name. [2]
